Thanks for your help Bob; you set me on the right path. I understand a lot better now.

The bottom line is, if the tube and the fittings has the correct listings they can and often are used interchangeably.

Dig into the tech sheets at any tube manufacturers website, Rehau, Uponor, etc and they have documants accepting other brands of fittings and rings if the carry the correct ASTM listing numbers.

Of course manufacturers prefer you use their components.

I was not aware you could just strip any and all pex-al-pex and use regular crimp fittings and rings. Fostapex, yes, but I wouldn't put them in the same class as the ID is larger on standard PAP. Fostapex and pex-al-pex are not the same thing. @STEAM DOCTOR @Charlie from wmass can either of you clarify this?

Charlie from wmass · May 2019

The only PEX-Al-PEX stocked in my area is Fostapex.

@Charlie from wmass Fostapex is some great tubing. And of course you must use this very helpful tool to peel the PE and aluminum outer coating.
The pipe and tools used for installation are excellent inventions.

@Intplm. I use it often and it has always met my needs. I am using Uponor more for potable water systems though.

Some near the shore line are using fostapex for there water piping as a strong deterrent to flood damage.

I don't know if this was answered or not. Can you use Viega PureFlow press connectors on PEX-AL-PEX?

If you use a proper chamfer tool to pull the out layer off

Grallert · September 5

viega pex jaws work on all the above fittings. heat and water. If you're using PAP you must remove the outer two layers with the correct size stripping tool exposing the inner layer of pex.
