Nitrile butadiene rubber (NBR Oring) is a copolymer of
acrylonitrile and butadiene, also known as nitrile butadiene rubber
or
butadiene rubber. Because of its good tolerance to petroleum-based
fuels and lubricating oil, NBR sealing ring is the best oil
resistance rubber material, and relatively low price, is one of the
most commonly used sealing elastomers.
