568-131 GREEN HNBR (HSN) 70 ORINGS

Part number HS70131 is an AS568-131 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.674 in (42.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.88 in (47.75 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against petroleum oils and fuels, ozone and weathering, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) delivers strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Applications involving chlorinated hydrocarbons or esters call for a different compound.

Common environments for this compound include oilfield and downhole equipment, heavy-duty powertrain, and commercial refrigeration.

HS70131 ships individually. Nominal inside diameter is listed as 1 11/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
