APG stocks the U70313, an AS568-313 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 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 known for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Expect good resistance to abrasion and wear, petroleum oils, and extrusion under high pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or ketones.
Maintenance and OEM teams specify it across construction machinery, off-highway equipment, and hydraulic cylinders.
U70313 ships individually. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
