How To Choose The Right Pneumatic Fitting?

There are several different kinds of pneumatic fittings on the market, and picking the right one isn’t always easy. You need to know the tubing being used or not, the operating air pressure, the thread type on the taking fitting (if any), the amount of vibration the fitting is required to endure, and more.


Here are some of the basic kinds of pneumatic fittings to help you select the right one:

Quick Connect Couplings:

Quick Connect Couplings are essential when it comes to connections that direct the flow of gas, air or water. Also known as a quick disconnect or immediate release couplings, they provide a fast connection for transferring fluids. Usually operated manually, they work as a great alternative to threaded and flanged connections.

Check Valves:

In simple terms, check valves enable the flow in a single direction; hence, preventing chances of backwards flow. Being a self-automated valve, they consistently work even if the manufacturing equipment falls short of electricity, air or manual assistance. Not just production plants, check valves can be seen everywhere, including homes. In case you have a “sump pump”, it must have a check valve fitted above the discharge line. Check valves used in almost every industry that makes use of pumps.

Hi-Duty Flareless Fittings:

This kind of fittings fall into the subcategory of condensation fittings. However, they are specially made applications that include high pressure; usually more than 1000 PSI. So, if you are in the niche manufacturing that has special requirements in terms of High PSI, you should opt for it.

Push-Connect Fittings:

Push-Connect Fittings use a related mechanism as compression fittings. However, instead of utilising a metal ferrule, these fittings utilize an O-ring (formed utilising vulcanised rubber) that holds the ability to get its actual shape to let loose.

As a result, this feature allows the fitting to get easily undone, just the way it was manufactured and constructed. Push-connect fittings have applications that include lesser air pressure. These fittings are very simple to connect, disconnect and then reconnect, perfect for applications that include frequent alterations. Moreover, they can be used with brass, steel, copper, nylon, etc.

Barbed Fittings:

These kinds of pneumatic fittings rely on friction to keep the tube connected. Therefore, they manage to be used for very low-pressure works, as anything higher would break the pipe off of the fitting. Barbed fittings are usually made of either thermoplastic or brass, and are used with polythene or rubber tube.

In addition to these stated pneumatic fittings, there is also a variety of varying benefits, depending on the application. The more different job requirements are, the more atypical the fittings will be.

Generally,  push-connect fittings, compression fitting, Festo Pu Tube Fittings and speciality compression fittings can be quickly bought and utilised for several applications, and you should view your project requirements before selecting the correct pneumatic fitting.

Most of the fittings are available to create pneumatic tubing and hose attachments for connection to mating components. These include barbed, swaged, push-to-connect, crimped and reusable versions; and they come in plastic,  steel, brass, stainless steel and other materials.

First and foremost, designers should assure the fitting and tubing or hose are fit with each other, as not every fitting design is suitable for every kind of tubing or hose. Other essential considerations for fittings include pressure-holding capacity, size, ease of installation and weight, corrosion resistance and, of course, cost.
