Plug for Demag AC80-1

The plug, identified by part number 762 983 73, is used to seal openings in various systems of the Demag AC80-1 crane. It is commonly installed in fluid reservoirs, gear housings, maintenance access points, and inspection ports. By providing a secure closure, this component prevents the leakage of essential fluids such as oil, coolant, or fuel while simultaneously blocking the entry of dust, dirt, and moisture that could compromise internal assemblies.

This component is compatible with the Demag AC80-1 crane model. It is also referred to as a Stopfen Plug in technical documentation. The part is engineered to maintain the integrity of hydraulic, lubrication, and transmission systems by ensuring that all designated ports remain sealed during operation.

Plugs of this type function as protective barriers in heavy machinery. They are used to close off unused ports or provide access to systems for maintenance and fluid level checks. Maintaining these seals is standard practice to ensure that internal components remain protected from environmental debris and that system pressures are preserved.
