O-ring is a kind of rubber ring with circular section. O-ring is one of the most widely used seals in hydraulic and pneumatic systems. O-ring has good sealing performance, which can be used in both static and reciprocating seals; It can not only be used alone, but also is a basic part of many combined sealing devices. If the material is selected properly, it can meet the requirements of various motion conditions, and the working pressure can be increased from 1.333 × 105Pa vacuum to 400MPa high pressure; The temperature range is from - 60 ℃ to 200 ℃.
