*568-239 URETHANE 90 ORINGS

The U90239 is an AS568-239 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 3.609 in (91.67 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.887 in (98.73 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against ozone, impact and shock loading, and extrusion under high pressure. Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or acids and bases call for a different compound.

You will find this material specified across off-highway equipment, hydraulic cylinders, and press and forming equipment.
