The O-ring sealing ring is suitable for installing on various mechanical equipment, and plays a sealing role in a static on moving state at the specified temperature, pressure, and different liquid and gas media. Various types of sealing components are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery,and various instruments. The O-ring sealing ring is mainly used for static sealing and reciprocating motion sealing. When used for rotating motion sealing, it is limited to low-speed rotary sealing devices. The O-ring sealing ring is generally installed in a groove with a rectangulan cross-section of the outer or inner circle to play a sealing role The O-type sealing ring still plays a good role in sealing and shock absorption in oil resistance,acid and alkali grinding, chemical erosion and other environments. Therefore, the O-ring seal ring is the most widely used seal in hydraulic and pneumatic transmission systems.
