The U90040 is an AS568-040 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 2.864 in (72.75 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.004 in (76.3 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.
Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. The compound resists impact and shock loading, ozone, and abrasion and wear. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to acids and bases or prolonged humidity at elevated temperature will shorten service life.
Maintenance and OEM teams specify it across press and forming equipment, mining and heavy equipment, and hydraulic cylinders.
Order part number U90040, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
