568-144 GREEN HNBR (HSN) 70 ORINGS

Part number HS70144 is an AS568-144 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.487 in (63.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.693 in (68.4 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, oil resistance of nitrile with substantially better heat capability. The compound resists modern refrigerants, petroleum oils and fuels, and sour gas and amine inhibitors. 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 ketones or chlorinated hydrocarbons are present.

Typical settings include automotive air conditioning, oilfield and downhole equipment, and heavy-duty powertrain.
