The wiper seal is the first and most important line of defense for the precision spool in a hydraulic valve block. Its job is to "scrape" dirt, dust, and water from the spool's surface before it retracts into the housing. If you notice an oil leak from around the valve spool, or if the old wiper is cracked, hardened, or missing, these are classic signs of wear. A faulty wiper allows contaminants to enter the valve, leading to scoring of the spool and housing, which causes internal leaks and a costly failure of the entire valve block.

Wiper seals are single-use parts. Always replace them whenever you replace the internal seals of a valve section.
Working on a hydraulic valve block requires sterile conditions. Ensure that no external contaminants enter the system.
Do not use sharp tools, such as screwdrivers, to install the wiper seal. This can damage its wiping lip.
After any intervention in the hydraulic system, you must replace the filter (we recommend the REDX brand) and refill the system with fresh, clean oil (e.g., HYPTRON).
Answer: Temporarily, yes. A leak indicates that the internal pressure seals have failed. The wiper is a dust seal, not a pressure seal. You should replace the complete seal kit for that section.
Question: Can I reuse the old wiper seal?Answer: It is highly not recommended. The wiper seal is almost always deformed or damaged during removal. Reusing it will not provide protection against dirt.
Question: Why is this small component so important?Answer: It is the cheapest component of the valve block that protects its much more expensive, precision parts - the spool and the housing. Regular replacement of wiper seals is the easiest way to extend the life of the entire valve block.
