Signs that your hydraulic hose assembly needs replacing

Hydraulic hose systems are found throughout the industrial manufacturing industry. They are found in many applications, from pump stations to braking systems for vehicles. As with anything, they have a lifespan and whilst incredibly durable, even the best maintained hoses will degrade and suffer from wear and tear. How long a hose assembly lasts depends on several factors, including the environmental conditions it is in. So, how do you know if it’s time to repair or replace a hydraulic hose system?

You notice oil leaks

Repeatedly noticing oil leaks is a common sign that all is not well with your hose system. It might not be the only thing wrong, so it’s important to check that isn’t something can be easily repaired before replacing.

It could be a leaky O-ring that needs replacing and not the entire hose assembly. Oil leaks can also be caused by an overly tight connection. Have a good look at the hose assembly and if it looks ok but is still leaking oil, it’s probably time to replace the assembly. For Silicone Hose Manufacturers, visit goodflexrubber.

Wires that are exposed

Inside hydraulic hoses are internal layers of wiring that provide additional support and flexibility. Over time, the external coating will wear away, exposing the internal wiring underneath. If you see this occurring, it’s time to replace your assembly.

Cover damage

It is not unusual to see scratches and scuffs on the outer casing of hydraulic hosing. However, if you’ve spotted this on the last few checks you’ve made, it could be time to replace it. If excessive deterioration is occurring, your hose could fail.


If you notice kinks and twists in the hosing, this can pose a threat as pressure builds up inside the hose. Any fluid running through must be able to so freely. If kinks are present, there is an increased risk of the hose bursting and oil leaks occurring. Blown hoses are often caused by twists, kinks, crushing and scrapes.

To protect the lifespan of your hydraulic hoses, ensure a regular maintenance plan is in place. By not checking it regularly, you increase the risk of a very costly problem occurring which could cost far more than a simple hose assembly replacement.

It’s important to always make sure the assembly is put together properly. A system that’s not fitted correctly can result in hoses whipping out of control and possibly injuring workers.

Any spills that might occur, such as oil leaks should be cleaned up immediately to reduce the risk of falls and slips. It’s also important to carry out regular checks of other components too, such as motors and pumps. If just one component is faulty, it can negatively affect the whole system.

Completing a monthly visual inspection is advised, as well as replacing your hose assembly approximately every two to three years, or when excessive wear is noticed.
