568-469 GREEN HNBR (HSN) 70 ORINGS

HS70469 is an AS568-469 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 19.955 in (506.86 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.505 in (520.83 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists sour gas and amine inhibitors, heat and oxidation, and modern refrigerants. HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, the oil resistance of nitrile with substantially better heat capability. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where esters or ketones are present.

Common environments for this compound include heavy-duty powertrain, commercial refrigeration, and engine timing systems.

Stocked as HS70469 and sold individually. Nominal inside diameter is listed as 20 inch. Check the compound against your process media, pressure and temperature before committing to a design.
