Seal kit for Demag H170

The 98841000 seal kit consists of a collection of seals, O-rings, wipers, and backup rings designed to maintain the operating pressure and prevent fluid leakage within hydraulic cylinders, valves, or pumps. By replacing these components, the hydraulic system regains its ability to hold pressure effectively, which is necessary for the consistent operation of the machine's hydraulic circuits.

This kit is specifically configured for the Demag H170 hydraulic excavator. It is designed to meet the dimensional tolerances required for the specific housings found in this model's hydraulic assemblies. The components within the kit are selected to ensure compatibility with standard hydraulic fluids, operating temperatures, and pressure ranges encountered during heavy-duty excavation and earthmoving tasks.

In any hydraulic system, seals serve to isolate fluid chambers and prevent external leaks. Piston seals manage the pressure differential across the piston, while rod seals prevent fluid from escaping along the cylinder rod. Wipers are included to clear debris from the rod surface before it enters the cylinder, protecting internal surfaces from contamination. Maintaining these seals is a standard procedure to ensure the hydraulic system continues to deliver the required force and speed for machine functions.
