Pex For Compressed Air: A Guide

If you’re looking for a piping system that is both efficient and reliable, pex for compressed air may be the perfect choice for you. This blog will teach you everything you need to know about pex tubing for compressed air systems.

So, in this guide, we will discuss how to select the right pex tubing, how to install it, and how to maintain it. We’ll also provide some tips on choosing the right compressor for your needs.

But before we get into the topic, let us discuss what is pex and for what purpose people use it.

What is Pex?

Pex is a type of tubing that is made from cross-linked polyethylene. It is often used for plumbing applications, but it can also be used for compressed air systems.

Why Use Pex?

There are several reasons why pex is a popular choice for compressed air systems.

First, pex is durable and can withstand high pressure and temperatures. It also has a low coefficient of friction, which makes it easy to move through fittings. And finally, pex is resistant to corrosion and scale buildup.

Now that you have a basic understanding of Pex, let’s get into the other details of pex for compressed air.

Types of Pex for Compressed Air

Different types of pex.

There are three types of pex that are commonly used for compressed air systems:

1. Smooth Wall Pex Tubing

This type of pex has a smooth inner surface that is less likely to collect dirt and debris. It is also more flexible than other types of pex, which makes it easier to install. However, smooth wall pex is not as strong as rigid pex and is more likely to kink.

2. Rigid Pex Tubing

This type of pex has a corrugated inner surface that gives it added strength. It is less likely to kink than smooth wall pex, but it is more difficult to install. Rigid pex is also not as flexible, which means it may not be suitable for some applications.

3. Coil Pex Tubing

This type of pex is made up of coils that can be easily bent and twisted. It is the most flexible type of pex, but it also has the lowest strength. Coil pex is best suited for applications where flexibility is more important than strength.

How To Install Pex For Compressed Air? Step-By-Step

Installing pex for compressed air can be a bit tricky, so it’s important to follow the steps carefully. Here are the basic steps:

Step Number One:

First, you need to select the right pex tubing for your system. There are several factors to consider when choosing pex tubing, including temperature and pressure ratings, chemical resistance, and bend radius.

Step Number Two:

Once you’ve selected the right tubing, you need to cut it to the correct length. Be sure to leave enough room for fittings and bends.

Step Number Three:

Next, you need to install the pex fittings. There are many different types of fittings available, so be sure to select the right ones for your system.

Step Number Four:

Now it’s time to install the tubing. Start by peeling back the insulation and slipping the tubing over the fitting. Make sure that the tube is fully inserted into the fitting and that there are no kinks in the line.

Step Number Five:

Once the tubing is installed, you need to crimp the fitting. There are several different types of pex crimping tools available, so be sure to select the right one for your system.

Step Number Six:

Finally, you need to test the system for leaks. Be sure to use a leak detector or pressure gauge to test the system before you turn on the compressor.

Now that you know how to install pex for compressed air, let’s discuss how to maintain it.

How To Maintain Pex For Compressed Air? 5 Tips

Pex for compressed air systems is relatively low maintenance. However, there are a few things that you can do to help keep your system running smoothly.

Tip One: Flush The System Regularly

First, be sure to flush the system regularly. This will help remove any built-up corrosion or scale.

Tip Two: Use a Compressor Oil

Second, use a quality compressor oil and change it often. This will help prevent wear and tear on the compressor.

Tip Three: Inspect The Pex Regularly

Third, be sure to inspect the pex regularly for any signs of wear or damage. If you see any damage, be sure to replace the tubing immediately.

Tip Four: Use A Filter

Fourth, use a filter to help keep the air clean and free of contaminants.

Tip Five: Drain The Tank Regularly

Fifth, be sure to drain the tank regularly. This will help prevent corrosion and damage to the compressor.

Now that you know how to select pex tubing, install it, and maintain it, let’s learn about the advantages and disadvantages of pex for compressed air.

Advantages of Using Pex For Compressed Air

There are many advantages to using pex for compressed air.

1. Very Strong & Durable

One of the biggest advantages of pex tubing is its strength and durability. Pex is very strong and can handle high pressures without kinking or bursting.

2. Easy To Modify

Another big advantage of pex is that it’s very easy to modify. You can easily add or remove fittings without having to cut the tubing. This makes it the best choice for you if you are starting your woodworking business since it can be modified according to your workshop’s needs.

3. Easy To Repair

Pex is also very easy to repair if it gets damaged.

4. Corrosion Resistant

Pex is also corrosion-resistant, so it’s ideal for use in harsh environments.

Disadvantages of Using Pex For Compressed Air

There are a few disadvantages to using pex for compressed air.

1. More Expensive

Pex is more expensive than other types of tubing.

2. Not Much Flexible

Pex is not as flexible as some other types of tubing, so it can be difficult to route around obstacles.

3. Can’t Resist Chemicals & Temperatures

Pex can be damaged by high temperatures and chemicals.


So, is pex the right tubing for your compressed air system? That depends on your specific needs and requirements. However, if you’re looking for a strong, durable tubing that’s easy to install and maintain, pex is a good option.
