Choosing the Right Pneumatic Fittings

You’ll typically find a wide range of pneumatic fittings in the market. The problem, however, is choosing the right one for your pneumatic system. To make the right decision, you need to be aware of the functional air pressure, the tubing being utilized, the thread type of the receiving fitting (if any) and the amount of vibration tolerable by the fitting.

Common types of pneumatic fittings

Here’s a list of different types of pneumatic fittings to help you choose the appropriate one:

Compression Fitting 

All types of pneumatic fittings that use compressive force to make secure connections to the vessel are referred to as compression fittings.

These fittings rely on outer compression nuts that screw down over the ferrule and compress it. The compression causes the ferrule to bow inwards, in turn, compressing the fitting, the tube and the receiving fitting to secure the vessel inside.

Standard compression fittings are convenient and used in quick field installations since they don’t require tools to assemble. These fittings, usually made of brass, are appropriate for aluminum, copper and plastic tubes.

Push-to-Connect Fittings

Similar in mechanism to compression fittings, push to connect fittings use an O-ring instead of metal ferrule used by compression fittings. The O-ring is made from vulcanized rubber that regains its original form after being released—allowing the fitting to get undone as easily as they were assembled. Push-to-connect fittings are commonly used in lower pressure applications.

Since push-to-connect fittings are easily disconnected and reconnected, this makes them ideal for applications that require frequent alterations. Moreover, these fitting can be utilized with steel, brass, copper, polyurethane, nylon, etc.

Quick Connect Couplings

Quick connect coupling are widely used in applications that require connections that direct the flow of water, air or gas. Also referred to as quick release or quick disconnect coupling, quick connect couplings make a seamless connection for fluid transfer.

Usually operated manually, these fittings are a great alternative to flanged or threaded connections.

Check valves

Simply put, check valves permit the flow in a single direction in pneumatic systems. This prevents the possibility of a reverse flow. Since check valves are self-automated, they work consistently even when the manufacturing facility falls short of manual assistance, air or electricity.

Apart from manufacturing plants, check valves can even be found in homes—sump pumps usually have check valves over the discharge lines.
