Threaded plug for Demag AC80-1

The threaded plug, part number 412 533 12, is a sealing component used to close threaded openings in fluid systems or mechanical cavities within the machine. Its primary function is to seal an orifice, preventing the leakage of liquids such as oil, hydraulic fluid, or coolant, while also blocking the entry of external contaminants like dirt, dust, or moisture. This component is commonly used to secure inspection ports, drainage points, filling ports, or unused openings in valve blocks, housings, and tanks.

This part is specifically designed for the Demag AC80-1 mobile crane. It features a precise thread to ensure a secure fit and effective sealing within the machine's various systems, including hydraulic circuits, transmissions, and engine assemblies. Proper installation and maintenance of this plug are necessary to maintain system integrity and prevent fluid loss or internal contamination.

In heavy machinery, threaded plugs are used throughout the chassis and powertrain to isolate internal cavities. By maintaining a tight seal, these components help preserve the operating pressure and fluid levels required for the mechanical systems to function correctly.
