568-380 HSN90 DURO ORINGS

The HSN90380 is an AS568-380 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 11.475 in (291.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 11.895 in (302.13 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) is specified for strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. Expect good resistance to petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or chlorinated hydrocarbons.

Common environments for this compound include heavy-duty powertrain, commercial refrigeration, and automotive air conditioning.

This item is sold individually under part number HSN90380. Nominal inside diameter is listed as 11 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
