This o-ring is supplied in AS568-211 green HNBR (Hydrogenated Nitrile) 70 Shore A built to an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm), catalogued under part number HS70211. It delivers dependable bidirectional sealing in a compact groove envelope.
The compound resists modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is valued for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or ketones will shorten service life.
You will find this material specified across heavy-duty powertrain, engine timing systems, and automotive air conditioning.
Order part number HS70211, sold individually. Unit weight is approximately 1.0097 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
