Threaded plug for Demag AC80-1

The threaded plug, part number 270 996 40, functions as a sealing component for hydraulic and mechanical systems within heavy machinery. Its primary purpose is to provide a secure closure for threaded ports found in valve blocks, fluid reservoirs, and various equipment housings. By sealing these openings, the plug prevents the loss of internal fluids such as hydraulic oil or coolant while simultaneously protecting the internal circuits from the ingress of external contaminants.

This component is specifically intended for fitment on the Demag AC80-1 crane. Proper installation requires adherence to specified torque settings to ensure the threaded interface maintains a secure seal under operational conditions. Maintaining the integrity of these ports is necessary to prevent fluid leakage and to preserve the overall cleanliness of the machine's internal systems.

Threaded plugs are common in heavy equipment to blank off unused ports or provide access points for maintenance and testing. They are engineered to interface with specific thread standards to ensure a tight fit within the machine's fluid distribution network, supporting the maintenance of correct system pressure and fluid containment.
