No, Bluefin does not have 3/4" loop fitting options.
No, unfortunately the manufacturer does not offer the appropriate pex press loop fittings to make it compatible with Fostapex tubing.
Yes, it can.
1/2" PEX has a .475" inside diameter and a 5/8" outside diameter. It sounds like you have 1/2" PEX. The outside diameter of PEX will always be 1/8" larger than its nominal size.
This manifold works with Uponor PEX tubing, but there are no ProPEX fittings available for use with it. Additionally, the loops on this manifold must be either 1/2", 3/8", or 5/8". To connect 3/4" ProPEX to the shutoff valves (which have 1" female standard pipe thread), you can use the part LF4527510 ProPEX fitting.
As long as the Rehau tubing is standard 1/2" PEX and not PEX-AL-PEX, you can use the MA-50P fittings. You can use the MP182 pressure gauge with this manifold.
You can install the manifold upside down. Just keep in mind that you won't be able to read the visual flow meters if they are upside down.
I turned mine upside down and actually had to take it apart because I needed the flow from the opposite side too. Yes it does work but make sure your soldered fittings that connect to it are all lined up or it may leak like mine did. The flow meters won't work upside down but evidently Mr. Pex flowmeters (item # at pexsupply is 3710172)do work upside down. I plan to order some for my system. Also, the actuators will end up upside down and there is the possibility of water getting in them. I had one die after 3 months; I think because it got a couple drips of water in it.
You need to use MA-50P fittings with 1/2" PEX at the loops of this manifold.
Yes, it will.
The -50PK version also includes 8 loop fitting assemblies (part MA-50P).
