568-392 GREEN HNBR (HSN) 70 ORINGS

Part number HS70392 is an AS568-392 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) delivers improved ozone and weathering resistance over standard nitrile, strong resistance to rapid gas decompression. This material stands up to sour gas and amine inhibitors, petroleum oils and fuels, and modern refrigerants. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Exposure to esters or chlorinated hydrocarbons will shorten service life.

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