568-381 URETHANE 70 DURO ORINGS

U70381 is an AS568-381 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 11.975 in (304.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 12.395 in (314.83 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The compound resists abrasion and wear, extrusion under high pressure, and ozone. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Exposure to hot water and steam or acids and bases will shorten service life.

Common environments for this compound include hydraulic cylinders, off-highway equipment, and press and forming equipment.

Stocked as U70381 and sold individually. Nominal inside diameter is listed as 12 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.
