Air Fittings 101

If you are new to the mechanic world, just learning a new area of mechanics, or have a project ahead of you that deal with air fittings, you've come to the right place. Air fittings have various ues and applications, and hopefully, this guide will help you become more familiar with them.


MST-SCR's tech blog tells us that air fittings are standardized parts of a piping system that are used for attaching sections of pipe together. Much like an elbow, cross, or coupling, air fittings are an essential part of any pipe system that uses air compression.

The biggest thing when finding the right air fitting for your mechanical job is looking for the right size. The size difference is the most obvious physical difference that you can see. It is very important to have the right size fitting. For example, having a leak in a compressed-air system can cost a lot of money. $1,200 a year can be wasted when a 100 psi system has a 1/8 inch diameter hole. If you don't have the right size air fitting, it can cause leaks and cost hundreds of dollars. 

Air fittings can be used in many unique systems. Special air fittings can be made to be used with polyurethane tubing, conventional nylon, or soft nylon, for example. This means that they can be designed to work with many different kinds of materials. This is true for different pressure systems as well. High-speed operations, vacuums, or applications that are copper-free are all different situations that special air fittings can be used for.

When you want to use an air fitting, making sure the fittings are in good shape is a necessary part of keeping the equipment in its optimal working condition. The fittings should maintain a constant flow of air and pressure within the system so the performance of the air tools is not compromised. An air compressor will not output the correct amount of pressure to get the job done if the fitting is not allowing the proper air flow. 

If you are working with air fittings for the first time, this guide can help you better understand what you're getting yourself into.
