PEX-AL-PEX Vs PEX
Some of these features include; Structural differences: The PEX-AL-PEX has an aluminum layer that is bonded to both the inner and outer layer of the pipe. PEX on the other hand, is a plain extruded pipe that has no coatings or any additional layers.
Will PEX hold air pressure?
Unfortunately, PEX plumbing systems are pressure rated at as much as 60% lower than a FlowGuard Gold plumbing system. With a maximum pressure rating of 160psi, it is entirely possible for system pressures in a multifamily or commercial building to exceed the rated pressure for a PEX system.

What do the numbers on PEX pipe mean?
A 1 indicates that the tubing meets the requirements for exposure for one month, 2 corresponds to a three months exposure rating and 3 indicates a six months exposure rating. The hydrostatic design stress (HDS) for water at 73 °F (23 °C) is indicated by the third and fourth digits in the code sequence.
Are there different fittings for PEX A and PEX B?
PEX A uses an expansion-style fitting. These fittings are much larger in diameter the PEX B fittings, and require an expansion tool. Using the expansion tool, you enlarge the pipe and sleeve in order slide in the fitting.

Which is better PEX A or PEX C?
One of the most apparent differences is that PEX A is very flexible and doesn’t show any coil memory. So, as a user, you can repair any kinks simply with a heat gun. On the other PEX C is manufactured via the Electronic irradiation or cold method of cross-linking. PEX C is also more vulnerable to kinks and damage.

must be made of non ferrous metal such as copper, brass or stainless. Because with pex tubing, without the oxygen diffusion barrier, oxygen molecules can pass thru the tubing causing ferrous metals to continue to rust until they fail.
