O-ring for Demag AC-395

This O-ring, part number 972003, functions as a sealing element within the hydraulic systems of heavy machinery. It creates a tight seal between two mating surfaces to prevent the escape of hydraulic fluids and to block the entry of external contaminants into the system. By maintaining a secure seal, this component helps preserve the internal pressure and cleanliness required for the hydraulic circuits to operate effectively.

This part is compatible with the Demag AC-395, AC-395 Serie-76011 U150, and AC395 crane models. It is designed to meet the specific fitment requirements for these machines to ensure the integrity of the hydraulic and associated subsystems during operation.

In hydraulic systems, O-rings are used to provide a barrier against fluid migration across joints and connections. As the system is pressurized, the toroidal shape of the seal is compressed, which enhances the sealing force against the surrounding surfaces. This mechanism is essential for preventing pressure drops that could otherwise impair the lifting or movement capabilities of the crane. Regular inspection and maintenance of these seals are standard procedures to ensure the continued efficiency of the hydraulic circuit.
