Manabloc PEX A port adapter?

[thetoolsmith]

I'm installing a Kohler 3 port digital shower valve system and they recommend 1/2 copper or 3/4 PEX supply lines (I'm assuming this is PEX B) With my Manabloc manifold I can only find 1/2 and 3/8 port adapters for PEX B. Does anyone know where I can find a 1/2 expansion type port adapter for this manifold? I think 1/2 Uponor PEX will get me a lot closer to the volume needed for 1/2 copper supply lines?

Thanks,
-Paul

Just got an email response back from Manabloc Tech Support:

Paul,

Unfortunately we do not offer a 3/4" port adapter for the ManaBloc and in most cases when a 3/4" line is required the installer will connect two 1/2" ports together with a 1/2" 90° elbow and a 3/4x1/2x1/2 tee running the 3/4 portion of the tee to the fixture.

Sounds like this is the solution
