568-276 URETHANE 70 DURO ORINGS

The U70276 is an AS568-276 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 10.984 in (278.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.262 in (286.05 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists impact and shock loading, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Exposure to ketones or acids and bases will shorten service life.

You will find this material specified across high-pressure fluid power, hydraulic cylinders, and press and forming equipment.

Stocked as U70276 and sold individually. Nominal inside diameter is listed as 11 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
