568-135 URETHANE 70 DURO ORINGS

Part number U70135 is an AS568-135 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 1.925 in (48.9 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.131 in (54.13 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to extrusion under high pressure, petroleum oils, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) offers very high tensile strength and load capacity, exceptional abrasion resistance. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or hot water and steam call for a different compound.

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

This item is sold individually under part number U70135. Nominal inside diameter is listed as 1 15/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
