Quad ring for Demag HC1020

The quad ring 32347140 serves as a sealing component within the hydraulic and pneumatic systems of the Demag HC1020 crane. Featuring a four-lobed profile, this seal creates a contact surface that helps maintain a tight barrier against fluid or gas escape. It is intended for installation in hydraulic assemblies where maintaining pressure is necessary for the proper operation of the crane's various functions.

This component is compatible with the Demag HC1020 model. It is designed to fit into specific grooves within hydraulic cylinders, valves, or pump connections to ensure a secure seal. By maintaining its shape under pressure, the quad ring helps prevent internal or external leaks that can affect the performance of the hydraulic circuit.

Quad rings are used in heavy machinery to provide a stable seal in dynamic or static applications. Their four-lobed geometry is engineered to resist twisting or rolling within the housing, which helps maintain consistent sealing contact during the operation of hydraulic components. Proper installation of this seal is necessary to support the integrity of the hydraulic system and prevent the loss of pressurized fluid.
