568-384 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-384 clear Polyurethane (AU/EU) 90 Shore A built to an inside diameter of 14.975 in (380.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 15.395 in (391.03 mm), catalogued under part number U90384. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to impact and shock loading, ozone, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Exposure to ketones or prolonged humidity at elevated temperature will shorten service life.

You will find this material specified across construction machinery, hydraulic cylinders, and press and forming equipment.

U90384 ships individually. Nominal inside diameter is listed as 15 inch. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
