Rubber ring

The rubber sealing ring shall have good sealing performance within the working pressure and certain temperature range, and can automatically improve the sealing performance with the increase of pressure.

The friction between the sealing ring device and the moving parts shall be small and the friction coefficient shall be stable.

The sealing ring has strong corrosion resistance, not easy to aging, long service life and good wear resistance. It can be automatically compensated to a certain extent after wear.

The utility model has the advantages of simple structure, convenient use and maintenance, and longer service life of the sealing ring.
