O-ring is a kind of round rubber ring which prevents the leakage of lubricating oil or foreign matters. It is widely used in hydraulic and pneumatic transmission system.
NBR, Silicon rubber, Fluoro rubber
● With good sealing performance under the working pressure and a certain temperature range, the O-ring can automatically improve the sealing performance under the increasing pressure.
● The friction between the O-ring device and the moving parts is very small, and the friction coefficient is stable.
● Strong corrosion resistance, lowest aging, long service life, good wear resistance
● Self compensation to some extent after wear and tear.
