Assorted Teflon Crystal Gasket Replacement

Restore proper crystal fitment and support your watch case’s water resistance with these replacement PTFE crystal gaskets, available in a wide selection of sizes for different watch cases and crystal profiles.

Manufactured from durable polytetrafluoroethylene (PTFE), each gasket provides stable compression, low friction, and excellent resistance to moisture, chemicals, and long-term wear. It fits between the crystal and watch case, helping maintain correct alignment and secure crystal installation when fitted properly.

Ideal for replacing worn, hardened, compressed, distorted, or damaged crystal gaskets during watch servicing and restoration. Please measure the original gasket and confirm its inner diameter, outer diameter, height, and profile before ordering.

Professional installation is recommended. Water resistance is not guaranteed and should be verified through appropriate pressure testing after installation.
