568-107 HSN90 DURO ORINGS

Part number HSN90107 is an AS568-107 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring with an inside diameter of 0.206 in (5.23 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.412 in (10.46 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

HNBR (Hydrogenated Nitrile) is widely chosen for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. The material holds up against heat and oxidation, sour gas and amine inhibitors, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or ketones will shorten service life.

Maintenance and OEM teams specify it across automotive air conditioning, oilfield and downhole equipment, and commercial refrigeration.

HSN90107 ships individually. Nominal inside diameter is listed as 7/32 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
