568-166 GREEN HNBR (HSN) 70 ORINGS

Part number HS70166 is an AS568-166 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 6.737 in (171.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.943 in (176.35 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists ozone and weathering, sour gas and amine inhibitors, and heat and oxidation. HNBR (Hydrogenated Nitrile) delivers long service life in refrigerant and oilfield duty, strong resistance to rapid gas decompression. Published continuous service range is -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 oilfield and downhole equipment, heavy-duty powertrain, and commercial refrigeration.
