O-ring seal for Demag AC80-1

The O-ring seal, part number 346 952 40, is a circular sealing element used in the Demag AC80-1 crane. It functions as a gasket to create a tight interface between two mating surfaces, effectively containing hydraulic fluids or pneumatic gases within the system and preventing external contaminants from entering sensitive areas. By maintaining this seal, the component helps ensure the integrity of connections throughout the crane, including those found in cylinders, valves, pumps, and pipe fittings.

This component is specifically sized for the Demag AC80-1. Proper installation of these seals is necessary to keep the hydraulic system at its required operating pressure, which supports the lifting capacity and control responsiveness of the crane. Regular inspection and timely replacement of these seals are standard procedures in the maintenance of heavy machinery to prevent fluid leaks and pressure drops that can affect operational efficiency.
