HSN (HNBR) 80 568-362

Part number HSN80362 is an AS568-362 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 6.225 in (158.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.645 in (168.78 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to petroleum oils and fuels, sour gas and amine inhibitors, and modern refrigerants. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where esters or strong oxidizing acids are present.

You will find this material specified across automotive air conditioning, commercial refrigeration, and oilfield and downhole equipment.
