568-469 URETHANE 70 DURO ORINGS

Part number U70469 is an AS568-469 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 19.955 in (506.86 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.505 in (520.83 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. Expect good resistance to abrasion and wear, impact and shock loading, and petroleum oils. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to hot water and steam or acids and bases will shorten service life.

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

This item is sold individually under part number U70469. Nominal inside diameter is listed as 20 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
