O-shaped rubber ring seal is abbreviated as O-ring, which is a rubber ring with a circular cross-sectional shape. O-rings are the most widely used seals in hydraulic and pneumatic systems. O-ring has good sealing performance and can be used for static sealing and dynamic sealing; O-ring can still play a good sealing and shock absorption effect in oil, acid, alkali, abrasion, chemical erosion and other environments, and can be used alone , Is also a basic part of many combined sealing devices.

O-ring seals are the most widely used seals in hydraulic and pneumatic transmission systems. O-ring seals are suitable for installation on various mechanical equipment, at specified temperatures, pressures, and different liquid and gas media. Play a sealing role in static or moving state. Various types of seals 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. element.

O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. O-rings are generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle for sealing.
