HSN (HNBR) 80 568-467

This o-ring is supplied in AS568-467 green HNBR (Hydrogenated Nitrile) 80 Shore A measuring an inside diameter of 18.955 in (481.46 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 19.505 in (495.43 mm), catalogued under part number HSN80467. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for improved ozone and weathering resistance over standard nitrile, strong resistance to rapid gas decompression. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in chlorinated hydrocarbons or strong oxidizing acids.

You will find this material specified across automotive air conditioning, engine timing systems, and heavy-duty powertrain.

This item is sold individually under part number HSN80467. As always, verify media compatibility and operating conditions against the requirements of your specific application.
