568-003 URETHANE 90 ORINGS -PREM GRADE

The U90003 is an AS568-003 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 0.056 in (1.42 mm), a cross section of 0.06 in (1.52 mm), and an outside diameter of 0.176 in (4.47 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. This material stands up to impact and shock loading, extrusion under high pressure, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or acids and bases.

Maintenance and OEM teams specify it across hydraulic cylinders, high-pressure fluid power, and construction machinery.

U90003 ships individually. Nominal inside diameter is listed as 1/16 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.
