PEX-AL-PEX differentiates itself from standard PEX with its Aluminum core. This allows it to expand less at high temperatures and hold its shape better than regular PEX.

PEX-AL-PEX, also called Aluminum PEX, is a 3-layer oxygen barrier PEX tubing. This tubing has an aluminum core that holds its shape when bent so you don't have to tie it down every few feet like traditional PEX tubing. PEX-AL-PEX has the same temperature/pressure ratings as regular PEX, however it is better suited for high temperature applications, such as baseboard and fan coils because the aluminum core allows the tubing to maintain its shape. PEX-AL-PEX also has a lower linear expansion rate, which means that it expands less than regular PEX or copper as it heats up.
