The HSN80252 is an AS568-252 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 5.234 in (132.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.512 in (140 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. It resists sour gas and amine inhibitors, ozone and weathering, and heat and oxidation. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Verify compatibility before use with esters or chlorinated hydrocarbons.

You will find this material specified across heavy-duty powertrain, automotive air conditioning, and oilfield and downhole equipment.
