1, used for compression dynamic sealing, the start-up friction resistance.
2, dynamic sealing is difficult to achieve no leakage, only to control its leakage does not exceed the specified permissible value.
3, in the pneumatic and hydraulic sealing process, need to add lubricant to prevent wear and tear. In some occasions often need to add dust, protective retaining ring.
4, the pair of matching parts (such as sports surfaces, grooves, gaps, etc.) of the processing size and accuracy requirements.

According to the O-shaped rubber sealing ring and the relative motion of the sealed device, can be divided into static sealing O-ring, reciprocating sealing O-ring, rotary sealing O-ring. According to the sealing structure, can be divided into radial sealing and axial sealing two types of O-ring. Manufacturing O-shaped rubber sealing ring material is mainly synthetic rubber. According to the working temperature, contact medium, the pressure of different, in the choice of rubber is also different.
