568-393 URETHANE 90 ORINGS -PREM GRADE

The U90393 is an AS568-393 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 24.36 in (618.74 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. The material holds up against extrusion under high pressure, impact and shock loading, and petroleum oils. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

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

This item is sold individually under part number U90393. Nominal inside diameter is listed as 24 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
