Nitrile (NBR) Rubber
Nitrile (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil. It also offers strong resistance to heat aging - often a key advantage over natural rubber.
Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.
