HSN (HNBR) 80 568-472

The HSN80472 is an AS568-472 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 22.94 in (582.68 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 23.49 in (596.65 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against heat and oxidation, petroleum oils and fuels, and ozone and weathering. HNBR (Hydrogenated Nitrile) is widely chosen for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or chlorinated hydrocarbons.

Common environments for this compound include automotive air conditioning, oilfield and downhole equipment, and commercial refrigeration.

HSN80472 ships individually. Nominal inside diameter is listed as 23 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
