PEX-AL-PEX is a special type of PEX tubing that has an aluminum layer sandwiched between the inner and outer layers. The aluminum helps to maintain the shape of the pipe after it has been bent.

This feature makes it easy to bend in tight turns without the tubing springing back. Additionally, this tubing is much more resistant to burst pressures than standard PEX.


PEX al pex is a flexible type of tubing that is often used for hydronic radiant heating, plumbing and in ice melting systems. It is available in many different sizes and coil lengths and has higher pressure ratings than regular pex.

For example, it can withstand a pressure rate of 160psi at 73 degrees Fahrenheit and 79psi at 200 degrees Fahrenheit. It is also resistant to corrosion.

Another advantage of this kind of PEX is that it is able to retain its shape even when you bend it. This can save you from tying it down every few feet.

There are three main types of PEX tubing, each with its own unique benefits. The most common, PEX-A, is a peroxide-based product that provides excellent flexibility and can withstand freezing water temperatures without cracking or leaks. It is the most popular choice among homeowners and contractors for home water-supply plumbing.


Pex al pex is a type of cross-linked polyethylene pipe that has an aluminum lining between the inner and outer layers. The lining helps prevent oxygen from entering the pipe and can improve its overall performance.

The aluminum lining also makes this tube more rigid, which can help you bend it around sharp corners without worrying about it breaking. This tubing is mainly used in radiant heating applications and other high-temperature systems.

It can withstand high temperatures and pressures and is resistant to corrosion and other chemicals. However, it is susceptible to freezing and can burst if water freezes inside of it.

Corrosion Resistance

Pex al pex is a type of plastic piping used for plumbing and pressure services on compressed gas and compressed air systems. It is made of two layers of polyethylene (PEX) and an aluminum (AL) layer.

The layered structure of pex al pex takes advantage of the chemical and corrosion resistance of PEX and the pressure capability of metal. It is a great choice for many types of home and commercial projects.

However, it is important to choose the right kind of pex al pex tubing for your project. Choosing the wrong one can cause problems down the road, such as corrosion and pinhole leaks.

There are several different kinds of pex al pex, including barrier and non-barrier PEX. Barrier PEX is a type of PEX that prevents oxygen from getting into the system, which may be an issue for heating applications.

Energy Efficiency

Energy Efficiency

The lower thermal conductivity of PEX pipes helps keep hot water warm longer, reducing electricity and water costs. Copper, on the other hand, is a conductor that loses heat as it travels through the water.

In addition, PEX piping requires less cutting and fittings than copper. This makes installation faster and cheaper, too.

Using PEX for Radiant Heating Systems

PEX tubing is becoming increasingly popular as a replacement for copper in radiant heating systems. It’s a good choice because it can be bent and curved around corners without springback, eliminating elbow connections that create friction.

Other applications that can benefit from PEX include outdoor radiant heat, warm board systems, and high-temperature radiators. These installations can reduce the number of piping and fittings needed, improve water velocity, and save time by delivering hot water instantly.
