Cutting ring for Demag AC80-1

The cutting ring, identified by part number 371 243 99, serves as a compression component within the fluid conveyance systems of the Demag AC80-1 crane. This element is integrated into non-welded pipe connections to maintain the integrity of hydraulic and pneumatic lines. When the connector nut is tightened, the ring deforms to grip the exterior surface of the rigid tubing, establishing a mechanical seal that withstands system pressures. Proper installation of this component is necessary to prevent fluid leakage and maintain consistent pressure throughout the crane's circuits.

This component is designed specifically for the Demag AC80-1 model. It functions by creating a metal-to-metal seal between the tube and the fitting body, which is a standard method for securing high-pressure lines in heavy machinery. By biting into the tube wall, the ring secures the connection against vibration and pressure fluctuations, ensuring that the hydraulic or pneumatic system operates within its intended parameters without loss of fluid or pressure.
