568-126 HSN90 DURO ORINGS

Part number HSN90126 is an AS568-126 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. The material holds up against heat and oxidation, modern refrigerants, and petroleum oils and fuels. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Applications involving strong oxidizing acids or ketones call for a different compound.

You will find this material specified across commercial refrigeration, oilfield and downhole equipment, and automotive air conditioning.

Reference part number HSN90126 when ordering; the item is sold individually. Unit weight is approximately 0.8415 g. Check the compound against your process media, pressure and temperature before committing to a design.
