U90144 is an AS568-144 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 2.487 in (63.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.693 in (68.4 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. Expect good resistance to impact and shock loading, abrasion and wear, and extrusion under high pressure. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It is not the right choice where prolonged humidity at elevated temperature or ketones are present.

Typical settings include construction machinery, high-pressure fluid power, and off-highway equipment.
