The Waterproof silicone neck seal is a replacement for compatible mechanical neck-seal systems, including the matching SI TECH Neck Tite arrangement. Its flexible bellows profile accommodates neck movement while the inner sealing area sits against the skin.
Features and benefits
- Stretch silicone: allows the head to pass through during dressing and then returns to a close-fitting neck shape.
- Bellows profile: gives the neck section room to move as you turn and look around.
- Interior glide coating: reduces friction when dressing, helping the seal pass over the skin more smoothly.
- Retaining ridge: locates the seal in the correct mechanical ring interface so it can be replaced without gluing it to the suit.

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. Silicone is mechanically retained and is not a direct glue-in replacement for a latex neck seal.
Care
Handle seals with clean hands and remove sharp jewellery before dressing. Inspect for cuts or damage before use, rinse as directed, and follow the seal system’s instructions for sizing, fitting and care.
