The back-up ring, part number 0752 668 12, serves as a support component for dynamic seals in the hydraulic and pneumatic circuits of the Terex HC230 crane. By providing a rigid barrier, it prevents O-rings from being forced out of their grooves or deforming under high pressure conditions, which helps maintain the integrity of the sealing system. This component is installed alongside the O-ring to ensure the seal remains properly seated during operation.
This part is specifically compatible with the Terex HC230 model. It is used in various hydraulic assemblies, including cylinders and valves, to protect the primary sealing elements from pressure-induced failure. By maintaining the correct shape and position of the O-ring, this component helps prevent fluid leakage and supports the overall functional efficiency of the machine's hydraulic systems.
