Failure Symptoms

The most immediate sign of a failing hydraulic fitting is the appearance of hydraulic fluid leaks at the connection point. If left unaddressed, these leaks can lead to a significant loss of hydraulic fluid and system pressure, causing equipment functions to become sluggish or inoperative. Continued operation with leaking fittings risks contamination of the hydraulic system and potential damage to the pump or other components.

Installation Tip

Ensure both the fitting threads and the receiving port are clean and free of debris before attempting to connect the hose. Do not reuse old O-rings or seals; always use new ones appropriate for the fitting and system pressure.

Service Note

Inspect the hydraulic hose for wear or damage, and check the adjacent hydraulic component's port for thread damage when replacing a hydraulic fitting.
