Connecting two hydraulic Tubes is a fundamental operation in any hydraulic system, whether industrial, agricultural, or domestic. A proper connection ensures the system’s seal, prevents leaks, and guarantees a smooth fluid flow. However, to achieve optimal results, it is necessary to use the right components and follow the correct procedures. Here is a guide that explains how to connect two hydraulic Tubes, the necessary components, and the best practices for a safe and efficient connection.

What components are needed to connect two hydraulic Tubes?
Hydraulic fittings
Hydraulic fittings are essential for joining two Tubes. There are different types of fittings, each designed for specific applications and Tube types:
- Threaded fittings: Equipped with internal or external threads, they are used for secure and durable connections.
- Compression fittings: They use a compression ring to create a leak-proof seal around the Tube.
- Flange fittings: Ideal for high-pressure applications, these fittings provide robust and reliable fastening.
Seals
Seals, such as O-rings and washers, are crucial for ensuring connection tightness and preventing leaks. It is important to choose seals compatible with the hydraulic fluid used in the system.
To make the connection, specific tools may also be required, including:
- Torque wrenches: To ensure proper tightening without damaging the fittings.
- Tube cutters: To cut the Tubes to the desired length without deforming them.
- Lubricants: To facilitate fitting insertion and reduce seal wear.
Procedure for connecting two hydraulic Tubes
Before starting, ensure the Tubes are the correct length and free of damage or impurities, then cut the Tubes with an appropriate Tube cutter, avoiding uneven edges that could compromise the seal. Finally, verify that the fittings and seals are compatible with the Tubes and the hydraulic fluid.
1- Fitting assembly
For assembly, start by inserting the seal into the fitting, ensuring it is properly aligned.
Then connect the fitting to the first Tube, inserting the end of the Tube into the fitting and tightening with a torque wrench to ensure a secure connection.
Next, connect the other fitting to the second Tube following the same procedure.
2- Final assembly
To assemble everything, join the two fittings already attached to the Tubes. Be careful to tighten adequately, using appropriate tools, to avoid over-tightening that could damage the threads or seals.
Practical tips for a secure connection
After completing the connection, test the system to check for any leaks. Turn on the hydraulic system and carefully observe the connection points. If leaks are detected, turn off the system and check the fitting tightness and seal integrity.
To ensure system longevity, it is advisable to periodically inspect the fittings and seals and replace any worn or damaged components to prevent failures and improve system efficiency.
