568-374 URETHANE 90 ORINGS -PREM GRADE

U90374 is an AS568-374 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 9.225 in (234.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.645 in (244.98 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) is known for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. The material holds up against impact and shock loading, extrusion under high pressure, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or acids and bases.

Common environments for this compound include press and forming equipment, high-pressure fluid power, and hydraulic cylinders.
