Introduction to NBR 90 O Ring
NBR 90 O - rings are made from Nitrile Butadiene Rubber (NBR) with a hardness of 90 on the Shore A scale. NBR is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. The high - hardness NBR 90 O - rings offer excellent resistance to oil, fuel, and other hydrocarbons. They are widely used in automotive, industrial machinery, hydraulic systems, and many other applications where sealing against fluids is crucial. Their high hardness makes them suitable for applications with high - pressure environments, as they can maintain their shape and sealing performance under significant forces.
