HSN (HNBR) 80 568-450

Part number HSN80450 is an AS568-450 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 10.475 in (266.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.025 in (280.04 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where chlorinated hydrocarbons or esters are present.

Typical settings include commercial refrigeration, engine timing systems, and heavy-duty powertrain.

This item is sold individually under part number HSN80450. Nominal inside diameter is listed as 10 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
