  • Fluorine rubber O-ring

    Referred to as FKM or VT O-ring, it has very good oil resistance, high temperature resistance, corrosion resistance, aging resistance and other excellent characteristics.

  • Butadiene O-ring

    Referred to as NBR O-ring, it is a synthetic rubber O-ring made by copolymerization of butadiene and acrylonitrile. It has excellent wear resistance, air tightness and oil resistance.

  • Silicone O-ring

    Referred to as SL ring, it has good electrical insulation, high temperature resistance, non-toxic and tasteless, excellent cold and heat resistance, and antistatic properties.

  • Coated O-ring

    Coated O-ring is a kind of O-ring that shows good non-stick, sliding and moisture resistance after spraying on the surface of rubber O-ring.

  • Rubber sealed loop

    The rubber seal ring can be divided into fluorine rubber, silicon rubber, nitrile rubber, neoprene, EPDM, polytetrafluoroethylene, etc.

  • O-ring

    The English name of O-rings is O-rings, which is a round (O-shaped) cross-section rubber sealing ring, which is generally installed in a groove with a rectangular cross-section on the inner or outer circle for sealing.

  • Coated O-ring

    It is a seal composed of a relatively thick inner core made of relatively thick silicone rubber or fluorine rubber and a relatively thin combination of various outer covering materials such as PTFE/FEP/PFA
