568-112 HSN90 DURO ORINGS

HSN90112 is an AS568-112 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 0.487 in (12.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.693 in (17.6 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to sour gas and amine inhibitors, petroleum oils and fuels, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. It is not the right choice where esters or chlorinated hydrocarbons are present.

You will find this material specified across heavy-duty powertrain, commercial refrigeration, and automotive air conditioning.

This item is sold individually under part number HSN90112. As always, verify media compatibility and operating conditions against the requirements of your specific application.
