Pressure resistance of PFA Tubes

Pressure resistance PFA Tubes

In industrial applications where chemical resistance and reliability are essential, PFA tubes play a crucial role. These flexible pipes are designed to withstand a wide range of chemicals and offer durable performance under various conditions. One of the most important factors to consider when choosing the right PFA tube for your application is pressure resistance, particularly working pressure and burst pressure. Let us elaborate on these aspects and understand how they affect the performance of PFA tubing.

Working Pressure of PFA Tubes:

The working pressure of a PFA tube refers to the maximum pressure the hose can withstand during normal use without damage or failure. Generally, the burst pressure is divided by 3 or 5 to determine the maximum working pressure. In this way, there is an ample margin of safety built in. Of course, we recommend extensive testing as conditions, temperature and risks vary from application to application.

This parameter is often expressed in bar or psi (pounds per square inch) and is critical to ensuring safe and reliable operation of the piping system. When selecting a PFA tube, it is essential to know the desired working pressure and ensure that it is sufficient for the specific pressure requirements of your application. As shown below, the thicker the wall of the hose the higher the burst and working pressure.

Burst Pressure of PFA Tubing:

The burst pressure of a PFA tube is the maximum pressure to which the hose can be subjected before catastrophic failure, which can lead to cracks, ruptures or leaks. This value is typically 3 – 5 times higher than the working pressure to provide an additional safety margin for unforeseen peak loads or pressure surges in the system.

Optimal Performance and Safety:

Understanding the working pressure and burst pressure of PFA hoses is vital to ensure optimal performance and safety in industrial environments. By considering factors such as the nature of the media being transferred, operational conditions and the safety margins required, you can make an informed decision when selecting the right PFA tubing for your specific needs.


PFA transparent tubes offer excellent chemical resistance and reliability for a wide range of industrial applications. When choosing the right tube, it is essential to consider the working pressure and burst pressure to ensure optimal performance and safety. By understanding and paying close attention to these important factors, you can rely on a piping system that meets your needs and provides the highest standards of quality and reliability.
