568-122 GREEN HNBR (HSN) 70 ORINGS

The HS70122 is an AS568-122 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.112 in (28.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.318 in (33.48 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. It resists sour gas and amine inhibitors, heat and oxidation, and modern refrigerants. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C).

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