Part number U90026 is an AS568-026 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 1.239 in (31.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.379 in (35.03 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Polyurethane (AU/EU) is known for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. It resists extrusion under high pressure, ozone, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where ketones or hot water and steam are present.
Common environments for this compound include high-pressure fluid power, press and forming equipment, and mining and heavy equipment.
Stocked as U90026 and sold individually. Nominal inside diameter is listed as 1 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
