568-453 URETHANE 70 DURO ORINGS

Ordered as U70453, this is an AS568-453 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 11.975 in (304.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.525 in (318.14 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, exceptional abrasion resistance. This material stands up to ozone, abrasion and wear, and impact and shock loading. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or acids and bases will shorten service life.

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

U70453 ships individually. Nominal inside diameter is listed as 12 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
