Hydraulic coupler - Hydraulic quick coupling

In the agricultural world, the hydraulic coupling is an indispensable tool for quick and safe connection and disconnection of your hydraulic systems. Whether screw-in, push-pull or suitable for high pressures, there are specific criteria to be met when choosing a coupling. How do you determine the right model? How to crimp it correctly? We address these questions and many more to help you make the right choice.

Understanding the role of hydraulic quick couplings

Hydraulic quick-release couplings play a crucial role in hydraulic systems, enabling efficient connection and disconnection of fluid lines. They are designed to minimize fluid loss and maintain a constant pressure optimal in the circuit.

These fittings are often used in a variety of working environments, such as agriculture, construction and manufacturing. Their design incorporates locking mechanisms that ensure a secure and rapid connection, even under high pressure.

Benefits include:

• Reduced maintenance time
• Improved safety thanks to non-return valves
• Ease of use with push-pull systems

These features make quick connectors an indispensable choice for meeting specific customer needs, guaranteeing both performance and reliability.

Hydraulic coupler types: push-pull, screw-in

Hydraulic push-pull couplings are particularly appreciated for their ease of use. They enable quick connection by simply pushing the two parts together, then just as easy disconnection by pulling them apart. This system is ideal for environments where tool changes are frequent, such as in the agricultural sector.

Screw couplings, on the other hand, offer a more secure connection. They are often used in applications requiring a solid, vibration-resistant connection. The connection is made by screwing the male coupling onto the female coupling, ensuring optimum sealing even under high pressure.

Here are just a few of the advantages of screw-in hydraulic couplings:

• Increased safety thanks to a fixed connection
• Vibration resistance and shock resistance
• Adapted to high-pressure conditions

These features make screw couplings indispensable for systems requiring maximum robustness and reliability.

Choosing the right flexible for its hydraulic coupling

To choose the right hose for your hydraulic connection, several criteria need to be taken into account. First of all, it's essential to consider the work pressure required for your application. Make sure the hose can withstand the maximum pressure without breaking.

Next, assess the operating temperature. Hoses must be able to withstand temperature variations to avoid premature deterioration.

Also take into account the inside diameter of the hose, which must correspond to the desired fluid flow rate. An inappropriate diameter can lead to pressure loss and affect system efficiency.

Here are a few points to check when making your choice:

• Hose material: rubber, thermoplastic, or metal
• Chemical compatibility with the fluid used
• Radius of curvature to avoid excessive bending

By following these recommendations, you will optimize the safety and performance of your hydraulic system.

Different sizes: 3/8, 1/2, 3/4

Sizes 3/8, 1/2 and 3/4 are commonly used in hydraulic systems for various applications. Each of these sizes corresponds to a specific fitting diameter, thus influencing the fluid flow rate and pressure supported.

For example, the 3/8 size fitting is often used for applications requiring quick and easy handling, such as hand-held tools. They offer a good compromise between flexibility and pressure resistance.

The 1/2 size is ideal for systems requiring higher fluid flow rates. It is frequently used in agricultural and industrial hydraulic circuits.

Finally, the 3/4 connection is suitable for high-pressure, high-flow applications. It is perfect for heavy equipment and systems requiring increased robustness.

Here is a summary of common uses:

• 3/8: portable tools, small equipment
• 1/2: agricultural hydraulic circuits, industrial applications
• 3/4: heavy equipment, high pressure and high flow rates

How to crimp a hydraulic hose

To crimp a hydraulic hose nipple, start by selecting the right nipple and skirt for your application. Make sure the diameter matches the hose specifications.

Next, cut the pipe to the desired length using a clean pipe cutter. Remove any residue or burrs from the ends to ensure optimum connection.

Then insert the skirt onto the pipe. Apply a light coat of lubricant to the nozzle to ease insertion.

Push the ferrule into the pipe until the collar is in contact with the skirt. Now place the whole assembly in the crimping press.

Check that the tool is correctly calibrated for the pipe diameter. Activate the press and crimp according to the manufacturer's recommended settings.

After crimping, visually inspect the connection to make sure it's tight and secure.
