568-013 URETHANE 70 DURO ORINGS

This o-ring is supplied in AS568-013 clear Polyurethane (AU/EU) 70 Shore A with an inside diameter of 0.426 in (10.82 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.566 in (14.38 mm), catalogued under part number U70013. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Applications involving acids and bases or prolonged humidity at elevated temperature call for a different compound.

It sees regular use in press and forming equipment, high-pressure fluid power, and construction machinery.

This item is sold individually under part number U70013. Nominal inside diameter is listed as 7/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
