What does a rod wiper do in a hydraulic system?

The function of a rod wiper in a hydraulic system is to prevent contaminants from entering the hydraulic cylinder. This component is crucial for maintaining the integrity of the hydraulic fluid and ensuring the smooth operation of the hydraulic system. By effectively wiping the rod as it extends and retracts, the wiper removes dirt, debris, and moisture that could otherwise compromise the seals within the system or damage its internal components. This preventative measure helps to prolong the life of the hydraulic system and maintains its efficiency.

While sealing the hydraulic fluid, releasing pressure, and monitoring pressure levels are important functions in hydraulic systems, those actions are performed by different components, like seals, pressure relief valves, and pressure gauges. The rod wiper's primary role is specifically related to keeping contaminants out, which underlines its importance in hydraulic maintenance and operation.
