Seal kit for Demag AC 615

The 77816473 seal kit provides a complete set of seals, O-rings, and related sealing elements required for the maintenance and repair of hydraulic components. These parts are used to restore the internal and external sealing of hydraulic cylinders, valves, pumps, and motors, ensuring that the system maintains its required operating pressure and prevents fluid loss or the ingress of external contaminants.

This kit is compatible with the Demag AC 615 all-terrain crane. It is intended for use in the various hydraulic circuits that control critical crane functions, including boom elevation, outrigger extension, and superstructure rotation. By providing the specific components needed to reseal these assemblies, the kit assists in maintaining the operational integrity of the crane's hydraulic systems.

In hydraulic systems, seals act as the primary barrier between moving parts and pressurized fluid. They are engineered to fit into specific grooves to prevent leaks that can lead to pressure drops, erratic component movement, or reduced load capacity. Regular replacement of these sealing elements during scheduled maintenance helps manage the internal and external fluid containment of the machine's hydraulic circuits.
