Product: Oil resistant China supplier NBR rubber O-ring for auto spare parts What is O-ring? O-rings are usually be used in static and dynamic applications. The function of it is to prevent the fluid or air from in or out from a specific area. O-ring is the most common fluid power seals in industrials. The O type seal ring (O-rings) is a rubber ring with circular section. Because its cross section is O type, it is called the O type rubber seal ring, also known as the O ring. It began to appear in the middle of nineteenth Century when it was used as a sealing element for steam turbine cylinders.Product Details:Materials: Viton rubber, NBR, Butyl rubber, EPDM rubber, SBR, Natural rubber and etc. Other Names: Rubber sealing ring, rubber ring, O-ring, rubber seal.Hardness: Shore A 45 -80Operating temperature: -40 - 200 °CColor: Red, Green, Blue, White, Black,GreyApplication: Oil resistant China supplier NBR rubber O-ring are used in Automobiles, Auto Engines, Marines, Ships, Electronic machines, food machines, Valves and etc. Product Features: - The Viton rubber performs excellent under low and high temperature especially high temperature.
