568-430 GREEN HNBR (HSN) 70 ORINGS

Part number HS70430 is an AS568-430 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 5.1 in (129.54 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.65 in (143.51 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, HNBR (Hydrogenated Nitrile) is valued for the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. The compound resists heat and oxidation, modern refrigerants, and ozone and weathering. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C).

It sees regular use in commercial refrigeration, automotive air conditioning, and heavy-duty powertrain.
