HNBR (Hydrogenated Nitrile) is specified here for oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. It resists modern refrigerants, heat and oxidation, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with strong oxidizing acids or chlorinated hydrocarbons.

Common environments for this compound include oilfield and downhole equipment, engine timing systems, and commercial refrigeration.
