Failure Symptoms

Visible hydraulic fluid leaks around the sealed component are the first sign of a failing 331-7388 seal. If ignored, these leaks can lead to a significant loss of hydraulic fluid and system pressure. Continued operation with a compromised seal risks internal component damage due to insufficient lubrication and contamination.

Installation Tip

Ensure the mating surfaces are meticulously clean and free of any debris before installing the new 331-7388 seal. Avoid using sharp tools that could scratch or nick the seal during insertion, as this will compromise its sealing capability.

Service Note

Inspect the surrounding hydraulic lines and fittings for any signs of wear or damage when replacing the 331-7388 seal.
