How to Repair A Hydraulic Hose? [5 Steps to Fix Hydraulic Hose]

Table of Contents


Today I am happy to share with you guys how to repair a hydraulic hose.


For the construction building, the hydraulic hose is basically important equipment used, and the hydraulic hose will be installed and applied for many types of vehicles, machines, and equipment, such as trucks, lift cranes, and other heavy-duty machinery, including building machinery, mine machinery, petroleum machinery and etc. 

The hydraulic hose is quite durable and reliable for the construction project, but you would find that some problems happen, such as wastage, spoilage, and breakdown because of long-time drive service life. 

Finally, the hydraulic hose would leak, or break as time goes by, resulting in some overloaded working problems, like decreased production, increased cost, and even some hazards to cause environmental pollution because of the hydraulic fluid leakage. 

So we have to find a way to repair the hydraulic hose if you find something abnormal on the hydraulic hose. 

Signs of a Damaged Hydraulic Hose

To determine whether a hydraulic hose needs repair, you must be aware of the common signs of damage. Conducting regular visual inspections can help you identify potential issues before they escalate. Here are some signs to watch out for:

  1. Visual inspection: Look for any visible signs of damage, such as cuts, abrasions, bulges, or blistering on the hose’s outer cover.
  2. Leaks and drips: Check for any fluid leaks or drips along the length of the hose. Leaking hydraulic fluid can indicate a compromised hose. You can click here to get more detailed info about leaking hydraulic hose.
  3. Decreased performance: If you notice a decrease in hydraulic system performance, such as slower movement or weaker force, it could be a result of a damaged hose.

Here are some easy steps to help you fix a hydraulic hose in the following:

Identify the Right Hydraulic Hose

Here are many different types of hydraulic hoses on the market, and heavy equipment will use different hydraulic hoses at the same time, because of the different functions required. And each hydraulic hose requires different pressure tolerance, so it is basically important to choose the right hydraulic hose for your equipment. 

Don’t install the wrong hydraulic hose with the wrong specifications for the hydraulic project, and keep in mind that it is very dangerous to use an incorrect hydraulic hose, even temporarily. Please be serious about selecting the hydraulic hose. And don’t hesitate to consult your hydraulic hose engineer if you have any questions about the hydraulic hose selection. 

Remove the Damaged Hydraulic Hose

If you finish the hydraulic hose selection step, and then you need to remove the damaged hydraulic hose from the hydraulic equipment, to cut off the damaged area of the hydraulic hose pipe. If you find the hydraulic hose is leaking, you have to remove the whole hydraulic hose with the leaking hole. 

And then you need to clean the hydraulic hose removed, to make it tidy and clean, without any dirt, dust, oil contamination, or greasy dirt. Because dirt like this could contaminate the hydraulic fluid, making it unpure. 

So please be sure that the hydraulic hose and hydraulic hose fittings are clean before proceeding to repair the hydraulic hose. 

Seal Hydraulic Hose

Don’t forget to wrap the hydraulic hose using the spiral hose guard, or fire sleeve to protect the hydraulic hose after the maintenance process. Choosing the right hydraulic hose protector can keep the hydraulic hose stay safe during its service life, and it is also important to expand the hydraulic hose life span, up to 3-5 years. 

If you have some questions about the selection of a spiral guard for the hose, or fire sleeve protector, please feel free to contact us at any time if you need help. 

Consult Hydraulic Hose Protector

Replace A New Hydraulic Hose

After identifying the warning signs of the hydraulic hose breakage, then you need to replace a new hydraulic hose after removing the bad one. And a hydraulic hose adapter is required to install the repaired hydraulic hose. The memo is that you need to prepare some substitute hydraulic hoses in your toolbox for hydraulic hose replacement if needed. 

Please choose the right length of the hydraulic hose, longer is much better than shorter. You can cut off the damaged area once if you find some problems in a certain area. 

During the installation, please use the proper wrench to screw the new hydraulic hose to the hydraulic equipment, and you can install the hydraulic hose fittings to the hydraulic hose pipe head before installing them to the machine. 

Screw the hydraulic hose fittings in the opposite direction using the wrenches to tighten the hydraulic hose fittings, to avoid the hydraulic hose would get loose in the future. 

Check Hydraulic Hose Pressure

The checking step is also important, you need to check the hydraulic pressure using the pressure gauge or pressure meter to test if the hydraulic hose can work well. 

Please turn on the hydraulic system to let it work to simulate the daily working status, and then circulate the hydraulic fluid at low pressure. This method can recognize the leaking position of the hydraulic hose, to find the potential leaking points or other damaged areas. 

How to Patch a Hydraulic Hose

To patch a hydraulic hose, you will need a few tools and materials. Here’s a step-by-step guide on how to do it:

  1. Safety First: Ensure the hydraulic system is turned off, and relieve any pressure in the system by activating the control valve multiple times.
  2. Identify the Damage: Locate the damaged area on the hydraulic hose. It could be a hole, cut, or a leak. Inspect the hose thoroughly to determine the extent of the damage.
  3. Gather Materials: You will need a hose patching kit, which typically includes a hose clamp, hose mender, and a coupling. These kits can be purchased at hardware stores or hydraulic supply shops. Make sure to get a patching kit that matches the size and type of your hydraulic hose.
  4. Cut and Remove the Damaged Section: If the damage is extensive, you may need to cut out the damaged section using a sharp utility knife. Make sure to leave enough hose length to work with.
  5. Clean the Hose Ends: Use a clean cloth or rag to wipe the ends of the hose that you just cut. Remove any dirt, debris, or oil that could interfere with the patching process.
  6. Install the Hose Mender: Slide the hose mender into one end of the hose. Make sure it fits securely and snugly. If necessary, you can apply a small amount of lubricant to ease the installation.
  7. Secure with Hose Clamp: Place the hose clamp over the mender and align it in the center of the mender. Use a screwdriver or a wrench to tighten the clamp securely. Ensure it is tight enough to prevent leaks but not so tight that it damages the hose.
  8. Test for Leaks: Turn on the hydraulic system and carefully inspect the patched area for any signs of leaks. If you notice any leaks, tighten the hose clamp further or consider rechecking the installation process.
  9. Recheck and Reinstall: Once you are confident that the patch is holding up well and there are no leaks, recheck the entire hose length for any other potential weak spots or damage. If necessary, consider reinforcing those areas with additional clamps or menders.
  10. Safety Check: After completing the patching process, turn off the hydraulic system, and perform a final safety check to ensure everything is in order. Clean up any debris or tools used during the process.

It’s important to note that patching a hydraulic hose is a temporary solution, and it’s recommended to replace the damaged hose as soon as possible. Patching should only be done when you don’t have immediate access to a replacement hose or as a temporary fix until a replacement can be obtained.

Of course, we need to test the leaking problems, again and again, to ensure that the hydraulic system can work well without any leaking problems. 

How Do You Fix a Hole in a Hydraulic Hose?

Fixing a hole in a hydraulic hose is a complex task that requires specific knowledge and tools. Often, due to the high pressures in these hoses, it is more safe and effective to replace the hose instead of attempting to repair it.

However, if a replacement isn’t immediately available and a temporary repair is needed in an emergency situation, you could follow these general steps:

Materials Needed:

  • Hydraulic hose repair kit (This typically includes a cutter, fitting, crimping tool, and a set of dies)
  • Safety gloves
  • Safety goggles
  • Hose guards or sleeves


  1. Safety First: Always make sure to depressurize the system before you start working on it. Remove the hose from the system and make sure there’s no pressure left in it.
  2. Identify the Damage: Locate the exact position of the hole.
  3. Cut the Hose: Using a sharp cutter from the repair kit, cut the hose at the damaged area. Make sure the cut is clean and straight.
  4. Prepare the Ends: Remove the outer cover of the hose to expose the steel wire braid around the hose. Then remove the wire braid to expose the inner layer of the hose.
  5. Install the Fittings: Take the new fittings from the repair kit and insert them into the ends of the hose. Make sure they’re inserted all the way in.
  6. Crimp the Fittings: Using the crimping tool and the appropriate die, crimp the fittings onto the hose. This will secure the fittings onto the hose and ensure a good seal.
  7. Inspect: Make sure there are no sharp edges or loose parts. Also, double-check the crimp to ensure a secure fit.
  8. Reinstall: Put the repaired hose back into the system. Be cautious while repressurizing the system and monitor the repair site for any signs of leakage.

Remember, this is a temporary fix and the hose should be replaced as soon as possible.

Also, keep in mind that working with hydraulic systems can be dangerous due to the high pressures involved. Always follow safety guidelines and if you’re unsure about the process, consider hiring a professional.

Can You Fix a Hydraulic Hose With Tape?

No, you cannot fix a hydraulic hose with tape.

Hydraulic hoses operate under very high pressure, and a tape repair wouldn’t be able to withstand that pressure. Attempting to fix a hydraulic hose with tape could result in a catastrophic failure and potential injury when the hose is pressurized.

Tape might temporarily stop a leak, but it is not a safe or long-term solution. It’s important to replace a damaged hydraulic hose as soon as possible to prevent further damage to the hydraulic system and ensure personal safety.

If a hydraulic hose is leaking or damaged, it should be properly repaired or replaced by a professional or someone who is trained to do so. Working with hydraulic systems can be dangerous due to the high pressures involved, so it’s important to always follow safety guidelines.
