APG stocks the HS70230, an AS568-230 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.484 in (63.09 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.762 in (70.15 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, long service life in refrigerant and oilfield duty. Expect good resistance to sour gas and amine inhibitors, ozone and weathering, and modern refrigerants. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

Common environments for this compound include heavy-duty powertrain, automotive air conditioning, and commercial refrigeration.

HS70230 ships individually. Nominal inside diameter is listed as 2 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
