Part number U90209 is an AS568-209 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 0.671 in (17.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.949 in (24.1 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. It resists extrusion under high pressure, ozone, and petroleum oils. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.
Common environments for this compound include press and forming equipment, off-highway equipment, and mining and heavy equipment.
This item is sold individually under part number U90209. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
