Signs your Hydraulic Hose is about to Fail
Hydraulic hose failure can cause equipment damage, safety hazards, and costly downtime. Here’s what to look for before it happens.
Visible Oil Leaks
Even small leaks indicate the hose cover has been breached or the fitting seal is compromised.
Unusual Noises or Vibration
“Chattering” or pressure spikes often accompany an internal restriction or delamination.
Blisters or Bubbles
Air, fluid, or gas trapped under the cover means internal damage — replace immediately.
Fitting Corrosion or Movement
Rust, looseness, or twisted fittings suggest improper assembly or pressure fatigue.
Cracks and Abrasion
Surface cracking or exposed wire reinforcement are early failure signs, especially near bends.
Stiff or Brittle Hose
A hose that’s lost flexibility may have been overheated or chemically damaged.
Never ignore small changes — most hose bursts are preceded by visible warning signs.
