568-033 URETHANE 90 ORINGS -PREM GRADE

Part number U90033 is an AS568-033 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 1.989 in (50.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.129 in (54.08 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) is known for very high tensile strength and load capacity, exceptional abrasion resistance. It resists petroleum oils, extrusion under high pressure, and ozone. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Applications involving acids and bases or ketones call for a different compound.

You will find this material specified across construction machinery, mining and heavy equipment, and hydraulic cylinders.
