how to install hydraulic hose fittings


Hydraulic systems are widely used in various industries for their efficiency and reliability. One crucial component of these systems is the hydraulic hose fittings. These fittings provide a secure connection between the hydraulic hoses and other components, ensuring the proper flow of fluids and preventing leaks. In this article, we will guide you through the process of installing hydraulic hose fittings, providing you with valuable insights and step-by-step instructions. So, let's dive right in!

Understanding Hydraulic Hose Fittings

Before we dive into the installation process, it's essential to have a clear understanding of hydraulic hose fittings. These fittings are designed to connect hydraulic hoses to other components such as pumps, valves, cylinders, and motors. They are available in various types, including straight fittings, elbows, tees, and couplings, each serving a specific purpose.

Finding the Right Fittings

The first step in installing hydraulic hose fittings is to ensure you have the correct fittings for your system. Hydraulic fittings come in different sizes and configurations, including British Standard Pipe (BSP), National Pipe Tapered (NPT), and metric fittings. Check the specifications provided by the hose and equipment manufacturer to determine the fitting size and type required for your system.

Gathering the Tools and Materials

To install hydraulic hose fittings, you will need a few essential tools and materials. Here's what you'll need:

1. Hydraulic hose

2. Hydraulic hose fittings

3. Hose crimping machine or fittings assembly tool

4. Adjustable wrenches

5. Lubricant

6. Safety goggles and gloves

Preparing the Hose

Before installing the fittings, it's crucial to prepare the hydraulic hose properly. Start by cutting the hose to the desired length using a suitable cutting tool. Ensure that the cut is clean and perpendicular to the hose axis to ensure a proper fit with the fittings.

Crimping the Fittings

Now that the hose is prepared, it's time to crimp the fittings onto the hose. Crimping is the process of compressing the fitting onto the hose using a crimping machine or fittings assembly tool. The crimping process creates a permanent and reliable connection.

Substep 1: Lubricate the fittings:

Apply a lubricant to the inside of the hose and the barbs of the fitting. This lubricant facilitates the insertion of the fitting into the hose and reduces the risk of damage during the crimping process.

Substep 2: Insert the fitting:

Insert the fitting into the hose until it reaches the end of the hose liner. Ensure that the fitting is fully inserted, and the hose overlaps the plastic core.

Substep 3: Position the assembly:

Place the hose and fitting assembly into the crimping machine or fittings assembly tool. Align the assembly within the crimping dies to ensure proper positioning.

Substep 4: Crimp the fitting:

Activate the machine to compress the dies around the fitting. Follow the manufacturer's instructions regarding the appropriate crimping diameter and pressure. Crimp all sides of the fitting to ensure a secure connection.

Inspecting and Testing

After crimping the fittings, inspect the assembly for any signs of leakage or irregularities. Check for proper crimping and verify that the fitting is securely attached to the hose. Additionally, conduct a pressure test to ensure the fitting can withstand the system's operating pressure without any leakage.

Installing the Assembled Hose

Once you've successfully crimped the fittings, it's time to install the assembled hose into the hydraulic system. Carefully connect the hose fittings to the respective components, ensuring they are correctly aligned. Use adjustable wrenches to tighten the fittings securely.

Regular Maintenance and Inspection

To ensure the longevity and performance of your hydraulic hose fittings, regular maintenance and inspection are crucial. Schedule periodic inspections to check for leaks, worn-out fittings, or damaged hoses. Replace any faulty components promptly to avoid system failures and potential hazards.


Installing hydraulic hose fittings requires careful consideration and adherence to proper procedures. By understanding the basic steps involved and using the right tools and materials, you can ensure a secure and reliable connection. Remember to follow safety precautions, consult manufacturer guidelines, and conduct regular inspections to maximize the lifespan of your hydraulic system.
