NBR rubber oil seals

The double seal oil seals in NBR rubber generally prevent the leakage of lubricating oil, acting as a sealing gasket. They retain the fluids inside the cylinder and, at the same time, protect against the intrusion of external elements. The double seal and double lip oil seals are formed by an external coating in NBR nitrile rubber which covers a metal insert that makes up the external part and with a sealing lip held by a spring. The WAS type is available with protective lip which acts as a dust seal. Nitrile rubber, NBR, is a synthetic rubber that is well resistant to hydrocarbons and other chemicals, such as animal and vegetable fats. NBR rubber is used in various fields of the automotive industry, the engineering industry and the aeronautical industry. Withstands a wide range of temperatures, from -40 ° C to +100 ° C
