568-254 URETHANE 90 ORINGS -PREM GRADE

Part number U90254 is an AS568-254 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 5.484 in (139.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.762 in (146.35 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Polyurethane (AU/EU) delivers very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The compound resists ozone, impact and shock loading, and extrusion under high pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.

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

Order part number U90254, sold individually. Nominal inside diameter is listed as 5 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
