568-141 URETHANE 70 DURO ORINGS

Ordered as U70141, this is an AS568-141 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 2.3 in (58.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.506 in (63.65 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists ozone, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C).

Common environments for this compound include construction machinery, mining and heavy equipment, and high-pressure fluid power.

U70141 ships individually. Nominal inside diameter is listed as 2 5/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
