HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, strong resistance to rapid gas decompression. The compound resists modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving esters or strong oxidizing acids call for a different compound.

Common environments for this compound include engine timing systems, heavy-duty powertrain, and automotive air conditioning.
