*568-225 URETHANE 90 ORINGS -PR GRADE

APG stocks the U90225, an AS568-225 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to abrasion and wear, ozone, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C).

Common environments for this compound include hydraulic cylinders, high-pressure fluid power, and construction machinery.

Reference part number U90225 when ordering; the item is sold individually. Nominal inside diameter is listed as 1 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
