HSN (HNBR) 80 568-447

Part number HSN80447 is an AS568-447 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 8.975 in (227.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.525 in (241.94 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, excellent abrasion and tear strength. It resists modern refrigerants, heat and oxidation, and sour gas and amine inhibitors. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Applications involving esters or ketones call for a different compound.

Common environments for this compound include automotive air conditioning, oilfield and downhole equipment, and heavy-duty powertrain.

Reference part number HSN80447 when ordering; the item is sold individually. Nominal inside diameter is listed as 9 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
