Part number HS70904 is an AS568-904 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.351 in (8.92 mm), a cross section of 0.072 in (1.83 mm), and an outside diameter of 0.495 in (12.57 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

HNBR (Hydrogenated Nitrile) is widely chosen for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. The compound resists ozone and weathering, sour gas and amine inhibitors, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

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