568-355 URETHANE 90 ORINGS -PREM GRADE

Part number U90355 is an AS568-355 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 5.225 in (132.72 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.645 in (143.38 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. The material holds up against extrusion under high pressure, impact and shock loading, and ozone. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C).

Common environments for this compound include construction machinery, high-pressure fluid power, and off-highway equipment.

This item is sold individually under part number U90355. Nominal inside diameter is listed as 5 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
