568-033 HSN90 DURO ORINGS

The HSN90033 is an AS568-033 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 1.989 in (50.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.129 in (54.08 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against modern refrigerants, sour gas and amine inhibitors, and heat and oxidation. HNBR (Hydrogenated Nitrile) is widely chosen for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or strong oxidizing acids.

Common environments for this compound include automotive air conditioning, oilfield and downhole equipment, and engine timing systems.

Order part number HSN90033, sold individually. Unit weight is approximately 0.5546 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
