568-149 HSN90 DURO ORINGS

HSN90149 is an AS568-149 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 2.8 in (71.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.006 in (76.35 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists modern refrigerants, sour gas and amine inhibitors, and heat and oxidation. HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with strong oxidizing acids or ketones.

It sees regular use in commercial refrigeration, oilfield and downhole equipment, and automotive air conditioning.

HSN90149 ships individually. Unit weight is approximately 1.6734 g and nominal inside diameter is listed as 2 13/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
