How to Replace A Hydraulic Hose? [Hydraulic Hose Replacement Guide Step by Step]

Table of Contents


As we all know that the hydraulic hose has a wide application, and today I am going to share with you that how to replace a hydraulic hose.


Here are many types of heavy machine equipment used for the construction, working for the hydraulic projects. In the hydraulic system, the hydraulic hose is working great in the fluid conveying process.

The hydraulic hose is basically important equipment to convey various fluids, including oil-based fluids, water-based fluids, and petroleum-based fluids, so you can’t work for the hydraulic project construction without the help of a hydraulic hose.

As time goes by, the hydraulic hose could become aged, fossilized, old, and the function of the hydraulic hose will become much duller, heavy-headed. So the hydraulic equipment can’t work properly because of degraded hydraulic hose.

The old hydraulic hose will cause some problems, such as fluid leaking, oil bursting, and many other potential problems, being damage to the whole construction project, and we have to replace a new hydraulic hose to recover the project construction again.

Let’s start to learn how to replace a hydraulic hose to upgrade the hydraulic hose to the next level.

When to Replace a Hydraulic Hose?

Here are some symptoms telling you that the hydraulic hose is aged, and it needs to be replaced.

You can see the obvious breakage from the cover of the hydraulic hose.

You can hear the noise while the hydraulic project is working, so please be cautious about the abnormal noise.

And then you also need to renew the hydraulic hose if the hydraulic hose has been used for a long time, it will cause mechanical aging problems.

All of these problems happen, it is time to replace the hydraulic hose, to update the hydraulic construction project.

Remove Damaged Hydraulic Hose

The first step to replace a hydraulic hose is to remove the damaged hydraulic hose.

Things you need to prepare before removing the hydraulic hose.

The hydraulic fluid is toxic, so it could do damage to your skin when you contact the hydraulic hose closely. Please put on goggles and gloves to protect yourself, away from the hydraulic fluids. Don’t take them off until your hydraulic hose replacement is finished.

And you can wear old clothing or special clothing to protect your body, without any touches to the hydraulic fluids directly. The long sleeves and pants are better to be taken to your consideration because these clothing can cover your skin to the maximum.

A mask or respirator is also needed if you are not working in a well-ventilated place. Don’t make the hydraulic fluids get close to your eyes, or mouth. In a word, personal protection is basically important.

Release Hydraulic Pressure from Hydraulic System

Then you need to release the hydraulic hose pressure from the hydraulic hose. Never ever work on the hydraulic machine if there is pressure in the hydraulic hose because the hydraulic fluid is dangerous to people’s safety.

High hydraulic pressure left in the hydraulic hose system is hazardous, resulting in some problems, such as spraying, bursting, and etc. So please be cautious about the hydraulic pressure before working on the hydraulic system. And the spraying hydraulic fluids will hurt you.

Here you can use different equipment to relieve the hydraulic pressure. For example, you can use the hydraulic fluid relief valve to depressurize the hydraulic hose. If you are confused about the relieving hydraulic pressure, don’t be sorry to consult the hydraulic hose technicist.

The common thing is that the hydraulic depressured tool will have a lever, that will help release the hydraulic pressure of the hydraulic project. So start the lever of the lever hydraulic fluid relief valve first, and then shut off the power to the hydraulic line.

Then make the hydraulic lever back, to let the hydraulic pressure out. So please remember that release the hydraulic hose at the beginning.

Keep A Can under Hydraulic Hose When You Remove

The hydraulic fluid will leak out of the hydraulic hose while you remove it off. So please place a can or bucket under the hydraulic hose while removing, to collect the hydraulic fluid as it leaks. It’s much better to prepare a bucket with a big depth to avoid the hydraulic hose spray.

What’s more, you can also lay some rags, or tatters underneath the bucket to avoid the hydraulic fluid pullet the ground or floor, because it is much harder to clean the hydraulic fluids compared with water, juice, or other fluids.

Remove Hydraulic Hose Covering

Then please remove the covering of the hydraulic hose. We usually like to apply the spiral hose guard, or fire sleeve to protect the hydraulic hose to protect it away from potential harm. So you need to remove them off while removing them from the hydraulic system.

At the same time, you can use your cellphone to take pictures to show each step of your work, in order to track everything you remove, which can help you remember how to get them back to the hydraulic hose system like before. Things needed are different in each step.

And you can also clean up the hydraulic hose connectors, to remove all dirt, dust, oil from them. You can feel much happier when you see the tidy hydraulic equipment. That’s it.

Remove Hydraulic Hose Fittings

And then you can use the wrench to unscrew the hydraulic hose fittings from the hydraulic hose. The hydraulic hoses are screwed together by the hydraulic fittings, you need to loosen them to unscrew the fittings off the hydraulic hoses. Spin the wrench in the opposite direction to remove the fittings.

At the very beginning, you need to use the right wrench with the right diameter and jaw to bite the hydraulic fittings well, and then remove off from the hydraulic hoses.

Install A New Hydraulic Hose

Next, you need to use a new hydraulic hose to replace the old one. It is important to find the correct hydraulic hose to match the hydraulic system, with the same specification, diameter. And then check the pressure rating on the hydraulic hose, usually, you can see the marked pressure rating on the cover of the hydraulic hose.
If you have any questions about the specifications of the hydraulic hose, please feel free to contact us, or you can look for a local hydraulic hose store to help you with this. It is very important to select the right hydraulic hose, to replace your old one.
What’s more, if you need hydraulic hose crimping, please go to the store to find the hydraulic hose technique to crimp the hydraulic hose for you, they will have the hydraulic hose crimping machine to do this.
Then you need to use the wrench to screw the hydraulic hose back to the hydraulic system. Choose the right hydraulic fittings at first, and then use the wrench to rotate it clockwise to tighten it, until the hydraulic hose stop spinning.
Finally, don’t forget to wrap the hydraulic hose with the spiral hose guard protector, or hose protect sleeve to protect your hydraulic hose, this can help a lot to expand the service life of the hydraulic hose, up to 3-5 years.

Test Hydraulic Hose

Don’t forget to use the pressure meter to test the hydraulic pressure after you replace the hydraulic hose. You can test the hydraulic pressure at any time if you think it is the key point, to double-check the pressure can ensure that you install the hydraulic hose in the right way.

The hydraulic hose replacement can be finished if there is no hydraulic fluid leaking problem, with the right range of hydraulic pressure as marked on the hydraulic hose.

Hydraulic Hose Replacement Tips

Here are some useful tips for the hydraulic hose replacement in the following:

  • Keep it clean: Cleanliness is the first basically important thing you have to keep in your mind, you need to clean the critical parts of the hydraulic working system to keep the machine in a good condition all the time. The dirt and dust will cause the hydraulic hose failure,  due to the chemical breakdown or friction resulting from the hose pollution.
  • Update hydraulic hose regularly. Please check the working pressure of the hydraulic hose from time to time, to ensure the hydraulic hose can work in a healthy and safe condition all the time. If you find something abnormal, like hydraulic fluid leaking, hydraulic hose aging issues, hydraulic hose twisting and etc, please replace it with a new one right now. The newer the better, don’t delay the visible problems to cause some more potential damages.
  • Choose the right tools: Here are different hydraulic hose tools needed during the process of hydraulic hose installation or replacement, please serious about getting the right hydraulic hose tools. Like the right hydraulic hose crimping dies to crimp hydraulic hose, wrenches to connect hydraulic hose fittings, hydraulic hose cutting blade to cut the hydraulic hose and etc. In total, the right tools are important all the way up.
