O-ring for Demag AC80-1

The O-ring, part number 972 003 00, is a sealing component used within the Demag AC80-1 crane. It functions as a static or dynamic seal to prevent the leakage of hydraulic oils, lubricants, or coolants while simultaneously blocking the entry of external contaminants such as dust and moisture into critical machine systems. By maintaining a proper seal, this component ensures that hydraulic and lubrication circuits remain pressurized and free from fluid loss.

This part is compatible with the Demag AC80-1 crane. It is commonly utilized in various applications across the machine, including hydraulic hose connections, cylinders, valves, pumps, and engine or transmission housings. Proper sealing is essential for the integrity of these systems, as it prevents pressure drops and fluid contamination that can affect operational efficiency.

O-rings act as the primary barrier in fluid power systems, providing a seal between two mating surfaces. They are compressed during installation to fill the gap between components, effectively containing pressurized fluids and preventing environmental debris from entering sensitive mechanical assemblies.
