HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. The compound resists heat and oxidation, ozone and weathering, and modern refrigerants. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to ketones or esters will shorten service life.

Typical settings include automotive air conditioning, engine timing systems, and oilfield and downhole equipment.
