When used in rotary reciprocating seal, only low speed rotary seal device is used. O-ring is usually installed in the groove with rectangular section on the outer circle or inner circle to play a sealing role. The O-ring can still play a good sealing and shock absorption role in the environment of oil resistance, acid and alkali resistance, wear resistance and chemical corrosion resistance. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system.
