O-ring is a rubber seal with a circular cross section. Because its cross section is O-shaped, it is called an O-ring and is also called an O-ring. It first appeared in the mid-19th century, when it was used as a sealing element for steam engine cylinders.
Introduction of O-ring
O-ring specifications 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-rings, and corrosion-resistant O-rings Ring, wear-resistant O-ring.
Because of its low price, simple manufacturing, reliable function, and simple installation requirements, the O-ring is the most common mechanical design for sealing. O-rings withstand tens of megapascals (thousand pounds). O-rings can be used in static applications or in dynamic applications with relative movement between components, such as rotary pump shafts and hydraulic cylinder pistons.
