568-373 URETHANE 90 ORINGS -PREM GRADE

U90373 is an AS568-373 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against petroleum oils, impact and shock loading, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) offers very high tensile strength and load capacity, exceptional abrasion resistance. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.

Typical settings include construction machinery, mining and heavy equipment, and high-pressure fluid power.

Stocked as U90373 and sold individually. Nominal inside diameter is listed as 9 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
