568-471 GREEN HNBR (HSN) 70 ORINGS

The HS70471 is an AS568-471 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 21.955 in (557.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 22.505 in (571.63 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

HNBR (Hydrogenated Nitrile) is specified here for strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. This material stands up to heat and oxidation, petroleum oils and fuels, and sour gas and amine inhibitors. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

It sees regular use in commercial refrigeration, engine timing systems, and automotive air conditioning.

HS70471 ships individually. Nominal inside diameter is listed as 22 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
