Plug for Demag AC80-1

The 490 054 40 plug is a sealing component used in the Demag AC80-1 crane. This part is designed to seal specific orifices, ports, or openings found in various housings, reservoirs, or fluid systems within the machine. By providing a secure closure, it prevents the escape of hydraulic oil or other fluids and protects internal components from the ingress of external contaminants.

This component is compatible with the Demag AC80-1 crane model. It is engineered to fit the specified ports to maintain the integrity of the machine's fluid circuits. Proper installation of this plug ensures that the system remains closed and pressurized according to the crane's operational requirements.

In heavy machinery, plugs of this type are used to seal unused ports or access points in hydraulic and pneumatic systems. They are essential for maintaining the containment of pressurized fluids, which is necessary for the correct operation of actuators and other system components. By ensuring these access points are sealed, the plug helps maintain system pressure and prevents environmental contamination from leaking fluids.
