Pneumatic Fittings

Pneumatic fittings – a type of special connecting devices used to connect pneumatic hoses together, as well as to connect them to pneumatic tools and equipment.

In pneumatic systems, reliable sealing plays a major role. Connecting fittings – pneumatic fittings – applicable in structures that pump previously filtered air, as well as when working with gases and aggressive working environments.

Fittings for pneumatic systems: materials and types

The connecting elements of the system can be made from:

• brass and copper, as well as on chrome, nickel and Teflon base;
• stainless steel, which has excellent corrosion resistance, especially in aggressive environments;
• polymer materials, which ensures high strength of the product;
• combined options, which involve the use of both metal and plastic inserts.

Pneumatic connectors, based on their structural characteristics, can be divided into:

• direct – for joining hoses with the same diameters on a straight section of the structure;
• angular – to change the direction of the entire structure at a certain angle;
• tees – to branch the main thread;
• transitional – for joining pipes of different diameters;
• connectors – for joining hoses having the same or different threaded sections, as well as made from different materials;
• plugs – for plugging in the end hole system.

To create a unified pneumatic system, connecting fittings are used, which, according to the connection method, are divided into the following types:

1. Collet-type pneumatic fittings – They are used for frequent dismantling and are also suitable for assembling a stationary system. Their design includes a fitting, a nut and a ferrule.
2. Fittings with union nut – are tightened onto the tube by hand, which is tightly fixed in the area of the receiving fitting. These elements are used to join several hoses or to connect them to a pipeline.
3. Crimping pneumatic fittings – secures the tube by means of a clamp between the nut and the fitting itself. Mainly applicable to plastic hoses.
4. Installation of nipple connectors is often carried out on pipelines when it is necessary to add branches, change the direction of flow, or provide a turn.
5. Threaded elements – detachable parts that are installed in places not intended for dismantling.
