568-264 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-264 clear Polyurethane (AU/EU) 90 Shore A with an inside diameter of 7.484 in (190.09 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.762 in (197.15 mm), catalogued under part number U90264. It compresses into its gland to block fluid or gas migration across a joint.

The material holds up against abrasion and wear, petroleum oils, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in acids and bases or ketones.

Typical settings include mining and heavy equipment, hydraulic cylinders, and press and forming equipment.

Order part number U90264, sold individually. Nominal inside diameter is listed as 7 1/2 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
