Project details

An O-ring is a rubber sealing ring with a circular cross-section. Due to its O-shaped cross-section, it is called an O-shaped rubber sealing ring, also known as an O-ring. It has the advantages of cheap price, simple manufacturing, reliable function, simple installation requirements, and can withstand pressure of tens of megapascals (thousands of pounds). Therefore, it is widely used in various mechanical seals, such as the shaft of rotary pumps and hydraulic cylinder pistons.

O-rings 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. In addition, the selection of its material is of great significance for its sealing performance and service life, as the performance of the material directly affects the performance of the sealing ring.
