APG stocks the HS70333, an AS568-333 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.475 in (62.87 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.895 in (73.53 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
This material stands up to petroleum oils and fuels, heat and oxidation, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C).
It sees regular use in heavy-duty powertrain, automotive air conditioning, and oilfield and downhole equipment.
HS70333 ships individually. Nominal inside diameter is listed as 2 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
