Furthermore, it could be used reliably as movable and immovable seals in the circumstance of Big pressure and high temperature. If reasonable design, o-rings have very long life.

2. O-rings could not only be used for its good sealing performance, but also for ite mechanical performaces, it is being used widely in drive strap, tyre, controlling equipment and vibration absorber. It could be made by many kinds of raw materials, such as NBR, SBR, Silicone, FPM.
