Project details

The O-ring seal is a common mechanical design for sealing, named after its O-shaped cross-section. It has various excellent characteristics, such as small size, easy assembly and disassembly, both dynamic and static seals are available, static seals have almost no leakage, single piece use of bidirectional seals, low dynamic friction, low price, etc., so it is widely used in various mechanical equipment.

O-rings can withstand pressures of tens of megapascals (kilopounds) and can be used in static applications or dynamic applications where there is relative motion between components, such as rotating pump shafts and hydraulic cylinder pistons. The selection of its material is of great significance for its sealing performance and service life, and the performance of the material directly affects the service performance of the sealing ring
