SI Tech - Silicone Wrist Seal Silicone Wrist Seals are constructed from hypoallergenicic silicone that have 40 % better stretch and offer enhanced comfort compared to latex seals. Divers with latex allergies can dive carefree, knowing that the seals are non-allergenic. The seals are durable and resistant to degradation by UV light, ozone or chemicals. The 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. Note: Silicone seals can not be glued to the suit and must be installed with a Modular Quick Change Solution such as the Slaggo Flex Ring System Wrist seals are sold by piece (not pairs).

Advice on Silicone Seals: Even though silicone seals are better in many way than regular latex seals they still must be handled with care. Please handle them 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 talcum, on a regular basis to minimize frictional strain on the seal and for personal comfort. When trimming seals, use sharp scissors. Cut edges should be as smooth and straight as possible. Do not trim across trim lines. Avoid sharp edges.
