O-ring is a kind of rubber seal with a circular cross section. Because its cross section is O-shaped, it is called O-ring seal, also called O-ring. It began to appear in the mid-19th century when it was used as a sealing element for steam engine cylinders. Because of its low cost, simple manufacturing, reliable functionality, and simple installation requirements, O-rings are the most common mechanical design for sealing. O-rings are subjected to pressures of tens of megapascals (thousand pounds). O-rings can be used in static applications or in dynamic applications where there is relative motion between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.
O-type rubber sealing ring manufacturers to introduce to you: O-ring specifications and models mainly include UHSO ring specifications, UHPO ring specifications, UNO ring specifications, DHO ring specifications, piston rod O-ring specifications, high temperature O-rings , high pressure O-ring, corrosion-resistant O-ring, wear-resistant O-ring.
The standard of O-ring is mainly GB 1235-76, GB3452.1-92; Japanese standard P TYPE, G TYPE, S TYPE, SS/V TYPE, F TYPE; American standard AS568, British standard series; European standard series
