This category contains PEX-Aluminum-PEX (PEX-AL-PEX) tubing manufactured by Rifeng. Tubing is available in several sizes and lengths.
FostaPEX tubing adds aluminum and PE outer layers to the tubing to provide form stability and an oxygen barrier. FostaPEX can be bent and will hold its new shape - excellent for exposed runs in basements and baseboard connections. For use with the Viega press fittings only.
Multicor PEX-al-PEX is a multi-layered composite tubing consisting of an interior aluminum tubing lined with inner and outer layers of PEX. Multicor PEX-al-PEX offers 100% Oxygen diffusion and can be embedded in concrete or installed in wall, floors, and ceilings. The aluminum layer in the PEX-al-PEX is what creates the oxygen barrier. Perhaps the best quality of PEX-al-PEX Tubing is its thermal memory. Once the tubing is shaped a certain way, it will hold that shape. Multicor PEX-al-PEX PEX Pipe meets ASTM 1281 and is certified by the NSF. It is rated by the PPI : 200°F at 100 psi, 180°F at 125 psi, and 73.4°F at 200 psi.
Includes chamfering tools and the Fostapex prep tool. The chamfering tools prepare Multicor and other PEX-al-PEX Tubing for making connections, as well as clean the inside of the tubing and re-round it for easier connections. The Fostapex prep tool peels the outer PE and aluminum layers from the FostaPEX tubing, allowing it to be compatible with the standard Viega PureFlow PEX Press system.
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.
