568-402 URETHANE 70 DURO ORINGS

This o-ring is supplied in AS568-402 clear Polyurethane (AU/EU) 70 Shore A supplied with an inside diameter of 1.6 in (40.64 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.15 in (54.61 mm), catalogued under part number U70402. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. The compound resists petroleum oils, impact and shock loading, and extrusion under high pressure. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or acids and bases.

Maintenance and OEM teams specify it across mining and heavy equipment, high-pressure fluid power, and hydraulic cylinders.

U70402 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
