An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) offers strong resistance to rapid gas decompression, excellent abrasion and tear strength. The material holds up against modern refrigerants, heat and oxidation, and sour gas and amine inhibitors. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C).

You will find this material specified across commercial refrigeration, engine timing systems, and heavy-duty powertrain.
