HSN (HNBR) 80 568-153

Ordered as HSN80153, this is an AS568-153 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum oils and fuels, sour gas and amine inhibitors, and modern refrigerants. HNBR (Hydrogenated Nitrile) is specified for the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or esters.

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

HSN80153 ships individually. Nominal inside diameter is listed as 3 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
