What Are The Hydraulic Hoses?

Hydraulic hoses are the medium to transport hydraulic fluid between any components. In the hydraulic system, hoses are as important as hydraulic because there is no use of hydraulic without hydraulic hoses, hydraulic hoses in the hydraulic system transport hydraulic fluid between two or more components. The life span of the hydraulic system can be increased by properly installing hydraulic hoses along with good efficiency. Our main goal in this article is to provide you with the step by step instructions and the easiest way to hook up hydraulic hoses. So without wasting any further, let’s directly jump into the main topic.

Step 1:  Preparing The Tools

Do you know how many tools are required to connect hydraulic hoses with hydraulic systems? If not, here are all the tools you will need to connect hydraulic hoses. 

  • Hydraulic Hoses.
  • Hydraulic Fittings.
  • Wrenches.
  • Rags
  • Thread Sealing Tape.
  • Hydraulic Fluid.

If you have all the above-mentioned equipment, then you are ready to go.

Step 2: Identifying Hose Type and Fitting

First of all, you have to ensure the hoses and fittings match in terms of shape, size, and thread. If you don’t know about hydraulic hoses and fittings then you can get information from hose and fittings specifications. There are many types of hydraulic hoses, and it’s really important to identify the type before connecting them to the hydraulic system. Here are some of the specifications you need to know before hooking hydraulic hoses to the system.

  •  Pressure Rating

Pressure Rating means the maximum pressure the hoses and fitting can handle safely. Do you know what’s the appropriate pressure rating for your vehicles? If not, then ask the company and choose hydraulic hoses accordingly.  

  • Temperature Range

Temperature Range means the maximum temperature that the hydraulic hoses and the fitting can handle and operate it safely. The hydraulic hoses should always be able to handle the temperature of your hydraulic fluid, so choose hoses and fittings accordingly.

  • Compatibility

We all know every fluid has different chemical properties. That’s why it’s always important to choose hydraulic hoses and fittings that are compatible with the hydraulic fluid. If you fail to choose the proper fluid that is compatible with your hydraulic, then over time, it can cause hoses and fittings to degrade.

  • Diameter and Size

Using an unmatched-size hose or fitting is the main reason for leaking and damaging the system, and many times, it’s the reason for the deadliest accidents. Before trying to connect hydraulic hoses, make sure the size of the hoses and fittings match the size of the control valve and pump.

  • Connector Type

Crimp fittings, JIC fittings, and ORFS fittings are examples of the several types of connectors for hydraulic hoses. The connector must match the fittings of your vehicle, so choose accordingly.

If you still have any questions about the type of hydraulic hoses and fittings then you can contact the manufacturer to determine the correct ones.

Step 3: Cleaning The Connection Points

Both points on the hose and fitting must be cleaned before connecting. Many times dirt, rust, or other materials cause problems. That’s why using a rag to remove dirt is always a good step. If you are replacing the old hydraulic hoses, then you should remove the old hoses and clean the connection points. You can either use a clean rag, wire brush or simply whatever you prefer to clean dirt or rusting. Make sure the new hoses are in good condition before making any changes.

Step 4: Applying Thread Sealing Tape

Thread sealing tape is used to wrap the threads of the fitting, and it will help to ensure a tight seal and prevent any leakage. This thin, flexible white thread sealing tape has many other names like PTFE or Teflon tape. This tape is perfect for filling gaps and preventing leaks because it’s made of a flexible material.

Step 5: Attaching The Fitting To The Hose

Take a wrench, and screw the fitting onto the hydraulic hose until the fitting is secured tightly. The fitting should not be over-tightened because it can damage the hose or the fitting.

Step 6: Checking For Leaks

Now it’s time to check the hydraulic hose leaks and apply a small amount of fluid to the connection points after the fitting has been completed. No leaks mean you are ready to proceed to the next steps, and if there are any leaks check for incorrect attachments and thread damage.

Step 7: Repeating The Operation 

Now repeat step no.6 for 6/10 times. If everything is going well, then you are ready to proceed to the next step.

Step 8: Filling The Hydraulic System With Fluid

As a last step, it’s time to fill the hydraulic fluid according to the manufacturer’s guidelines. Make fluid level need to be exact, not high nor low.


If you follow the above-mentioned instructions, you will find no difficulty connecting hydraulic hoses. You can contact your manufacturer for any queries, we are always here to help you in case you need us in the future.

In the above, we have focused on the steps to connect hydraulic hoses, and we are pretty sure we have listed all the necessary information, but in case you find we have overlooked something important, please let us know.
