What is PEX?
PEX PEX, or cross-linked polyethylene, is a type of plastic tubing used in plumbing and heating systems. Unlike traditional copper pipes, PEX is flexible and can bend around corners and obstacles with ease. It also resists corrosion and scale buildup, making it a popular choice for water supply systems.
PEX can also be used for air lines in certain applications, like pneumatic tools in industrial settings. However, it’s important to note that there are specific types of PEX tubing and fittings designed for air lines, as using the wrong materials could result in leakage or even bursts. When choosing PEX tubing for any application, it’s essential to follow manufacturer guidelines and ensure that the product is certified for its intended use.
With proper installation and maintenance, PEX can provide a reliable and durable piping solution.
What are Air Lines?
Air lines are an essential component of compressed air systems. They are often made of durable materials like PEX, which stands for cross-linked polyethylene. PEX air lines provide an excellent combination of flexibility and durability, and they are known for their resistance to temperature and pressure changes.
One of the main benefits of PEX air lines is their ability to maintain consistent air pressure, which is critical for the performance of air-powered tools. Burstiness, which refers to sudden increases in air pressure, is a common issue in compressed air systems, but PEX air lines help minimize it. Because they are flexible, PEX air lines also make it easier to install and maintain compressed air systems.
Overall, PEX air lines offer an excellent balance of flexibility, durability, and reliability in compressed air systems.
Pros and Cons of Using PEX for Air Lines

On the positive side, PEX is a flexible tubing material that can be easily bent, making it easy to maneuver around obstacles in your workspace. It is also lightweight and doesn’t require the same level of preparation as other piping materials.
However, PEX does have lower pressure ratings than other materials, meaning that it might not be ideal for high-pressure applications. Additionally, PEX is not UV-resistant, meaning it’s not suitable for outdoor use. Overall, using PEX for air lines can be a good and cost-effective option, but it’s important to consider the specific needs and requirements of your workspace before making the decision to use it.
Advantages of PEX
PEX tubing is an increasingly popular option for air lines due to its many advantages. PEX is made from a flexible plastic material that is highly resistant to heat, chemicals, and corrosion, making it ideal for use in tough industrial environments. Some of the pros of using PEX for air lines include its lightweight design, which makes it easy to work with and install, as well as its ability to resist freezing in cold weather.
Additionally, PEX tubing has a high burst pressure, meaning it can handle high-pressure operations without breaking or leaking. However, there are some cons to using PEX for air lines, including the risk of kinking or bending, which can obstruct airflow. Overall, PEX offers many benefits for air line applications, making it a suitable option for many industrial settings.
Disadvantages of PEX
PEX, air lines, pros and cons PEX piping systems have become increasingly popular in different applications due to their affordability, flexibility, and ease of installation. However, like any other material, PEX has its disadvantages that you need to be aware of before considering it as an option for your air lines. One of the main cons of using PEX for air lines is the fact that PEX piping can be susceptible to damage and bursting when exposed to high-pressure conditions.
Therefore, PEX air lines may not be suitable for heavy-duty applications where high-pressure conditions are common. Another disadvantage of PEX is that it may not be able to withstand extreme temperatures making it unsuitable for some applications. Despite these drawbacks, PEX offers several advantages like being corrosion-resistant, lightweight, and having low noise transmission.
In conclusion, whether you should choose PEX for air lines or not relies on the intended use and the specific circumstances.
Considerations for Using PEX as Air Lines
Are you wondering if you can use PEX for air lines? While PEX piping is commonly used for plumbing, it can also be used for compressed air distribution systems. However, it’s important to note that there are certain considerations that need to be taken into account. First and foremost, it’s crucial to select the right type and size of PEX tubing for your specific application.
Additionally, it’s essential to ensure that the PEX tubing is installed properly, using appropriate fittings and supports, and that it is adequately protected from potential impacts or abrasions. Another important factor to consider is the likelihood of moisture accumulation within the PEX tubing, which can lead to corrosion and potential damage. To prevent this, it’s recommended to use moisture traps and drain valves in the system.
Overall, while it is possible to use PEX for air lines, it’s important to carefully evaluate the specific requirements of your system and seek guidance from a qualified professional to ensure safe and effective installation.
PEX Tubing Size
When considering using PEX tubing as air lines, it’s important to take into account the size of the tubing. For most residential and light commercial applications, 1/2″ PEX tubing is sufficient for air lines. However, if you’re using compressed air for heavy-duty industrial applications, it may be necessary to use larger tubing sizes.
It’s also important to consider the distance and amount of bends in the air line, as these factors can affect the pressure and flow rate of the air being delivered. When in doubt, it’s always best to consult with a professional to ensure that you’re using the correct size and type of tubing for your specific application needs. By taking the time to consider all of these factors, you can ensure that your PEX tubing air lines will function smoothly and efficiently.
PEX Tubing Pressure Rating
When it comes to using PEX tubing as air lines for your compressed air system, it’s important to consider the tubing’s pressure rating. Unlike water, compressed air puts a lot more stress on the tubing due to its highly pressurized state. PEX tubing is known for its flexibility, durability, and resistance to corrosion, making it a popular choice for air lines.
However, not all PEX tubing is rated for high pressure applications. It’s essential to choose PEX tubing with a high enough pressure rating to ensure it can withstand the pressure of your compressed air system. Failure to do so could result in leaks or even burst tubing, which can lead to costly and dangerous situations.
Therefore, always check the pressure rating of your PEX tubing before using it for your compressed air system.
PEX Tubing Temperature Rating
PEX tubing temperature rating When it comes to using PEX tubing as air lines, it’s important to consider the temperature rating of the tubing. PEX tubing is typically rated for use in plumbing applications with temperatures up to 200 degrees Fahrenheit. However, air compressor systems can produce much higher temperatures, which could potentially cause PEX tubing to fail if it exceeds the recommended temperature limit.
It’s important to ensure that the tubing you select is rated for the maximum temperature you plan to use it in. Additionally, PEX tubing can be susceptible to bursting, especially if it’s exposed to freezing temperatures or high pressure. To prevent this, it’s important to install appropriate valves and pressure regulators to manage the air pressure in the system.
By taking these considerations into account, PEX tubing can be a reliable and cost-effective option for air compressor systems.
Conclusion
After much deliberation and consideration, the answer to the question “Can you use PEX for air lines?” is…
it depends! While PEX tubing is great for plumbing applications due to its flexibility and durability, it may not be the best choice for high-pressure air systems. However, for DIY or low-pressure applications, PEX may work just fine. So, much like life, the answer to this question is not a simple yes or no, but rather a nuanced and contextual response.
Keep that in mind next time you’re considering using PEX for air lines, and as always, be safe and thoughtful in your decision-making. “
