This o-ring is supplied in AS568-373 green HNBR (Hydrogenated Nitrile) 90 Shore A built to an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm), catalogued under part number HSN90373. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists sour gas and amine inhibitors, modern refrigerants, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is valued for improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

You will find this material specified across heavy-duty powertrain, engine timing systems, and oilfield and downhole equipment.
