HSN (HNBR) 80 568-332

HSN80332 is an AS568-332 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 2.35 in (59.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.77 in (70.36 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is widely chosen for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. It resists heat and oxidation, modern refrigerants, and petroleum oils and fuels. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or esters will shorten service life.

You will find this material specified across engine timing systems, heavy-duty powertrain, and oilfield and downhole equipment.

Reference part number HSN80332 when ordering; the item is sold individually. Unit weight is approximately 5.856 g and nominal inside diameter is listed as 2 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
