568-332 GREEN HNBR (HSN) 70 ORINGS

This o-ring is supplied in AS568-332 green HNBR (Hydrogenated Nitrile) 70 Shore A built to an inside diameter of 2.35 in (59.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.77 in (70.36 mm), catalogued under part number HS70332. It compresses into its gland to block fluid or gas migration across a joint.

This material stands up to sour gas and amine inhibitors, modern refrigerants, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is specified for the oil resistance of nitrile with substantially better heat capability, improved ozone and weathering resistance over standard nitrile. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

Typical settings include automotive air conditioning, heavy-duty powertrain, and oilfield and downhole equipment.

This item is sold individually under part number HS70332. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
