568-123 GREEN HNBR (HSN) 70 ORINGS

Part number HS70123 is an AS568-123 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.174 in (29.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.38 in (35.05 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. This material stands up to sour gas and amine inhibitors, heat and oxidation, and petroleum oils and fuels. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. It should not be specified for service in ketones or chlorinated hydrocarbons.

Common environments for this compound include automotive air conditioning, oilfield and downhole equipment, and commercial refrigeration.
