Hose troubleshooting

Hose failure occurs for many different reasons. Your goal in troubleshooting is to identify the cause(s) then take the appropriate corrective action. Here are some examples of the most common hose failures with solutions on ways to correct or prevent them:

Abrasion

Solution - Reroute the hose to keep it away from abrasive sources and exposure to non-compatible fluids or guard the hose with a protective sleeve.

 

Hose burst at body

Solution - Check the pressure output of the system. It may be necessary to use a pressure transducer to measure the magnitude of any pressure surges. Select a hose that has the proper working pressure rating to handle the maximum pressure (including surges) of your application. Reroute hose to eliminate excessive flexing and/or exceeding the minimum recommended bend radius for the hose in use.

 

Hose burst at coupling

Solution - Increase assembly length to accommodate contraction of the hose under pressure. Increase actual bend radius as the hose exits the coupling. Bend restrictors can also be used to reduce bending stress at the coupling. Replace hose assembly with properly crimped assembly.

Cleanliness of your hydraulic system can greatly impact hydraulic system failure rates. European legislation aimed at creating the optimal conditions for success of your hose assemblies exists today.
