Part number U90206 is an AS568-206 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 0.484 in (12.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.762 in (19.35 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. The material holds up against extrusion under high pressure, impact and shock loading, and petroleum oils. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.
Maintenance and OEM teams specify it across construction machinery, high-pressure fluid power, and mining and heavy equipment.
Reference part number U90206 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
