The O-ring 12420 serves as a sealing element within the hydraulic and pneumatic circuits of the Demag AC395 crane. It functions by creating a seal between two mating surfaces to prevent the leakage of pressurized fluids or gases. By maintaining this seal, the component helps preserve the pressure levels required for the proper operation of the machine systems.
This part is specifically compatible with the Demag AC395 mobile crane model. It is designed for use in various applications throughout the machine, including hydraulic cylinders, control valves, pipe connections, and pumps where a fluid-tight seal is required to maintain system integrity.
O-rings are used in heavy machinery to provide a barrier against fluid loss and contamination. When installed in hydraulic or pneumatic assemblies, they compensate for minor surface irregularities to ensure that fluid remains contained within the circuit, which is necessary for the consistent performance of the equipment.
