**568-246 URETHANE 90 ORINGS -PR GRADE

APG stocks the U90246, an AS568-246 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 4.484 in (113.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.762 in (120.95 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. It resists impact and shock loading, extrusion under high pressure, and ozone. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with ketones or hot water and steam.

It sees regular use in press and forming equipment, high-pressure fluid power, and mining and heavy equipment.
