It is essential to ensure that the operating pressure of the air compressor and the pneumatic tools does not exceed the recommended pressure limit for the specific Pex tubing being utilized.

Temperature Range

Pex tubing is designed to withstand a specific temperature range. Extreme temperatures can affect the flexibility and strength of the tubing, potentially leading to cracks or leaks.

It is crucial to verify that the operating temperature of the air system falls within the recommended range for the Pex tubing.

Air Quality

The quality of the air circulating through the Pex air lines is a significant consideration.

Contaminants such as oil, moisture, and debris can have adverse effects on Pex tubing, leading to degradation and potential failure. Proper filtration and maintenance of the air supply are vital to ensure the longevity of the Pex air lines.

Comparing Pex With Other Materials For Air Lines

When it comes to air lines, choosing the right material is crucial for the safety and efficiency of your system. Pex, known for its flexibility and durability, has been gaining popularity as an alternative to traditional materials.

In this section, we’ll compare Pex with other materials commonly used for air lines, including copper, galvanized steel, and polyethylene.


Copper has long been the go-to material for air lines due to its excellent corrosion resistance and high thermal conductivity. However, copper is relatively expensive and requires skilled labor for installation.

Galvanized Steel

Galvanized steel is a robust choice for air lines, offering high durability and strength. However, it is susceptible to corrosion over time, especially in humid or corrosive environments, which can lead to air leaks and system inefficiencies.


Polyethylene, like Pex, is a versatile and cost-effective option for air lines. Polyethylene is lightweight, easy to install, and resistant to corrosion. However, it is not as flexible as Pex and may require additional fittings for complex installations.
