HNBR (Hydrogenated Nitrile) is specified here for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. It resists modern refrigerants, ozone and weathering, and heat and oxidation. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with esters or strong oxidizing acids.

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