O-ring for Demag AC80-1

This O-ring serves as a sealing component within the hydraulic systems of the Demag AC80-1 all-terrain crane. It is designed to be seated within a machined groove and compressed during assembly to form a barrier against fluid loss. By maintaining this seal, the component prevents the leakage of hydraulic oil and lubricants while simultaneously blocking the entry of dust, water, and other debris into sensitive internal areas of the machinery.

The component is compatible with the Demag AC80-1 model. It is designed to function within the specific pressure and temperature parameters of the crane's hydraulic circuits, transmission, and engine assemblies. It is identified by part number 997 635 00.

In heavy machinery, O-rings are used to maintain system pressure and protect internal mechanical parts from premature wear. They are typically installed at connection points, cylinder interfaces, and valve blocks to ensure the hydraulic circuit remains closed and pressurized during operation. Regular inspection and replacement of these seals during maintenance cycles are standard procedures for managing fluid systems in mobile cranes.
