568-902 URETHANE 90 ORINGS -PREM GRADE

The U90902 is an AS568-902 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 0.239 in (6.07 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.367 in (9.32 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Expect good resistance to petroleum oils, ozone, and impact and shock loading. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to acids and bases or ketones will shorten service life.

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

U90902 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
