APG stocks the U90469, an AS568-469 clear Polyurethane (AU/EU) 90 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.
It resists ozone, 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 toughness that outperforms conventional rubber compounds. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It is not the right choice where prolonged humidity at elevated temperature or hot water and steam are present.
You will find this material specified across press and forming equipment, high-pressure fluid power, and construction machinery.
Stocked as U90469 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
