This material stands up to sour gas and amine inhibitors, ozone and weathering, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is known for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with ketones or chlorinated hydrocarbons.

It sees regular use in engine timing systems, commercial refrigeration, and oilfield and downhole equipment.
