Failure Symptoms

The first sign of failure is often a visible hydraulic fluid leak around the component. If left unaddressed, the leak will worsen, leading to a gradual loss of hydraulic system pressure and performance. Continued operation with a failing seal risks significant contamination of the hydraulic fluid, potentially damaging other system components.

Installation Tip

Ensure the sealing surfaces are perfectly clean and free of debris before attempting installation. Avoid using excessive force or sharp tools, which can easily damage the new seal during insertion.

Service Note

Inspect the hydraulic cylinder rod or piston surface for scoring or wear that could compromise the new seal's integrity.
