568-468 HSN90 DURO ORINGS

Ordered as HSN90468, this is an AS568-468 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 19.455 in (494.16 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.005 in (508.13 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to heat and oxidation, petroleum oils and fuels, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) delivers excellent abrasion and tear strength, strong resistance to rapid gas decompression. 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.

You will find this material specified across heavy-duty powertrain, oilfield and downhole equipment, and engine timing systems.
