When should you replace your hydraulic hose

This article works on when should you replace your hydraulic hose and some tips on how to replace them.

Using damaged or worn-out hydraulic hoses in your hydraulic systems is a disaster waiting to happen. Fluid leaking is one of the main risks of using such hoses, as the hydraulic fluid is usually hot.

When such hot fluid comes in contact with the skin, you risk suffering burns, skin poisoning, or other serious skin infections. It is also possible that different parts of your hydraulic system get damaged.

Furthermore, it is against industry regulations not to replace worn-out hydraulic hoses. The consequences of going against these regulations include fines, lawsuits, or the closure of your factory.

To avoid all of these problems, you need to know when to replace your hydraulic hose. In this post, we’ll look at the signs that show your hose needs replacement and the steps involved in replacing hydraulic hoses.

4 Signs that a Hose Needs Replacement

Regular inspection and preventive maintenance help you detect if there is a problem with your hydraulic hose and system in general. When you next carry out an inspection, watch out for these four signs to know if your hose needs replacement or not:

1. Fluid Leaks

The primary purpose of hydraulic hoses is to convey pressured fluid from one component to the other. When you notice fluid or oil leaks around your hydraulic hose, it means it’s not doing its job. What it also means is that the hose has a puncture.

Sometimes, detecting these punctures is difficult since they are usually tiny. However, larger holes frequently occur with old hydraulic hoses, and when you notice such, it is time to replace your hydraulic hose. However, there are two leading causes of fluid leaks in a hydraulic system – abrasion and improper assembly. If it’s a new hydraulic system, confirm if the hose was set up correctly before considering replacing it if it is a new hydraulic system.

2. Crushed Hoses

Crushed or knitted hoses are common causes of accidents with hydraulic systems. This is because they lead to increased pressure, which weakens the strength of your hydraulic hose. Therefore, when you notice this with your hydraulic hose, replacing the hose should be a priority.

Crushed hoses happen when your hydraulic hoses are constantly in contact with other objects in the system. Over time, these other objects, especially the heavier ones, press on them and ultimately causes damage. Crushed hydraulic hoses also cause fluid leaks in some cases. One way to prevent this is by properly installing and routing your hydraulic hose from the onset.

3. Exposed Wire

If your hydraulic hose suffers from abrasion, it develops cracks with time. However, if it is a difficult situation, the cracks often give way and result in an exposed wire.

A hydraulic hose with an exposed wire is unreliable in transporting pressured fluid, just like crushed hoses. Over time, it leads to leakage, which is harmful to people and other equipment around the hydraulic system. As a result, hydraulic hoses with exposed wires need replacement. More often than not, severe abrasion that causes exposed wire happens with low-quality and old hydraulic hoses. Irrespective of which it is, getting a new, quality hose for your hydraulic system is a priority. In particular, go for abrasion-resistant hydraulic hoses to prevent this problem.

4. Cracked Fittings

Hydraulic fittings

Hydraulic hoses depend on hydraulic fittings to function correctly. If the fittings are not tight enough, they leak around the connection point with the pipes or tubes. This is typical with cracked or corroded fittings.

Why not change the cracked fittings and retain the hydraulic hose? Well, you don’t always have to replace your hydraulic hose when you notice cracked or corroded fittings. However, the leakage caused by the fittings sometimes damages the hose ends.

When this happens, most people simply cut off the damaged part of the hose and use it with a new fitting. However, doing that is not always safe if the damage is significant. In such cases, it is best to replace the hydraulic hose.

What is the lifespan of a hydraulic hose?

Hydraulic hoses come with an expiration date from the manufacturer. However, the average lifespan of a hydraulic hose is at least five years. With proper maintenance, you can extend the lifespan of your hydraulic hose to a year or two more. However,

Steps for replacing hydraulic hoses

While replacing hydraulic hoses, following the proper steps is crucial to be sure you’re replacing the correct hose. Here’s what to do:

  1. Note what type of damage occurred. Damages prompt hydraulic hose replacement, and identifying what damage you’re dealing with helps ensure you purchase the correct replacement hose. For example, an abrasion-resistant hose is ideal if the replacement is due to an exposed wire.
  2. Check other nearby equipment. Leaks from damaged hydraulic hoses threaten other nearby equipment. Suppose the others are damaged too. In that case, they require replacement also, or else the new hydraulic hose won’t work correctly.
  3. Prepare your hydraulic system. Preparing your hydraulic system simply means ensuring it’s not operational during the replacement process. Disconnect all system parts attached to the hydraulic hose – fittings, for example – and create a clear working area.
  4. Dispose of the damaged hydraulic hose. After disconnecting the parts attached to the hose, remove it from the hydraulic system and drain any residual fluid. Then, dispose of the old hose properly.
  5. Install the new hydraulic hose. In this fifth stage, install the replacement hose following the manufacturer’s recommendation. Getting a professional for the installation is also viable if you find the procedure intricate.
  6. Test the new hydraulic hose. Finally, test the new installation to confirm it works accordingly. Review the hose performance during and after the test, and most importantly, watch out for leaks.
