The O-ring is suitable to be installed on various mechanical equipment, and plays a sealing role in the static or moving state under the 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 seal and reciprocating seal. When used for rotary motion sealing, it is limited to low-speed rotary sealing device.
The O-ring is generally installed in the groove with rectangular section on the outer circle or inner circle to play a sealing role.
The O-ring still plays a good sealing and shock absorption role in the environment of oil resistance, acid and alkali resistance, wear, chemical erosion and so on. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission systems
