HSN (HNBR) 80 568-338

This o-ring is supplied in AS568-338 green HNBR (Hydrogenated Nitrile) 80 Shore A with an inside diameter of 3.1 in (78.74 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.52 in (89.41 mm), catalogued under part number HSN80338. It delivers dependable bidirectional sealing in a compact groove envelope.

As a material, HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability, improved ozone and weathering resistance over standard nitrile. This material stands up to sour gas and amine inhibitors, petroleum oils and fuels, and heat and oxidation. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Applications involving chlorinated hydrocarbons or esters call for a different compound.

You will find this material specified across heavy-duty powertrain, automotive air conditioning, and oilfield and downhole equipment.

HSN80338 ships individually. Unit weight is approximately 7.551 g and nominal inside diameter is listed as 3 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
