Hey everyone it's Mark from PexSupply.com and this is Rifeng PEX-AL-PEX Tubing. This PEX-AL-PEX, or PEX-Aluminum-PEX, is a multi-layered composite tubing consisting of an interior aluminum tubing lined with inner and outer layers of Rifeng PEX-b tubing.

It is designed for use in closed-loop hydronic heating systems. The thin layer of aluminum in PEX-AL-PEX tubing acts as an oxygen barrier, preventing oxygen in the air from penetrating the system and rusting cast iron system components.

The aluminum also allows the tubing to hold its shape so that it is more rigid.

It comes in sizes of ½", 5/8", ¾", and 1". PEX-AL-PEX has a larger inside diameter than standard PEX as well as a lower expansion rate.

Rifeng PEX-AL-PEX tubing works with Rifeng PEX-AL-PEX compression fitting assemblies, as well as Multipress (MLC) PEX-AL-PEX fittings. Fittings designed to work with standard PEX tubing will not work with Rifeng PEX-AL-PEX.  

A chamfering tool is required to prepare PEX-AL-PEX prior to making a fitting connection. The tool creates a beveled edge on the inside of the tubing so that the O-ring sets properly. Rifeng PEX-AL-PEX works with both the chamfering tools made by both Mr. PEX and Uponor.

This tubing has a maximum temperature rating of 180 degrees Fahrenheit up to a pressure of 125 psi. It can handle a maximum pressure of 200 psi up to a temperature of 73.4 degrees Fahrenheit. Rifeng PEX-AL-PEX is backed by a 25-year manufacturer's warranty.
