568-369 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70369, an AS568-369 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 7.975 in (202.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.395 in (213.23 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to ozone and weathering, sour gas and amine inhibitors, and heat and oxidation. HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to ketones or chlorinated hydrocarbons will shorten service life.

You will find this material specified across engine timing systems, oilfield and downhole equipment, and commercial refrigeration.

Stocked as HS70369 and sold individually. Nominal inside diameter is listed as 8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
