568-223 BLACK HNBR HSN70 O-Ring

Part number HSN70223 is an AS568-223 black HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.609 in (40.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.887 in (47.93 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, strong resistance to rapid gas decompression. This material stands up to ozone and weathering, heat and oxidation, and sour gas and amine inhibitors. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving ketones or strong oxidizing acids call for a different compound.

Typical settings include automotive air conditioning, heavy-duty powertrain, and commercial refrigeration.

Stocked as HSN70223 and sold individually. Unit weight is approximately 1.615 g and nominal inside diameter is listed as 1 5/8 inch.
