568-382 URETHANE 90 ORINGS -PREM GRADE

U90382 is an AS568-382 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 12.975 in (329.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 13.395 in (340.23 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists impact and shock loading, ozone, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for 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).

You will find this material specified across mining and heavy equipment, hydraulic cylinders, and high-pressure fluid power.

This item is sold individually under part number U90382. Nominal inside diameter is listed as 13 inch. Review your operating media and conditions against this specification before installation.
