568-039 URETHANE 90 ORINGS -PREM GRADE

Part number U90039 is an AS568-039 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 2.739 in (69.57 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.879 in (73.13 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, very high tensile strength and load capacity. The material holds up against petroleum oils, abrasion and wear, and ozone. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C).

Maintenance and OEM teams specify it across off-highway equipment, press and forming equipment, and high-pressure fluid power.

This item is sold individually under part number U90039. 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.
