This o-ring is supplied in AS568-025 green HNBR (Hydrogenated Nitrile) 80 Shore A measuring an inside diameter of 1.176 in (29.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.316 in (33.43 mm), catalogued under part number HSN80025. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. It resists heat and oxidation, petroleum oils and fuels, and sour gas and amine inhibitors. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Applications involving chlorinated hydrocarbons or ketones call for a different compound.

Typical settings include heavy-duty powertrain, commercial refrigeration, and automotive air conditioning.
