Wiper ring for Terex HC230

The wiper ring, part number 0782 303 07, serves as a protective barrier for the hydraulic cylinders on the Terex HC230 crane. It is installed at the cylinder head to scrape and clean dirt, dust, moisture, and other debris from the surface of the cylinder rod as it retracts into the cylinder body. By preventing these abrasive particles from entering the assembly, the component shields the internal seals and the cylinder bore from damage, which helps to maintain system integrity and prevent fluid leaks.

This component is specifically compatible with the Terex HC230 model. It functions as the primary line of defense for the cylinder sealing system, ensuring that the rod surface remains clean during operation. In heavy machinery, wiper rings are critical for maintaining the cleanliness of the hydraulic fluid and the longevity of the cylinder's internal components, as they prevent the ingress of external contaminants that could otherwise score the rod or degrade the seal performance over time.
