WaterProof HD Silicone Wrist Seal
Waterproof HD silicone wrist seals replace the sealing surfaces in a compatible drysuit wrist-ring system. The flexible silicone stretches over the hand and sits closely around the wrist, making these a useful spare for a suit that uses the matching mechanical interface.
Features and benefits
- Heavy-duty silicone: the HD version prioritises improved tear resistance compared with standard Waterproof silicone seals, with slightly less stretch. It still needs careful handling around fingernails and sharp equipment.
- Mechanical retention: the seal is held by the compatible ring system, allowing replacement without re-gluing the suit-mounted ring.
- Choose the correct size: Small and Standard options accommodate different wrists and fittings. Check the actual seal opening and ring profile, not just the size name.
- Pair supplied: provides replacement seals for both wrists.

Fit and use
Match the part to the exact suit, seal profile and retaining system before ordering. Ask our Hallam team if you need help with sizing or compatibility. These are not the dedicated Flexlock seals and are not a direct glue-in replacement for latex seals.
Gear Care and Washing
Rinse the sealing surfaces and ring components with fresh water after use. Wash skin oils from seals gently using only the suit manufacturer’s approved method, then rinse thoroughly and let them dry in the shade.
Protect silicone, latex and smooth neoprene from fingernails, jewellery and sharp edges. Use only the specified dressing aid or O-ring lubricant for the exact material and ring system. Store clean and dry away from heat, sunlight and ozone sources, and inspect for damage before use.
