*568-029 URETHANE 90 ORINGS -PREM GRADE

U90029 is an AS568-029 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 1.489 in (37.82 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.629 in (41.38 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. This material stands up to extrusion under high pressure, impact and shock loading, and ozone. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where hot water and steam or ketones are present.

Maintenance and OEM teams specify it across construction machinery, high-pressure fluid power, and mining and heavy equipment.

This item is sold individually under part number U90029. Nominal inside diameter is listed as 1 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
