Reed RG26 Series Roll Groover
Description and Specifications
Description
The Reed RG26S Roll Groover is designed to form standard
rolled grooves in steel, stainless steel, PVC, and aluminum
pipe in 2-6” schedule 10, and 2-3” schedule 40.
The Reed RG26CU Roll Groover (discontinued) is designed
to form standard rolled grooves in 2” to 6” copper tubing.
The groove is formed by a groove roll which is fed into the
pipe wall. The pipe is supported by a drive roll, which is relieved to permit pipe wall deformation. The formed grooves
comply with the specifications required for mechanical
coupling systems. The only adjustment required is for the
depth of the groove.
Designed for ease of use and portability, the RG26 Series
Roll Groover provides a practical solution for manual on-site
and in-place roll grooving.

(1) Operator’s Manual
If incomplete, contact your Reed Distributor or Reed
Manufacturing Company.
For satisfactory tool operation, the following tube/pipe
preparation tips should be carefully observed:
1. Tube/pipe must be square cut. Do not use a cutting torch.
Note: When adjusting for roll groover depth, the trial
groove pipe should not have a large burr protruding
inward. Use a suitable tool for deburring the pipe or
tubing. After the groove depth has been set, deburring
of the pipe is not required.
2. The end of the tube/pipe, both inside and out, should
be cleaned of coarse scale, dirt or other materials which
might interfere with or damage the grooving rolls or
distort the groove. Large weld beads are to be ground
to permit smooth rolling operation.
The RG26 is an orbital roll grooving tool which rotates
around a pipe held stationary. The pipe may be held in a
pipe vise during grooving. The RG26 also grooves piping
in a depressurized, in-place piping system.
Pipe Vise Set-Up
The choice of grooving location in the shop or field should
take into account the following factors:
• Pipe handling requirements
• Working space requirements for the tool and pipe
• Anchoring requirements for the pipe vise
Procedure
1. Securely mount pipe vise (chain type) on a secure stand
or workbench. Pipe vise should be mounted flush with or
overhang the edge of the stand or workbench so, when
the tool is mounted on the pipe, the tool will rotate freely
around the pipe and not be obstructed by the bench or
stand.
2. Secure pipe in pipe
vise, anchored to
hold securely the
weight of the tool
(21 lbs.) Position
the pipe to overhang the pipe vise
approximately 5 12” so the tool can
rotate in an unobstructed manner.
(See Fig. 1.)
Fig. 1. Pipe Set-up

0215-50356
RG26 Series Roll Groover
Groove-In-Place Set-Up
Previously installed piping may be grooved with the RG26,
providing the piping is securely supported.
NOTE: Pipe hangers must be able to accommodate the
weight of the 21 lb. (9.55 kg) RG26 plus the manual effort
to operate the tool (approximately 20 ft.-lb. torque) during
grooving.
WARNING
Piping systems must always be depressurized and
drained before attempting disassembly.
Failure to do so could result in serious injury, property
damage, joint leakage or joint separation.
Mounting Tool
1. Retract the upper roller fully by turning the brass feed
nut counterclockwise.
2. With the hex drive nut down, insert the nose of the body
into the pipe end. Push the tool onto the pipe until the
pipe end stops rest against the pipe end. (See Fig 2.)
3. Draw rolls together by turning the brass feed nut clockwise. Continue tightening until the grooving rolls are in
light, but firm contact with the pipe.
Operator’s Manual
Adjusting Groove Depth
The Depth Stop Collars must be adjusted for each tube/
pipe size or change in wall thickness. Groove diameter,
identified as the “C” dimension for each tube/pipe size, is
listed under Standard Roll Groove Specifications - Steel and
Other IPS Pipe. For convenience, a “C” Diameter Chart for
the most common pipe sizes is also on the tool.
1. Unlock the depth stop collars by turning them in opposite
directions until they are separated.
2. Locate the groove depth gauge attached to the tool
which is identified with the pipe size to be grooved. Turn
the depth stop collar, closest to the trunnion, until the
distance between the collar and the top of the trunnion
is equal to the groove depth gauge thickness. Use the
groove depth gauge like a feeler gauge. (See Figure 3.)
Fig. 3. Setting Gauge Depth
3. Turn the second collar until both are locked firmly against
one another, maintaining the gap set with the feeler
gauge. Replace the depth gauges back into the holder.
4. Prepare a trial groove by tightening the brass feed nut
the recommended turn increment, and then by turning
the crank nut clockwise until the roll groover has made
one full revolution around the pipe. (See Fig. 4.)
Fig. 2. Tool Insertion

5. Continue turning the feed nut and cranking the tool around
the pipe. Once the jam nuts rest against the trunnion,
continue to crank the tool around for one more revolution. (See Fig. 5.)
Operator’s Manual
7. If groove diameter (“C” dimension) is not within tolerance, adjust the depth stop collars to obtain the proper
dimension. To adjust for a smaller groove diameter, turn
the depth stop collars counterclockwise. To adjust for a
bigger groove diameter, turn collars clockwise. A quarter
turn either way will change the groove diameter by .017”
(.068” per full turn).
8. Prepare another trial groove and check the groove diameter again. Repeat Steps 6 and 7 until groove diameter
is within specification.
Grooving Operation
NOTE: Reed RG26 tool is designed only for roll grooving
tube/pipe of the appropriate sizes. Grooving of tube/pipe
other than that recommended may not produce grooves of
proper tube/pipe end configuration or groove dimensions
necessary for joining.
Before Grooving:
Fig. 5. Turning crank handle
Note: Trial groove pipe should be deburred for best results.
A burr on the inside of the pipe will raise the pipe away from
the drive shaft, causing inaccurate set-up adjustment. After
proper groove depth has been verified by the trial groove,
deburring of the following pipes is not required. See Step
1 of “Tube/Pipe Preparation”
6. After a trial groove is prepared and the tool is removed
from the pipe, carefully check the groove diameter (“C”
dimension), a charted under Standard Roll Groove Specifications - Steel and Other IPS Pipe, page 8, and Drawn
Copper Tubing Groove Specifications, page 9. The “C”
dimension is best checked with a pipe tape. It may also
be checked with a dial caliper or narrow land micrometer
at two locations, 90° apart, around the groove. The average reading must equal the required Groove Diameter.
• Review Safety Precautions before operating the tool.
• Check to be certain tube/pipe has been prepared
properly as detailed in Tube/Pipe Preparation.
• Check to be certain pipe is properly supported as
detailed in Pipe Set-Up.
• Check to be certain the tool is properly mounted on the pipe. See Mounting Tool.
• Check to be certain the depth stop collar is adjusted
correctly. See Adjusting Groove Depth.
CAUTION
The “C” Dimension (groove diameter) must always
conform to specifications under Standard Roll Groove
Specifications, page 9, to ensure proper joint performance. Failure to do so could result in personal injury,
property damage, improper installation, joint leakage
or joint failure.

point, the brass feed nut can no longer be tightened.
Crank the tool at least one more full turn around the tube/
pipe after full groove depth is achieved.
1. Advance the feed by turning the feed nut clockwise by the amount show in Table 1. Feed rates for the RG26 vary depending on material and pipe wall thickness.
5. After dismounting tool from pipe (see below), check
groove depth to ensure groove meets groove depth specification. NOTE: Groove Diameter should be correct for
the diameter and wall thickness of tube/pipe for which it
was set under Groove Diameter Stop Setting procedures.
Groove diameter should be checked periodically and
adjusted as necessary.

2. Lubrication:
a) After approximately eight hours of operation, grease the
bearings at the three grease fittings on the tool. Use a
No. 2 EP Lithium base grease.
b) Weekly apply a light oil (SAE 10W-30 or equivalent) to
the threads where the feed screw passes through the
feed nut. Also, oil should be applied to the shoulder bolts
which hold the roll arm to the body, the feed screw to the
roll arm, and at the trunnion pivots.
Table 1 - Feed Rates
Note: Over-tightening (overfeeding) will result in shortened
bearing life and other tool damage. Over or under-tightening
could result in the tool “walking” off the pipe and eventually
becoming disengaged from the pipe.
2. Place the ratcheting crank handle onto the drive hex.
Crank the drive hex nut clockwise until the tool travels
one full turn around the tube/pipe.
3. Advance the feed by turning the brass feed nut clockwise
by the amount show in Table 1. Crank the tool another
full turn around the pipe.
4. Continue grooving by advancing the feed (Table 1) and
cranking the groover around the tube/pipe until the depth
stop collar comes in contact with the trunnion. At this
