Introduction
Featuring an improved composite design, this sealing gasket incorporates a PTFE (polytetrafluoroethylene) outer layer bonded with a rubber core to address leakage issues caused by aging and wear in conventional rubber gaskets. By combining the excellent wear resistance, chemical resistance, and low-friction properties of PTFE with the elasticity and sealing performance of rubber, it provides enhanced sealing capability and extended service life. Suitable for stop valves and various fluid control applications.
