568-451 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90451, this is an AS568-451 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 10.975 in (278.77 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.525 in (292.74 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The compound resists impact and shock loading, extrusion under high pressure, and ozone. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

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