Product Specification

-
Part number U70378 is an AS568-378 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 10.475 in (266.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.895 in (276.73 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) is valued for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. This material stands up to ozone, petroleum oils, and impact and shock loading. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It should not be specified for service in hot water and steam or acids and bases.

You will find this material specified across construction machinery, mining and heavy equipment, and hydraulic cylinders.

Stocked as U70378 and sold individually. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
