What are the scope of application of O-ring

O-rings are suitable for being installed on various mechanical equipment, under the specified temperature, pressure, and different liquid and gaseous media, to play a sealing role in static or moving states. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction 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 seals, it is limited to low-speed rotary seals.
The O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role. O-rings still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali resistance, grinding, and chemical erosion. Therefore, O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.
