How To: Step-by-Step Look at Hydraulic Hose Assembly

Reading Time: 3 minutes

Hydraulic hoses can be purchased as prefabricated products, but they may not serve your exact purposes. At Motion & Flow Control Products, we understand that customized hoses are almost always required in most industries. Streamline your company’s machines with hoses made in-house. Follow this simple, step by step guide to making hydraulic hoses with expert results.

1. Prep the Hose and Fittings

Prepare a hose saw with the proper cutting edge first. It should provide a clean cut through any size hose. Measure out the length of hose that you need, which includes the cutoff factor that comes in at the end of the process.

Cut the outer covering of the hose with the saw. Take a close look at the hydraulic hose assembly. The cut edge should be smooth. Be sure to file down the edge so that any deformity is removed from the material.

Select a fitting for the hose that matches the size and brand name. Mixing materials isn’t recommended.

2. Attach the Fittings

Make use of a hose insertion depth block in order to verify the insertion depth on the fittings. Hydraulic hose fittings must be properly attached because leaks and bursts can be commonplace in this area, according to the Wyoming Department of Workforce Services.

Follow these guidelines when attaching the fittings, including:

  • Indicate the insertion depth with chalk on the hydraulic hose assembly
  • Lubricate the hose unless it’s a spiral type
  • Press the fitting into place
  • Verify that it meets the marked line

3. Set up the Crimping Machine

Learning how to crimp hose is an art itself. Get familiar with your particular machine. Be aware of its capabilities when it comes to crimp diameter. It must be set to a precise value. Without correct diameters, the hose crimper produces either a loose or extremely tight endpoint that’s vulnerable to leaks.

Go over your die sets. Pick out the right match for your fitting-and-hose assembly. Ideally, the machine will crimp all of the main parts to create a seamless construction, reports Hydraulics & Pneumatics. With the machine set up in the proper manner, you can move forward with your project.

4. Insert and Crimp Hose

This step by step guide involves the use of a crimping machine for both spiral and braided hoses. Insert the fitting to be crimped into the machine. The fitting should rest just above the die. Attach the compression ring if your assembly requires it.

Put on all of your safety gear before activating the machine. Caution with heavy machinery is always the best choice.

Turn on the machine. Allow it to perform its work. The crimping should be practically perfect after this process.

5. Check and Clean the Hose

As you learn how to make hydraulic hoses, you understand that precision is key. Remove the hose assembly from the machine. Inspect the fitting and hose. The indicator mark should still be visible where it connects the two assemblies together.

Crimp the hose again if the mark is either off or lost under the fitting. Proceed to clean the assembly when the connection is good. Compressed air and projectile pellets are good choices as cleaning tools. Be sure to clear out the pellets’ residue if you select this agent.

6. Cap it Off

Regardless of the hose’s future use, it’s always necessary to use seal caps on the final assembly. You don’t want any contaminants finding their way into the hose. Ideally, use a heat-shrinking process to cap off the ends. You can store the assembly for as long as necessary, and no contaminants will find their way into the length. Protecting your hydraulic system starts with hose creation.
