Wiper ring for Terex HC230

The wiper ring, identified by part number 0782 381 07, is a component installed at the end of hydraulic cylinders where the rod enters and exits the cylinder body. Its primary function is to scrape and clean the surface of the rod as it extends and retracts, preventing dirt, dust, moisture, and debris from entering the internal sealing system of the cylinder. By keeping the rod surface clean, this component protects the primary seals and the hydraulic fluid from contamination.

This part is compatible with the Terex HC230 crane. Proper maintenance of the wiper ring helps prevent damage to the rod surface and internal seals, which can otherwise lead to fluid leaks and loss of system pressure. By excluding external contaminants, the wiper ring supports the overall integrity of the hydraulic cylinder assembly during operation.

Wiper rings serve as the first line of defense in hydraulic and pneumatic cylinder assemblies. They are positioned to clear debris from the rod before it reaches the main rod seal, ensuring that the internal environment of the cylinder remains clean and free from abrasive particles that could compromise the sealing performance over time.
