Threaded plug for Demag AC80-1

This threaded plug, identified by part number 173 448 40, serves as a closure for various openings within the Demag AC80-1 all-terrain crane. It is engineered to seal cavities in hydraulic systems, pneumatic lines, gearboxes, or fluid reservoirs to prevent the escape of internal fluids and the ingress of external contaminants like dust and moisture.

The component is specifically compatible with the Demag AC80-1 model. Proper installation of this threaded plug ensures that the machine's internal systems remain isolated from the environment, preventing pressure loss and protecting sensitive components from debris that could otherwise lead to premature wear or system failure.

In heavy machinery, threaded plugs are used to close off service ports, drain points, or inspection holes in pressurized or fluid-filled assemblies. By providing a secure, removable seal, these components allow for maintenance access while ensuring that the system remains airtight or leak-proof during operation. Maintaining the correct seal at these points is necessary for the consistent performance of the crane's hydraulic and lubrication circuits.
