As a material, HNBR (Hydrogenated Nitrile) is known for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. This material stands up to petroleum oils and fuels, heat and oxidation, and sour gas and amine inhibitors. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or esters.

Maintenance and OEM teams specify it across oilfield and downhole equipment, automotive air conditioning, and commercial refrigeration.
