Silicone Seals Manual

waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 SILICONE ADVANTAGES Never try to glue or patch a broken silicone seal! After a dive check and clean the seal for tears or damage, especially in the fold where it comes out from the oval stiff ring. The seals are glide treated but it is advisable to use unscented talc powder to enhance a trouble-­‐
free donning. Silicone seals were introduced to the market in 2009 by Waterproof. Silicone Seals have no chemical or environmental sensitivity and they have approximately 40% better stretch than latex seals. This elasticity makes donning the suit much easier and it seals with your skin more effectively. Since the pressure is lower on the wrists your hands will stay warmer. The comfort really is enhanced during long technical dives and decompression stops. A few of the features are listed below: TRIMMING SEALS When trimming seals, use sharp scissors. Cut edges should be as smooth and straight as possible. Make sure there are absolutely no pointed cuts into the seal. Do not trim across trim lines. 100 % UV and Ozone resistant Very stretchable Enhanced durability No latex allergy Easy donning and doffing Extremely fast mounting Interior Glide Coating Safety Ridge THE PARTS GENERAL ADVICE Even though silicone seals are better in many ways than regular latex seals they still must be handled with care. Overstretching, sharp objects and poor trimming can cause your seal to tear. Even if the silicone seals have more stretch than latex seals, do not stretch the seal more than required. Assist yourself with a free hand when pulling the seals over your head or hands -­‐ both for the seal and your comfort. Avoid contact with sharp objects, like finger nails or rings, when handling seals. Use a product such as unscented talc on a regular basis to minimize frictional strain on the seal and for personal comfort. The ISS wrist seal consists of three parts. 1. PU ring (Polyurethane ring) which is glued to the suit. This ring is soft. 2. Oval Stiff Ring is the inner plastic ring that holds the Silicone Seal. 3. The Silicone Seal. 1 2 3 MAINTENANCE Silicone Seals are virtually maintenance free, but there are a couple of things to think of. 2 waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 REPLACING A WRISTSEAL 1. Fold up the zipper cover and remove the neoprene cuff. 2. Hold the ring system with both hands with the seal towards you. 3a. Carefully insert the tool between the PU-­‐
ring and the Stiff ring and bend upwards until the ring pops out. Bend carefully without twisting the tool. If it is too hard to get the tool in position at the “short side” of the ring, start at the recess and slide the tool to the side. 4. Clean the inner PU-­‐ring and the Oval stiff ring thoroughly. 3. Place both thumbs in the groove and push/bend the soft PU-­‐ring upwards/ backwards towards arm and at the same time push down the back end of the ring with your other fingers. Push hard until the inner stiff ring loosens. 1 2 These images illustrate two different ways of positioning the seal depending on the design and fabric of the Drysuit and how the PU-­‐Ring is attached into the Drysuit. One of these mounting alternatives will work better than the other. It is important to try assembling the components both ways to see which one works best. The suit comes from the factory with seals in position 1. If leakage occurs after changing a seal or ring, try mounting the seal in position 2. If you find it too difficult to dismount the ring by hand you can use a standard plastic bike tire removal tool. 3 waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 7. Align the oval stiff ring to the alignment mark on the suit and carefully fit the seal in the suit. 5. Mount the new seal by placing the ridge of the seal in the groove with the glide coated side out. 8. It is very important that the Seal doesn’t get any wrinkles when mounting it in the suit. Push the seal slowly and carefully little by little until it stops. Then push the last bit until you hear a clicking sound. Again, it should slide very easily into position, if not, use more lubricant. 6. Add waterbased lubricant on both the seal and inside the suit PU-­‐ring. It is better to use too much than too little. It should slide easily. 4 waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 3. When the tool has reached the bottom of the groove, it´s time to use the tool to bend up the Lock Ring from the groove. 9. Grab the end of the seal as the image shows and pull it gently away from the joint to ensure that it is seated properly. NECKSEAL DETACHMENT Make sure you have the SI Tech Neck Tite Tool. 1. Press the Neck Tite Tool towards the bottom of the groove in the PU-­‐ring. 4. Press up the Lock Ring from the groove. 5. When you have successfully released the Lock Ring you can use your fingers to pull the seal and Lock Ring out of its position. If the same seal shall be used again, please be careful and check for damages on the seal. 2. Press the tool in the direction of the arrow and force the groove in the PU-­‐ring to ”open up” and start releasing the Lock Ring. 5 waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 NECKSEAL ATTACHMENT 3. Put the Neck Tite Tool in position as image displays. By applying force, press the Lock Ring down into the tapered groove of the PU-­‐Ring so that the Lock Ring enters the groove and locks into position. Use a flat surface when performing this operation. 1. Place the Lock Ring on the inside of the seal. Ensure that approx. 0.5” of the seal is pulled over the Lock Ring. 2. Put the seal in position over the PU-­‐Ring (mounted on your drysuit) with the Lock Ring on top of the tapered groove in the PU-­‐Ring. Make sure that the bellow of the Neckseal faces the back of the suit. 4. Push the Neck Tite Tool forward along the Lock Ring until all of it has been forced into the groove in the PU-­‐Ring. 6 waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 gently away from the joint to ensure that it is seated properly. Do not use excessive force! Simulate the same force as used when donning suit. RECOMMENDATIONS • Make pre-­‐dive checks at all times. • Always check seals for scratching and pinching. • Always check your Neck Tite Tool for sharp edges that might occur over time. • Avoid exposing the seals to direct sunlight. • Always clean sand and dirt from your seal. • Use unscented talc on seals to extend the lifespan. • Remove seals from your suit during long periods of storage. 5. Ensure that the excess part of the seal is similar throughout the entire dressing. We recommend between: 0.5”-­‐0.75”. 6. Check that the Lock Ring is in position by following the groove 360°. 7. After completing the seal attachment section, perform a security check: Grab the end of the seal as the image shows and pull it 7 waterproof— Waterproof Drysuit Manual 2013-­‐03-­‐08 CONTACT
