Back-up ring for Terex HC230

This back-up ring, part number 0782 410 15, serves as an auxiliary sealing component within the hydraulic systems of the Terex HC230 crane. It is engineered to work in conjunction with primary dynamic seals, such as O-rings, to prevent seal extrusion when the system is subjected to high operating pressures. By providing a rigid support surface, this component ensures that the primary seal retains its shape and functional effectiveness, which is necessary for maintaining hydraulic performance in heavy-duty lifting equipment.

This component is specifically compatible with the Terex HC230 model. It is designed to be installed alongside primary seals to prevent both internal and external fluid leakage, which can otherwise lead to a loss of system efficiency or operational failure. The back-up ring is intended for use in hydraulic assemblies where maintaining seal geometry under pressure is required for the safe and consistent operation of the crane's hydraulic circuits.
