What air couplings are available and what are they being used for?

By using an air coupling, you can quickly and simply connect and disconnect a hose or pipe. Our couplings are always made of high-quality materials, including anodized aluminum. The push button and valve is made of hardened stainless steel. All couplings are an important part of a compressed air system and ensure that compressed air is delivered safely and efficiently to machines and tools. It is therefore important to use only high-quality couplings and to inspect and maintain them regularly. To prevent leaks and further problems.

Here we give a brief explanation of the differences between the types of air couplings and how to use them. If you have any questions, please contact us. We are happy to help!

Push-in coupling

A push-in or push-in coupling for compressed air is a type of connection used to connect compressed air lines to machines or tools. These connections are designed to provide a safe and reliable connection between the compressed air line and the machine or tool. There are several types of compressed air insert couplings available, such as quick connectors, fittings and adapter couplings.

In this type of pneumatic coupling, the lines are connected by simply pushing them into the coupling. This is sealed by a special O-ring and locked by a toothed ring. When the release ring is pressed again, you can easily remove the hose from the insert coupling. This connection is different from traditional couplings, where the hoses must be connected with a nut system or connection via a click mechanism.

Push-in couplings are easy to use and offer a quick and safe connection for compressed air lines. All these couplings for compressed air are made of high-quality materials such as metal or plastic to ensure a safe and reliable connection. Moreover, they must be designed according to relevant standards and safety regulations to meet safety and durability requirements. Push-in couplings are available in different sizes and designs and become suitable for use in a wide range of industrial applications.

Quick release coupling

A quick release coupling for compressed air is a type of insert coupling used to connect or disconnect compressed air lines quickly and easily. Quick connectors are designed to provide a safe and reliable connection between the compressed air line and the machine or tool. There are several types of quick connectors available, such as couplers, adapter couplers and push-in couplers.

Quick release couplings are one of the most commonly used types of push-in couplings for compressed air. These connections are easy to use and can be connected and disconnected quickly and easily. Quick connectors are usually made of metal or plastic and are available in a variety of sizes and configurations. Quick connectors are also available with an automatic locking mechanism, which reduces the chance of leakage.

What is the difference between a Euro and Orion coupling?
Euro and Orion couplings are very similar, but there is quite a difference between them.

Orion couplings:

These have a smaller air passage, are made of nickel-plated brass and are especially popular in the Benelux countries, Switzerland and Sweden.Orion couplings are another popular type of quick connectors for compressed air. These are quick connectors with an automatic closing mechanism, which reduces the risk of leakage. Orion couplings are easy to use, have a low pressure drop, and are often made of metal or plastic. Orion couplings are also available in different sizes and configurations.

Safety coupling

A compressed air safety coupling is a type of push-in coupling designed to automatically disconnect when an unintended disruption or overload occurs in the compressed air system. These safety couplings are designed to prevent damage to compressed air lines or accidents resulting from a leak or overload.

Safety couplings are recommended to be used as an employer by meeting occupational health and safety requirements. When using safety couplings, you will not only work safely, it will also save energy costs. We recommend the use of hardened plug nipples in order to guarantee the lifespan of the safety coupling. The operation is simple, 1x press is for venting the hose, 2x press and the hose can be disconnected from the safety coupling.

A wide variety of safety couplings options are available to you, such as pressure-limiting couplings, pressure release couplings, and automatic release couplings. Pressure-limiting couplings are designed to automatically disconnect when pressure exceeds a certain threshold. Pressure release clutches operate by a pressure sensor that activates the release mechanism when an unintended drop in pressure occurs. Automatic disconnects are designed to automatically disengage when the flow of compressed air is unintentionally interrupted.

The safety couplings are available in Euro and Orion couplings with an air connection of ½ internal thread, ¼ external thread or 8 mm hose connection, for example. The maximum pressure is 10 bar, at 6 bar the coupling lets through 1600 l/min and can withstand temperatures between -20°C to + 70°C.

Threaded fitting

Threaded fittings are specially designed to connect pipes by means of a thread. This air fitting is used to connect compressed air lines to machines or tools. These fittings are designed to make a safe and reliable connection between the compressed air line and the machine or tool. Threaded fittings are available in:

 

• T-pieces (For splitting compressed air lines)
• Knee pieces (For an angle of 90°)
• Y-pieces (For the splitting of airways)
• X-pieces (For splitting, but also for straight routing of airways)
• Reducing rings (For connecting pipes of different sizes)
• Nipples (For connecting differently sized pipes)
• Plugs (Sealing of compressed airways)
• Sealing (for sealing of threaded fittings).

Threaded fittings for compressed air are available in various sizes, configurations and materials, such as brass, stainless steel and brass and are suitable for use in a wide range of industrial applications. Threaded fittings for compressed air are easy to install and remove, but it is important to make sure the fittings are connected correctly. What you need to think carefully about with threaded fittings are the sizes of the tubes. The wrong size can mean that it won't fit, which can cause leaks. What you also need to think carefully about is the airtight connection. You can achieve this by applying sealant to the pipe and the threaded fitting.

In case of oil or greasy environments, it is advisable to choose a fitting made of stainless steel or brass with a special sealant.

Straight hose connector

Straight hose connectors are used when you want to connect an air hose easily and quickly. The compressed air hose is pushed over the barb. This hose connector is ribbed to prevent the hose from slipping off easily. To clamp the whole thing even better, hose clamps can be used. Note that the diameter of the compressed air hose must match the diameter of the hose barb, otherwise it will not be tight and air will escape.

How to attach a coupling?
Always pay close attention to whether the size of the coupling or threaded fitting, fits the size of the pipe or hose. An incorrect size can mean that the two parts do not fit together properly and can therefore leak. You can achieve an airtight connection by applying sealant, such as thread sealant, Teflon tape or threadlocker to the pipe and thread fitting. To attach a coupling to a hose, we recommend using Teflon tape, but only on conical threads. On straight threads, use o-rings or threadlocker to make the connection airtight.

Below are some general steps for attaching a coupling:

1. Make sure the pipes are clean and dry before attaching the coupling;
2. Place the coupling in the correct position on the pipe. The coupling should be properly aligned with the pipes to prevent leakage;
3. Attach the coupling to the pipes by tightening the nut or snap mechanism. Make sure the coupling is securely attached;
4. When the coupling is attached, check that there is no leakage by testing the pipes with air pressure;
5. If using a safety coupling, check that it is functioning properly according to the manufacturer's instructions.

Keep in mind that depending on the type of coupling, there may be other steps to attach it
