The U70144 is an AS568-144 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 2.487 in (63.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.693 in (68.4 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The compound resists petroleum oils, abrasion and wear, and extrusion under high pressure. Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It is not the right choice where hot water and steam or ketones are present.
Typical settings include off-highway equipment, high-pressure fluid power, and hydraulic cylinders.
U70144 ships individually. Nominal inside diameter is listed as 2 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
