O-Ring for Demag AC-395

The 997635 O-Ring serves as a critical sealing element within the hydraulic systems of heavy machinery. It is designed to be compressed between two mating surfaces, creating a tight seal that prevents the leakage of hydraulic fluids, lubricants, or other pressurized media. By filling the gap between components, this seal maintains the necessary internal pressure and prevents external contamination from entering the system. Proper installation is necessary to ensure the integrity of hydraulic circuits and to prevent fluid loss during operation.

This component is compatible with Demag AC-395 and AC-395 Serie-76011 U150 models. It is commonly utilized in various hydraulic assemblies, including cylinders, pumps, valves, and pipe connections where a secure seal is required to maintain system performance. As a standard sealing solution, it helps preserve the operational efficiency of the crane by preventing leaks that could otherwise lead to pressure drops or system failure.

O-rings function by deforming under pressure to block fluid paths in both static and dynamic applications. They are used throughout heavy equipment to isolate fluids in different compartments, ensuring that hydraulic power is transmitted effectively through the machine's various actuators and control valves.
