568-102 HSN90 DURO ORINGS

HSN90102 is an AS568-102 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 0.049 in (1.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.255 in (6.48 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against ozone and weathering, modern refrigerants, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or esters.

You will find this material specified across heavy-duty powertrain, commercial refrigeration, and oilfield and downhole equipment.

Stocked as HSN90102 and sold individually. Nominal inside diameter is listed as 1/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
