568-464 GREEN HNBR (HSN) 70 ORINGS

This o-ring is supplied in AS568-464 green HNBR (Hydrogenated Nitrile) 70 Shore A with an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm), catalogued under part number HS70464. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) is specified for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. The compound resists heat and oxidation, petroleum oils and fuels, and ozone and weathering. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where esters or ketones are present.

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

HS70464 ships individually. Nominal inside diameter is listed as 17 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
