568-413 GREEN HNBR (HSN) 70 ORINGS

Part number HS70413 is an AS568-413 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.975 in (75.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.525 in (89.54 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

HNBR (Hydrogenated Nitrile) is specified here for long service life in refrigerant and oilfield duty, oil resistance of nitrile with substantially better heat capability. Expect good resistance to sour gas and amine inhibitors, ozone and weathering, and heat and oxidation. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Applications involving ketones or strong oxidizing acids call for a different compound.

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

Stocked as HS70413 and sold individually. Nominal inside diameter is listed as 3 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
