large size viton o ring seal
O-ring is suitable for being installed on various mechanical equipment, and it can seal in static or moving state under specified temperature, pressure and different liquid and gas media. Various types of sealing elements 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 and meters. O-ring is mainly used for static sealing and reciprocating sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing device. O-ring seals are generally installed in grooves with rectangular cross-section on the outer circle or inner circle to play a sealing role. O-ring still plays a good role in sealing and damping in the environment of resisting oil, acid and alkali, grinding and chemical attack. Therefore, O-ring seal is the most widely used seal in hydraulic and pneumatic transmission system.
