HSN (HNBR) 80 568-171

Part number HSN80171 is an AS568-171 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 7.987 in (202.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.193 in (208.1 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

HNBR (Hydrogenated Nitrile) delivers strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. This material stands up to heat and oxidation, petroleum oils and fuels, and ozone and weathering. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

You will find this material specified across heavy-duty powertrain, commercial refrigeration, and engine timing systems.

Stocked as HSN80171 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
