The principle of O-ring!
O-ring, referred to as O-ring, is a rubber ring with a circular cross-section.
O-ring is the most widely used seal in hydraulic and pneumatic systems. O-ring has good sealing property, can be used for static sealing, also can be used for reciprocating sealing; Not only can be used alone, but also is the basic component of many combined sealing devices.
Its application range is very wide, if the material is selected properly, can meet the requirements of various sports conditions, O-ring has the following characteristics:
1 Small structure size, convenient installation and disassembly.
2 Static and dynamic seals can be used, almost no leakage when used as static seals.
3 The use of a single O-ring, two-way sealing effect.
4 Low dynamic friction resistance.
5 Low price.
