568-120 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70120, an AS568-120 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to sour gas and amine inhibitors, heat and oxidation, and petroleum oils and fuels. That behavior comes from the compound itself: 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). Verify compatibility before use with chlorinated hydrocarbons or esters.

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

Stocked as HS70120 and sold individually. Nominal inside diameter is listed as 1 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
