Part number U90414 is an AS568-414 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 3.1 in (78.74 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.65 in (92.71 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against extrusion under high pressure, ozone, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers exceptional abrasion resistance and long wear life in dynamic reciprocating service. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).
You will find this material specified across hydraulic cylinders, construction machinery, and off-highway equipment.
Stocked as U90414 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
