568-241 GREEN HNBR (HSN) 70 ORINGS

Part number HS70241 is an AS568-241 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 3.859 in (98.02 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.137 in (105.08 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to modern refrigerants, heat and oxidation, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in chlorinated hydrocarbons or esters.

Common environments for this compound include commercial refrigeration, engine timing systems, and oilfield and downhole equipment.
