Failure Symptoms

Early signs of a failing fitting include minor weeping or spotting of hydraulic fluid around the connection. If left unaddressed, the leak will likely worsen, leading to a significant loss of hydraulic pressure and fluid. Continued operation risks system malfunction and potential damage to hydraulic components due to low fluid levels.

Installation Tip

Clean the threads on both the fitting and the mating port thoroughly before assembly to ensure a proper seal. Do not use excessive force when tightening, as this can damage the threads or the fitting itself.

Service Note

Check the condition of the O-ring or sealing washer, if applicable, and replace it if any signs of degradation are present.
