568-346 HSN90 DURO ORINGS

Part number HSN90346 is an AS568-346 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 4.1 in (104.14 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.52 in (114.81 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. The compound resists ozone and weathering, modern refrigerants, and sour gas and amine inhibitors. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or esters.

Common environments for this compound include heavy-duty powertrain, engine timing systems, and commercial refrigeration.
