APG stocks the U90474, an AS568-474 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 24.94 in (633.48 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 25.49 in (647.45 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Polyurethane (AU/EU) delivers exceptional abrasion resistance and long wear life in dynamic reciprocating service. The compound resists petroleum oils, extrusion under high pressure, and abrasion and wear. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It is not the right choice where hot water and steam or ketones are present.
Maintenance and OEM teams specify it across mining and heavy equipment, off-highway equipment, and press and forming equipment.
Order part number U90474, sold individually. Nominal inside diameter is listed as 25 inch. 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.
