568-452 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-452 clear Polyurethane (AU/EU) 90 Shore A measuring an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm), catalogued under part number U90452. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists extrusion under high pressure, abrasion and wear, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It is not the right choice where ketones or prolonged humidity at elevated temperature are present.

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

Order part number U90452, sold individually. Nominal inside diameter is listed as 11 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
