568-252 URETHANE 90 ORINGS -PREM GRADE

U90252 is an AS568-252 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 5.234 in (132.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.512 in (140 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against impact and shock loading, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure, very high tensile strength and load capacity. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

Maintenance and OEM teams specify it across off-highway equipment, high-pressure fluid power, and mining and heavy equipment.

U90252 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
