568-275 URETHANE 90 ORINGS -PREM GRADE

U90275 is an AS568-275 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) is specified here for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. It resists abrasion and wear, impact and shock loading, and extrusion under high pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).

It sees regular use in mining and heavy equipment, hydraulic cylinders, and off-highway equipment.
