568-022 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70022, an AS568-022 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 0.989 in (25.12 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.129 in (28.68 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists petroleum oils and fuels, ozone and weathering, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) is widely chosen for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or ketones.

It sees regular use in commercial refrigeration, heavy-duty powertrain, and automotive air conditioning.
