568-376 URETHANE 90 ORINGS -PREM GRADE

U90376 is an AS568-376 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 9.725 in (247.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.145 in (257.68 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against petroleum oils, impact and shock loading, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It should not be specified for service in ketones or acids and bases.

Maintenance and OEM teams specify it across off-highway equipment, hydraulic cylinders, and construction machinery.
