THE WATERPROOF/BREATHABLE DRYSUIT SHELL
USE AND CARE MANUAL
A) SROB SPECIFICATIONS O.S Systems, Inc. (OS SYSTEMS) makes two models of its SARR
Surface Water Rescue Drysuits that are waterproof and breathable,
the Splash-B-SROB (SPLB-SROB) and the Splash-B-SRBEC (SPLB-SRBEC).
The SROB is a full featured drysuit having all of the features
described below. The SRBEC is the economy version of the same
drysuit. Both drysuits are made with the same fabrics, zippers,
seals, glue, tape, quality, etc. Only the extra features
differentiate the two models. This Manual applies to both.
The SROB Drysuit Shell is a full body garment designed to prevent
the intrusion of water into the shell when the wearer is immersed
in water. The SROB is a fabric drysuit and does not provide any
significant thermal protection by itself. Each user must wear the
appropriate undergarments for thermal protection
The main body of the SROB shell is made from the MICRO
waterproof/breathable fabric. The MICRO fabric is a three layer
laminate having an exterior base/face fabric, a waterproof &
breathable barrier membrane, and a protective tricot fabric inside
layer. The face fabric is treated with a DWR (Durable Water
Repellent) solution treatment to aid in evaporation of water
vapor.
The SROB Drysuit Shell is equipped with a front diagonal entry, a
#8 diving quality, brass tooth zipper, and a Cordura® fabric
Zipper Cover. This allows easy and fast donning and doffing, and
guaranteed water tightness.
Knee, Butt, and Elbow/Forearm pads are Cordura® for protection and
increased traction. Neoprene Shin Guards are installed inside the
Knee Pads to protect the knees and shins.
The waist of each SROB Drysuit is secured by an adjustable cord
waist inside the SROB so that nothing is external, exposed and
vulnerable to being snagged.
External Bellows Pockets (S, M, or L) can be installed. These
pockets are secured with sandwich style Velcro flap/closures.
Quick drain mesh is installed on each pocket.
Each SROB Drysuit is equipped with Longlife Latex rubber neck and
wrist seals, and MICRO fabric socks, to prevent water intrusion.
Please specify foot size.

LongLife seals are thicker (minimum thickness specification is
.026"), more durable than standard recreational seals, and are
easily replaced. The instructions for seal replacement are in the
Repair Center section below. Additional instructions and helpful
hints are available at "www.ossystems.com/repair/repr.htm', and at
"www.ossystems.com/repair/seals.html".
Cordura/neoprene Wrist Wraps, Ankle Wraps, and a Neck Wrap
cover and protect the neck seal, the wrist seals, and the fabric
socks.
Seams are double stitched for strength, and fusion sealed on the
inside for water tightness.
The SROB Drysuit Shell is designed with Freedom Cut features to
maximize user mobility. Sidearm Panel Gussets extend from the
elbows all the way down the arm and past the waist. The Crotch
gusset extends from one ankle through the crotch and all the way
down to the opposite ankle for unparalleled fit, function and
freedom of movement. The SROB Drysuit will not restrict the
user’s physical mobility.
Each SROB Drysuit Shell is individually tested under pressure and
under water to guaranty water tightness.
Each SROB Drysuit Shell carries a two year limited warranty.

Page 3 of 19
1. Sizing The first step in wearing SROB is to make sure that your SROB is
the correct size drysuit for you.
Height is the most important measurement to consider. The MICRO
fabric does not stretch. The SROB Drysuit Shell that you select
must have adequate room in the ease of the pattern to allow you to
reach, bend over, squat, and move around, without feeling any
restrictions from the SROB. Do not select a SROB size that is
designed for a person who is shorter than you. See the Drysuit
Sizing Page at the end of this Manual.
2. Donning Dress in the combination of undergarments that you anticipate
needing for your metabolic and activity level in, and length of
exposure to, the environment you anticipate encountering.
Make sure that you have applied UV TECH to the inside and outside
of your neck and wrist seals. Make sure you have Zipease recently
applied to the teeth of the zipper so that the zipper slider will
open and close easily. Check to make sure there is no sand or
other material caught in the Zipease that might obstruct the
zipper teeth when closing. Remove any watches, rings, earrings,
or any item that might catch and tear the seals, and trim any long
or jagged fingernails.
Open the Zipper cover and fold it back so that the Velcro on the
cover will not catch on anything. Open the zipper to its maximum
opening. Unzip the Neck Wrap, and open the Wrist and Ankle Wraps
fully to allow for the easiest entry.
Begin donning by sitting on a chair and inserting one leg into
that leg of the SROB, like you step into your trousers, with the
zipper in front. Extend your leg and foot down into the shell and
into the fabric sock, pushing your toe all the way into the end of
the sock. If there is any extra room in the sock, fold the extra
fabric over at the back of the sock. Put your shoe or boot on now
and lace it up.
Repeat this process for your other leg.
Grab the waist of your SROB and Pull the waist band of the SROB up
and set it into position so that the crotch area is snug yet
comfortable (setting the crotch).
Put on and adjust the suspenders.
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 4 of 19
Insert your left hand and arm into the left arm of your SROB.
Pull the left shoulder of your SROB fully over your left shoulder,
extending your left arm down into the sleeve and to the wrist
seal. Hold your straightened fingers together so that they form
one single unit pushing through the wrist seal. As your fingers
emerge through the wrist seal, open your fingers and continue
pushing and working your fingers, then your hand, and finally your
wrist through the wrist seal opening and into the proper position.
The sealing area of the wrists seal should be at or just above
your wrist bone. Make sure the wrist seal lays flat on your
wrist.
Raise both arms high above your head pulling the SROB up again to
reset the crotch.
Repeat the sleeve entry process for the right sleeve.
Your SROB up and reset the crotch.
Again, pull
Insert four fingers from each of your hands, spread widely apart,
into the top of the circular opening of the neck seal. Stretch
the neck seal carefully open and down over your head and onto your
neck. The neck seal lays flat on the neck with its upper edge
slightly below your chin level. Adjust the neck seal up or down
for comfort and improved sealing. Work out any wrinkles or folds
in the neck seal. Zip the Neck Wrap closed.
Neck seal adjustment is discussed in the Maintenance Section of
this SROB Manual.
Use your left hand to hold the SROB fabric and entry zipper of the
SROB above your left shoulder. Slowly pull the zipper slider,
with your right hand, along the line of the zipper, as parallel to
the teeth as practical. After your zipper is closed, give the
slider one final pull to make sure it is fully closed. Fold the
zipper cover down over the zipper and attach the Velcro to Velcro
to secure it.
You now are watertight, but your SROB is probably full of air.
You need to burp your SROB. Stand straight up with one finger
from each hand in the opening of the neck seal, pulling it
slightly off of the neck. Squat slowly, with your elbows pressing
tightly against your sides. You will feel and hear the extra air
rushing out through the neck seal opening.
When the air has stopped flowing out, remove your fingers from the
neck seal, allowing the seal to return to its sealed position
against your neck. Stand up. You are now burped and vacuum
packed. You may remove additional air by repeating this burping
process. If you feel a little too squeezed, you may add a little
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 5 of 19
air back into your SROB by slightly opening the neck seal.
your own comfort level.
Find
Determine your final comfort level, and once again, set the
crotch!!
Additional burping may be done when you enter the water. Submerse
yourself up to the level of your arm pits. Bring your arms in
close against your body. With one hand, reach up and vent your
neck seal until sufficient air has escaped. Do not lower the neck
seal into the water or water will flood into your SROB!
Your SROB is equipped with suspenders so the crotch will remain
properly positioned and set.
3. Wearing Once you have donned your SROB, double check the size. Make sure
that your crotch remains set. If the crotch of your SROB rides up
too tightly, you will feel obvious pain. If it rides down too
far, you will feel restrictions in moving your legs.
Stand up straight and reach high over your head. Reach down and
touch your toes, Reach from side to side. Pick one foot up and
step over some obstruction. Duplicate any motions you anticipate
needing to be able to do in the SROB.
Refer to the Maintenance Section of this Manual for techniques to
fit neck and wrist seals to make them more comfortable.
Your SROB Drysuit Shell can be worn continuously, as an outside
garment, or inside, under additional clothing. The MICRO fabric
is waterproof and highly breathable (Water Vapor Transmissible).
Water stays out, but your sweat will be transmitted through the
waterproof/breathable membrane and will evaporate from the
outside, base fabric. Wearing your SROB Drysuit under additional
clothing will reduce breathability.
The engine that drives the process of breathability in the SROB
drysuit shell is the heat your body generates from activity.
Be sure to wear undergarments that are compatible, and will
transmit water vapor (wick sweat) away from your skin and out to
the shell. The membrane of the shell will transmit the water
vapor to the outside face fabric where it will evaporate. DO NOT
WEAR COTTON OR WOOL OR ANY OTHER FABRIC THAT HOLDS MOISTURE OR
INTERFERES WITH THIS MOISTURE VAPOR TRANSMISSION
Within reason, you will stay comfortable in warmer and colder
climates, dry or wet. For extreme activity conditions, no drysuit
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 6 of 19
fabric can immediately transmit the heat you generate, but the
SROB will rapidly catch up once your activity level slows down.
Remember that the rubber neck and wrist seals are not breathable.
Sweat will build up under those seals.
Rubber seals are very susceptible to punctures and tears. All
drysuit fabrics must be kept unpunctured to be dry. The SROB has
reinforcing pads, Wraps, and covers in critical areas to protect
the SROB fabric. See the Repair Section of this Manual for repair
procedures.
4. Doffing Remove your SROB Drysuit by reversing the Donning procedures.
Protect the rubber seals by removing any watches, etc. that might
cut or tear the rubber. When grabbing, stretching or pulling
seals, you should use several fingers to spread out the stress.
5. Storing Clean the rubber seals, zippers, and MICRO fabric of your SROB
Drysuit as described in the Maintenance Section of this Manual.
Apply UV TECH, Zipease, and DWR treatments as indicated.
Make sure the front entry and relief zippers are left in the fully
open position. DO NOT CLOSE ANY BRASS TOOTH ZIPPER WHEN STORING.
Make sure your SROB is dry before closing any pockets or rolling
or folding your SROB. The best way to dry your SROB is to hang it
in a shaded area where there is a breeze, out of the sun and away
from the heat.
Reattach all Velcro Zipper Covers and pocket flaps.
Lay your SROB Drysuit flat, zippers facing down, and, beginning
with the toes of the fabric socks, roll the SROB up all the way to
the neck seal. Fold the arms of the SROB over the rolled up SROB
and lightly secure the bundle with a strap or rubber band. Place
your SROB in a storage bag.
Store your SROB protected from exposure to heat, UV radiation, and
ozone, as much as possible.
C) SROB INSPECTION CHECKLIST -
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 7 of 19
1. Inspect your SROB (before & after) Each Use (a) Neck & Wrist Seals Look at the outer edge of all latex seals. Look for a V notch
starting that can lead to seal splitting. Look for cracking or
checking in the latex material. Look for a soft/gummy feeling to
the latex.
If you find ANY of these problems do not use the suit.
the seal.
Replace
If there are any areas where the latex is lifting slightly from
the SROB, apply a small touch of PB-300 to the area and press the
seal back down to the fabric.
(b) Entry and Relief Zippers With the zippers FULLY in the open position, inspect the brass
rivets that line each side of the zipper opening. Drape each side
of the zipper over your non-dominant hand (the edge of the zipper
will form a U shape) pass all of the brass rivets over the top of
your hand while you look for any that are broken or misaligned.
Look for excessive wax buildup and dirt in between the rivets.
Clean with a toothbrush and mild soap if you find either. Reapply
Zipease to the teeth of the zipper.
Inspect the small teeth on the inside edge of the zipper. These
teeth interlock to hold the sealing area of the zipper together.
Look for any missing or misaligned teeth.
Look for wax or dirt
(there should be none). Clean with a toothbrush and mild soap if
you find wax or dirt.
Apply Zipease to the outer rivets ONLY. Open and close the zippers
once before donning the suit.
(c) Shell Fabric (MICRO)Turn the suit inside out and look for holes, punctures and tears
paying special attention to the bottom of the attached socks.
Patch as needed.
Look at the seams and the taping. If any is lifting, apply a
touch of PB-300 and press the seam down.
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 8 of 19
Now turn the suit right side out and inspect for holes, punctures
and tears paying special attention to the bottom of the attached
socks, and patch as needed.
Inspect the pockets, zipper covers, Neck, Wrist and Ankle Wraps
for signs of wear or separation from the body of the suit.
If you find any of these problems do not use the suit until it is
repaired.
2. Inspect your SROB every 30 days Conduct the same inspection of your SROB every 30 days, even if
you have not used it. Exposure to heat and the elements can cause
deterioration that might require some repair.
D) MAINTENANCE 1. Shell Fabric (MICRO)After each use, gently wash the inside of the MICRO fabric with a
mild solution of hand washing or dishwashing soap. Then spray or
rinse the inside and outside of the fabric with clean water. Hang
dry the inside and outside of your SROB, out of the sun and away
from heat.
Wash the outside of the MICRO fabric with soap only when it cannot
be cleaned with just water. The DWR treatment can be removed
prematurely by excessive washing, usually requiring more than 50
washings.
Test the DWR by dripping water on the outside face fabric. If the
water beads up and is not soaked into the fabric, the DWR is
functioning properly. If the water soaks into the fabric, clean
the face fabric, dry your SROB, and then apply any one of the
readily available commercial DWR treatments to reactivate the
water repellency. Some examples of DWR treatment products are
Scotchguard, Revivex, Nikwax, etc,
Do not apply the DWR treatment to the inside of the MICRO fabric.
DO NOT WASH YOUR DRYSUIT IN ANY WASHING MACHINE! Doing so can
damage the zipper and can cause the seam sealing tape to lift.
2. Seals OS Systems recommends and uses bottle style wrist seals, with
uniquely designed sealing rings. They are more comfortable and
provide the best watertight seal. The sealing area around the
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 9 of 19
wrist is a full 1" tube (more sealing area = more watertight).
This larger sealing area spreads out the squeeze pressure that
makes the watertight seal, eliminating any single point contact
and enhancing user comfort.
OS Systems recommends and uses bell style neck seals. The bell
style neck seal comes with sizing rings on the upper cone portion
of the neck seal. These rings can be trimmed to accommodate
different sized necks, within limits. OS Systems offers four
sizes of adult neck seals, each with conical sizing rings which
can be trimmed to achieve precise individual fit.
(a) The Composition of LongLife Latex Seals OS SYSTEMS designs and owns all of the molds used to dip its
LongLife Latex Seals. LongLife Latex Seals are dipped from only
the best high modulus natural gum latex rubber to maximize memory
and longevity. The latex rubber is surgical grade, with the
addition only of black dye, a minimum amount of ozone inhibitor
and a long life sealant.
LongLife Latex Seals are not hypoallergenic; however, each does
undergo a triple leeching process to minimize the protein content.
Protein content is thought to be a contributing factor in some
allergic reactions to rubber.
(b) Why does rubber degrade?
All rubber, as well as all synthetics, degrades over time. All of
these materials, including natural gum rubber, contain special
oils that are essential structural components called plasticizers.
Over time these plasticizers migrate to the surface of the
material and evaporate. This is called "outgassing". As these
plasticizers are lost, the rubber degrades and becomes brittle,
developing cracks and losing elasticity.
These are signs that
the useable life of the product is being shortened.
The degradation of rubber is accelerated by increased exposure to
UV light from the sun, to ozone, to heat and to petrochemicals,
but this degradation can be dramatically slowed. Examples of
petrochemicals include gasoline, sun tan lotion, scented talcum
powder, and the propellants in some spray cans.
(c) The Care and Maintenance of LongLife Latex Seals -
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 10 of 19
1. After every usage, wash the latex seal inside and outside with
a mild soap and warm water solution (if available) to remove all
contamination that comes from body oils, pollution, lotions, etc.
2. Apply UV Tech to the cleaned latex both on the inside and on
the outside of the seal.
3. Store the suit rolled up in its bag to minimize the airflow
around the seals. This allows the UV Tech to better protect the
latex.
4.
Apply UV Tech to all seals again prior to using the suit.
NOTE: Applying UV Tech to a contaminated seal will only trap
contaminates and accelerate the deterioration.
(d) UV Tech UV Tech is environmentally friendly, water based, industrial
quality protectant and replasticizer that helps preserve natural
gum rubber. UV Tech actually replaces lost plasticizers and helps
seal in existing plasticizers, maintaining the integrity,
suppleness and elasticity of rubber. UV Tech penetrates rapidly,
delivering rejuvenating plasticizers deep into the material and
protecting existing plasticizers. UV TECH does not just remain on
the surface after application, simply making it shiny and greasy.
UV Tech leaves surfaces dry and non-glossy, and will not attract
dirt.
UV Tech contains UV blocking sunscreen that bonds to surfaces,
providing durable protection from UV, ozone, rain-borne soils and
contaminants. A single coat of UV Tech will help considerably,
but for best results use UV Tech once before every usage, and
before each storage. Spray UV Tech liberally over the inside and
outside surfaces of the rubber, or spray on a rag and apply with a
wiping motion. When stored away from sunlight, your seals will
not need to be treated as often. The protection provided by UV
Tech will generally survive several washings and/or usages.
(e) Fitting New Seals New neck, wrist or ankle seals may feel tight or restrictive at
first but will relax a little with use. Seals will feel tighter
in a warm indoors area than they will feel in the cold water
environment.
You can pre-stretch your seals. Pull the wrist seals over a small
bottle. Pull the neck seal over a larger bottle, approximately
23" in circumference. Leave the seals in a stretched position for
O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 11 of 19
only 6 hours at a time. Test fit the seals after the first 6
hours. Repeat the 6-hour sessions as needed until the seals are
comfortable. Make sure that you have applied UV Tech to the latex
prior to stretching.
OS SYSTEMS manufactures 4 sizes of neck seals and 3 sizes of wrist
seals. Make sure that you have the correct size seal installed on
your drysuit BEFORE you start any stretching of the seals.
WARNING!! Never use a seal that is so tight that blood flow is
restricted to the head or hands. Too tight of a neck seal can
lead to a life-threatening situation once in the water.
See the Drysuit Sizing Sheet at the back of this Manual for seal
and sock sizing.
3. Zipper When opening or closing your zipper, pull the zipper head directly
along the line of the zipper, but at a slight angle up from the
fabric of the drysuit. This will keep the zipper head from diving
into the teeth of the zipper.
Store the zipper only in the OPEN POSITION. Close the zipper only
when the drysuit is being used. If you bend the zipper backward or
forward at a sharp angle, especially when the zipper is zipped
closed, you can break the stabilizer cord that holds the teeth in
place. The zipper teeth will then become dislodged and you will
have to replace the zipper, at a great expense to you.
Periodically clean the zipper teeth with a tooth brush and soap
and water. Be sure to remove all sand and any other foreign
particles at every opportunity. After cleaning, lubricate the
zipper teeth with Zipease beeswax lubricant.
NOTICE: This zipper is not warranted by the zipper manufacturer.
Take care of your zipper and it will work well for you for years.

(b) Methyl Ethyl Keytone (MEK)
Methyl Ethyl Keytone (MEK) is an organic solvent. MEK is used in
many plastics, including the polyurethane in the PB-300 adhesive
and the waterproof/breathable membrane in the MICRO fabric. MEK
is the best solvent to clean oils from the areas to be glued, to
clean old PB-300 from the area to be glued, and to thin the PB-300
used to glue seals or MICRO fabric.
NOTE: MEK does dissolve polyurethane. If you use excessive MEK
on the MICRO fabric, you will dissolve the polyurethane and
seriously damage the fabric itself. Use the smallest amount of MEK
possible to accomplish what you need to do!
2. Patching Holes and Punctures in the MICRO Fabric All suit holes and punctures are patched from the inside of the
SROB drysuit. Cut a patch of appropriate size from the SROB
material that is supplied. The patch should be round or oval
shaped, NO CORNERS THAT CAN CATCH AND PULL UP!

is the protective inner lining on the SROB fabric.
The tricot
Clean the area that will be patched with a CLEAN absorbent
material and MEK. Apply 3 coats of PB-300 to the patch and the
area of the suit where that patch will be applied (go ¼ of an inch
beyond the edges of your patch). Allow 3 minutes drying time
between applications of the PB-300 adhesive. After the 3rd
application of the PB-300 adhesive has dried for 2 minutes, and is
still tacky, place the patch over the hole or puncture and apply
firm pressure to affect a good bond between the two pieces. The
suit is ready for use in 30 minutes
For larger punctures and tears, make your patch a sandwich patch,
one on the inside and one on the outside. For the outside patch
glue the tricot of the patch fabric to the face of the drysuit
fabric.
3. Patching holes and punctures in the latex seals The preferred procedure for repairing holes in LongLife Latex
Seals is to replace them. However, if you do want to patch the
hole, an inner tube tire patch kit can be used effectively.
Follow the kit instructions.
Holes in LongLife Latex seals can also be patched using OS SYSTEMS
PB-300 glue.

All seal holes and punctures are patched from the outside of the
seals. Cut a patch of appropriate size from latex rubber material
that is supplied. The patch should be round or oval shaped, NO
CORNERS THAT CAN CATCH AND PULL UP!
Using MEK, clean the area of the rubber seal and the rubber
patching material, where the PB-300 is to be applied. Wipe the
areas dry with a CLEAN absorbent material.
Apply 2 coats of PB-300 to the patch and to the area of the seal
where that patch will be applied (go ¼ of an inch beyond the edges
of your patch). Allow 3 minutes drying time between applications
of the PB-300 adhesive. After the 2nd application of the PB-300
adhesive has dried for 3 minutes and is still tacky, place the
patch over the hole or puncture and apply pressure to affect a
good bond between the two pieces.

within 1 hour or less. This can be done in the field. However,
you would not want to transport the stainless steel molds and
large plastic neck plates that make seal replacements easy. The
Repair Center is designed to be used at a home base, where
additional storage and work space is available.
The instructions for seal replacement come with both the Field

2. Testing the SROB Shell O.S. Systems, Inc. – SROB/SRBEC Drysuits - Use and Care Manual (rev. 8/1/08)
(surface water rescue drysuits- waterproof / breathable)
Page 14 of 19
To test an SROB Drysuit, first fully close the relief zipper.
Then turn the SROB inside out and reach through the neck to fully
close the front entry zipper.
There are two basic methods of closing off the wrist and neck
seals, plug and secure, or fold and clamp. To plug and secure,
insert two small cans, or sand filled bottles (cups filled with
sand and sealed with duct tape work well) into the wrist seals.
One of these plugs should have an air connection so that it will
allow air from a compressor or HP air cylinder to inflate the
suit. Use one larger can to fill the neck seal. Secure these
plugs with stretch Velcro, strong rubber bands/tubes such as
surgical tubing, etc. to keep air from escaping from around the
seals.
The other method for closing off the seals is to fold the ends of
the seals over and clamp them off with some form of clamps that
are strong enough to hold the pressure, but soft enough to not
puncture the seals themselves. Again, you must have a method of
inflating air into the SROB.
Lay the suit (inside out with the front zipper facing up) on a
large worktable. Fill the suit just to the point where the neck
seal just barely starts to bulge out (the suit will feel somewhat
rigid).
With a sponge or spray bottle, apply a soapy water solution to the
entire suit while working on an area no larger that 12 inches by
12 inches. DO NOT become distracted while looking for leaks!!!!
Mark any holes or punctures.
3. Repairing Punctures and Holes Once you have located the hole, puncture, or seam leak, patch the
hole in the same way described above in the Field Repair Section.
4. Replace Wrist Seals Pull the Wrist Wraps up the sleeve to expose the wrist seal.
Using extremely sharp scissors (trauma sheers), trim the old wrist
seal off, even with the end of the fabric. Leave the 1" band of
latex remaining still glued to the fabric sleeve of the SROB.
Insert the squeeze style stainless steel Wrist Repair Mold, larger
end first, into the wrist opening. Leave about 1.50 inches of
metal mold showing out the end of the sleeve.
You will want to keep the sleeve secure and stationary while you
are working on it. Cut off a length of duck tape 1.50 inches

long. Cut that piece lengthwise so that you will have two pieces
approximately 1.00 x 1.50 inches. Roll each piece length wise to
create a small tube that has adhesive all around the outside. You
will want at least three of these duct tape tubes to place on the
mold, and under the sleeve fabric, at even points near the
furthermost edge of the sleeve. Leave some of each of the tubes
sticking out past the sleeve, so that you can use these protruding
edges to secure the new wrist seal that you will be installing on
the sleeve.
Turn a new wrist seal inside out and install it over the tool
while pulling the edge of the new wrist seal even with the edge of
the band of old wrist seal that is still attached to the material.
Press the new latex seal against the protruding pieces of duck
tape. Roll the edge of the new wrist seal up, fully exposing the
remaining band of the old rubber wrist seal.
Wipe the surfaces to be glued on both the old and the new wrist
seals with a clean absorbent material and MEK. Apply one coat of
PB-300 adhesive to both seals and wait 3 minutes. Apply a second
coat PB-300 to both seals and wait 2 minutes. Insert the flat
wooden applicator into the folded area of the new seal and gently
break the bond of any adhesive that overlapped when you were
applying the PB-300.
Now "walk" the new seal over the original seal area so that it
exactly overlays the still glued band of the old wrist seal.
Press the new seal firmly using your fingers. Allow the suit to
set up and cure for 2 hours, longer is better.
5. Replacing the Neck Seal Unzip the Neck Wrap. Using extremely sharp scissors (trauma
sheers), trim the old neck seal off, even with the end of the
MICRO fabric neck hole. Leave the 1" band of the old neck seal
that is glued to the MICRO fabric. Turn the suit inside out to
expose the neck seal.
If possible, attach the Repair Neck Plate on the end of some clean
box or bucket, like a 5 gallon pickle bucket, to raise it up and
let the SROB fall gently down. This will better expose the neck
area for working.
Place the SROB, inside out, over this Repair Neck Plate and
bucket, letting the fabric hang down. Center the neck hole of the
SROB on the Repair Neck Plate and pull the material tight. Clamp
or weight the SROB to hold the MICRO fabric against the Neck
Plate.

The original neck seal (what is left after trimming) should be
centered on the plate, with the rubber facing up. Wipe the top of
the base of the new neck seal, and the exposed band of rubber on
the old neck seal, with MEK. Wipe both dry with a clean (lint
free) cloth. Apply one coat of PB-300 adhesive to the original
and new neck seal, where new seal will overlay the original seal.
Wait for 3 minutes, and apply a second coat of PB-300 adhesive to
the same two parts. Let them sit for 2 minutes. If the PB-300
dries a little too much, simply apply an additional light coat and
then install.
Install the new seal over the original seal using the edges of the
two seals for alignment. Press the new seal firmly using your
fingers. Allow the PB-300 to dry and cure suit for at least two
hours. Longer is better.
