This o-ring is supplied in AS568-342 clear Polyurethane (AU/EU) 90 Shore A built to an inside diameter of 3.6 in (91.44 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.02 in (102.11 mm), catalogued under part number U90342. It delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to impact and shock loading, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in prolonged humidity at elevated temperature or ketones.

You will find this material specified across construction machinery, high-pressure fluid power, and hydraulic cylinders.

This item is sold individually under part number U90342. 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.
