HSN (HNBR) 80 568-160

The HSN80160 is an AS568-160 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 5.237 in (133.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.443 in (138.25 mm). This 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, long service life in refrigerant and oilfield duty. It resists modern refrigerants, heat and oxidation, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or ketones.

You will find this material specified across automotive air conditioning, engine timing systems, and commercial refrigeration.
