HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. The material holds up against ozone and weathering, modern refrigerants, and petroleum oils and fuels. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to esters or ketones will shorten service life.

Maintenance and OEM teams specify it across engine timing systems, heavy-duty powertrain, and automotive air conditioning.
