**568-248 URETHANE 90 ORINGS -PR. GRADE

Ordered as U90248, this is an AS568-248 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 4.734 in (120.24 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.012 in (127.3 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) is widely chosen for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. This material stands up to extrusion under high pressure, impact and shock loading, and petroleum oils. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.

Common environments for this compound include hydraulic cylinders, construction machinery, and mining and heavy equipment.
