Body union for Demag AC80-1

The body union 551 402 40 serves as a connection point within the fluid systems of the Demag AC80-1 all-terrain crane. This component allows for the secure and sealed joining of two sections of tubing or hose, enabling the continuous flow of hydraulic oil, fuel, or coolant throughout the machine. Its design permits disconnection for maintenance or component replacement without requiring the rotation of the entire line, which assists in servicing the crane's complex fluid circuits.

This union is engineered to maintain the integrity of systems operating under varying pressures and temperatures. By ensuring a precise fit, it helps prevent leaks that could lead to pressure loss or system contamination. This part is specifically intended for use with the Demag AC80-1 model.

In heavy machinery, unions function as critical interface points in hydraulic and pneumatic networks. They provide the necessary transition between rigid piping and flexible hoses, allowing for the transmission of pressurized fluids between stationary and moving components. Proper selection of these connectors is necessary to maintain the operational pressure and safety standards of the crane's various hydraulic and fuel subsystems.
