In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) is widely chosen for the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. It resists petroleum oils and fuels, modern refrigerants, and sour gas and amine inhibitors. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C).

Maintenance and OEM teams specify it across automotive air conditioning, oilfield and downhole equipment, and heavy-duty powertrain.
