*568-237 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90237, this is an AS568-237 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 3.359 in (85.32 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.637 in (92.38 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to petroleum oils, ozone, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where acids and bases or prolonged humidity at elevated temperature are present.

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