568-038 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90038, this is an AS568-038 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 2.614 in (66.4 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.754 in (69.95 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against ozone, petroleum oils, and extrusion under high pressure. Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or prolonged humidity at elevated temperature.

Maintenance and OEM teams specify it across construction machinery, high-pressure fluid power, and press and forming equipment.
