*568-124 URETHANE 90 ORINGS

This o-ring is supplied in AS568-124 clear Polyurethane (AU/EU) 90 Shore A with an inside diameter of 1.237 in (31.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.443 in (36.65 mm), catalogued under part number U90124. It creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against abrasion and wear, impact and shock loading, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. 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 acids and bases.

You will find this material specified across high-pressure fluid power, hydraulic cylinders, and off-highway equipment.

Order part number U90124, sold individually. Nominal inside diameter is listed as 1 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
