HSN (HNBR) 80 568-046

Part number HSN80046 is an AS568-046 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 4.239 in (107.67 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.379 in (111.23 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, oil resistance of nitrile with substantially better heat capability. This material stands up to sour gas and amine inhibitors, heat and oxidation, and ozone and weathering. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Exposure to ketones or strong oxidizing acids will shorten service life.

Common environments for this compound include engine timing systems, heavy-duty powertrain, and oilfield and downhole equipment.

HSN80046 ships individually. Nominal inside diameter is listed as 4 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
