Seal kit for Demag AC 615

The seal kit 77816873 provides the necessary components to restore the sealing integrity of hydraulic systems within heavy machinery. It is used to service hydraulic cylinders, valves, pumps, and other actuators by replacing worn seals to prevent fluid leakage and the ingress of external contaminants. By maintaining the integrity of these interfaces, the kit helps preserve system pressure and ensures the precise operation of hydraulic functions.

This component is specifically compatible with the Demag AC 615 all-terrain crane. It is suitable for maintenance tasks involving the boom cylinders, outriggers, and steering systems of this crane model. The kit typically includes a selection of lip seals, o-rings, backup rings, piston seals, and rod seals designed to match the specific dimensions and operational requirements of the hydraulic assemblies found on this equipment.

Seal kits are used in hydraulic systems to create a barrier between moving parts and stationary housings. They manage the internal pressure of the circuit and prevent the loss of hydraulic fluid, which is necessary for the consistent movement of crane components. Regular replacement of these seals during maintenance cycles helps prevent pressure loss and potential damage to the internal surfaces of hydraulic cylinders and valves.
