The most common causes of hydraulic hose failure are:

Abrasion: Hose assemblies may come into contact with abrasive surfaces, causing the outer covering of the hose to wear down and eventually lead to leaks or bursts.

To minimize abrasion, some hoses have plasticizers added to the material that makes up the hose cover. If there are specific problem areas, a plastic guard or nylon sleeve can be used to protect the hose.

Excessive Pressure: Operating hydraulic systems at pressures beyond the recommended limits can cause hoses to rupture or burst. It is essential to ensure that the system operates within its specified pressure range.

Twisting or Kinking: Twisting or kinking a hydraulic hose during installation or operation can lead to damage to the inner lining and reinforcement layers, causing the hose to fail.

Improper Installation: Incorrect installation of hydraulic hoses, such as using the wrong size or type of fittings, can result in leaks or hose failure. The hose clamps or fittings should be correctly tightened, and the hose should be properly routed to avoid excessive bending or strain.

Chemical Compatibility: Some hydraulic systems may contain fluids that are incompatible with the hose materials. Exposure to these fluids over time can cause deterioration and failure of the hose.

Age and Wear: Over time, hydraulic hoses can experience degradation due to aging, exposure to the elements, or regular wear and tear. It is important to regularly inspect and replace hoses that show signs of degradation, such as cracks, bulges, or leaks.

High Temperatures: Operating hydraulic systems in extreme heat can cause the hose material to deteriorate, leading to failure. It is crucial to use hoses that are suitable for the temperature range of the system.

Regular inspection, maintenance, and proper usage of hydraulic hoses can help identify and prevent potential failure, ensuring the safe and efficient operation of hydraulic systems.
