Seal kit for Demag H170

The 98928300 seal kit consists of a collection of gaskets, O-rings, piston seals, rod seals, wipers, and guide rings. These components function to maintain the internal pressure of hydraulic systems by preventing the leakage of oil or air while simultaneously blocking the ingress of dust, water, and other external contaminants. By ensuring the system remains sealed, this kit helps maintain the operating efficiency of hydraulic actuators and protects internal surfaces from environmental exposure.

This kit is specifically configured for the Demag H170 hydraulic excavator, including units with serial number 82103. It is intended for use during the maintenance and overhaul of hydraulic cylinders, pumps, motors, and valves found within the machine. These components are designed to meet the specific dimensional requirements of the H170 hydraulic system to ensure a proper fit during installation.

Seal kits are used in hydraulic machinery to restore the sealing interface between moving parts. In heavy equipment, these kits are employed to address pressure loss or fluid bypass, which can occur as seals naturally degrade over time due to operational cycles and exposure to hydraulic fluids.
