*568-112 URETHANE 90 ORINGS -PREM GRADE

The U90112 is an AS568-112 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 0.487 in (12.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.693 in (17.6 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. The material holds up against ozone, extrusion under high pressure, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

Maintenance and OEM teams specify it across high-pressure fluid power, off-highway equipment, and hydraulic cylinders.
