568-912 HSN90 DURO ORINGS

Part number HSN90912 is an AS568-912 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 0.924 in (23.47 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.156 in (29.36 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. This material stands up to heat and oxidation, petroleum oils and fuels, and sour gas and amine inhibitors. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Applications involving strong oxidizing acids or esters call for a different compound.

Common environments for this compound include engine timing systems, automotive air conditioning, and commercial refrigeration.

This item is sold individually under part number HSN90912. Nominal inside diameter is listed as 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
