Question: 1 / 400

What does it indicate if a hydraulic hose has blisters?

Normal wear

A potential failure

When you observe blisters on a hydraulic hose, it typically signals a potential failure. Blistering is a sign that the integrity of the hose is compromised, often due to internal damage or excessive heat, which can weaken the material. This condition can lead to hydraulic fluid leaks, which may pose serious safety risks, including loss of control of the machinery that the hose serves.

In maintenance and inspection practices, it is crucial to address blisters on hydraulic hoses promptly. Ignoring such signs can lead to catastrophic failures or equipment damage. Regular checks on hoses for bubbles or blisters should be a standard part of any pre-operation inspection to ensure the equipment operates safely and efficiently.
