HSN (HNBR) 80 568-206

This o-ring is supplied in AS568-206 green HNBR (Hydrogenated Nitrile) 80 Shore A built to an inside diameter of 0.484 in (12.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.762 in (19.35 mm), catalogued under part number HSN80206. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) delivers improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. It resists sour gas and amine inhibitors, ozone and weathering, and modern refrigerants. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving strong oxidizing acids or ketones call for a different compound.

It sees regular use in heavy-duty powertrain, automotive air conditioning, and engine timing systems.
