HSN (HNBR) 80 568-336

Part number HSN80336 is an AS568-336 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 2.85 in (72.39 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.27 in (83.06 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) offers improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. It resists ozone and weathering, petroleum oils and fuels, and modern refrigerants. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

It sees regular use in engine timing systems, automotive air conditioning, and commercial refrigeration.
