1.Rubber flat washers: easily deformed, not hard to tighten, but with poor pressure and temperature resistance; only suitable for low-pressure and low-temperature environments...

2.Rubber O-rings: With a circular cross-section shape, they exhibit a certain self-tightening effect, offering better sealing performance than flat washers and requiring less clamping force.

3.Plastic Flat Washers: The characteristics of plastic include good resistance to corrosion, but most plastics have poor heat resistance. Polytetrafluoroethylene (PTFE) is the crown of plastics, and not only...

PTFE Sealing Washers: Designed to maximize the benefits of PTFE while compensating for its lower elasticity.
