Mixing Pex types

Kind of an odd question maybe.

Is there anything wrong with using Pex A with clamp type connectors that are typically used with Pex B?

My reasoning is where we work we already have the tools, rings and fittings for the clamp type, but I hate trying to straighten Pex B where Pex A generally straightens on it's own.

    Generally speaking pex A will already have the approval for crimp type connections. Specifically Uponor pipe does have this rating listed on the side of the pipe. You will see it labeled somewhere "F1807" So far I have not found a pex that does not have that F1807 number as an approved fitting method.

    One thing to note is that the pex manufacturer may offer a different warranty when using their system complete, I am not sure how firm that is as it has never come up for me

    You can also get 20’ straight lengths for short straight runs.
