568-138 URETHANE 70 DURO ORINGS

Part number U70138 is an AS568-138 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 2.112 in (53.64 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.318 in (58.88 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Polyurethane (AU/EU) is specified here for exceptional abrasion resistance, very high tensile strength and load capacity. The compound resists extrusion under high pressure, ozone, and petroleum oils. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with ketones or prolonged humidity at elevated temperature.

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

U70138 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
