Product Description

O-ring is a rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called O-shaped rubber sealing ring, also called O-ring. It began to appear in the middle of the 19th century, when it was used as a sealing element for steam engine cylinders. Because it is inexpensive, simple to manufacture, reliable in function, and simple to install, O-rings are the most common mechanical design for sealing. The O-ring withstands several tens of megapascals (thousand pounds) of pressure. O-rings can be used in static applications, but also in dynamic applications where there is relative movement between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.
