Nitrile, also known as Buna-N, is available in calendared sheet, o-rings, and (butadiene-acrylonitrile) oil seals. Available in commercial and high grade compounds.

+ Excellent resistance to oils, solvents and fuels. Resistant to a broader range of aromatic hydrocarbons than neoprene. Nitrile may be blended with SBR to achieve an economically priced moderate oil resistant (MOR) sheet.

Materials with less nitrile content may swell in extreme oil applications or in contact with fuels and solvents. Nitrile content levels can vary widely. Where oil or fuel resistance is required, MIL SPEC or ASTM callout may be specified.
