Failure Symptoms

A leaking air hose will first manifest as a noticeable hissing sound or a drop in system pressure. If ignored, the leak will worsen, leading to sluggish or unresponsive operation of the equipment it serves. Continued use with a compromised hose can result in system component damage due to insufficient pressure or contamination ingress.

Installation Tip

Ensure all connection points are clean and free of debris before attaching the new hose to prevent leaks. Do not twist or kink the hose during installation, as this can restrict flow and cause premature failure.

Service Note

Inspect all adjacent hoses, fittings, and clamps for wear or damage when replacing the CAT 131-6682 air hose.
