568-250 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90250, this is an AS568-250 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 4.984 in (126.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.262 in (133.65 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) offers very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. The material holds up against petroleum oils, impact and shock loading, and extrusion under high pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Applications involving acids and bases or prolonged humidity at elevated temperature call for a different compound.

You will find this material specified across mining and heavy equipment, off-highway equipment, and construction machinery.

Order part number U90250, sold individually. Nominal inside diameter is listed as 5 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
