I've never installed a shower valve, and the instructions are laughable. However, it is a new Moen with female threads for each supply and output. As opposed to brass fittings with male threads, you cannot directly solder to the valve as an alternative. As a secondary question, I read to both do and don't use teflon on the threads. I always have in the past, even with some compression fittings, and I would normally use teflon for these connections.
So I figured I have a few options. I'm running PEX as my supply, but I planned on sweating copper to the shower head for rigidity.
1) Sweat male threads onto copper stubs, let cool, install into the shower valve body before installing into wall. I just need to lay everything out ahead of time near the valve.
2) go all PEX and get male threaded PEX adapters. Insert the PEX fitting into the valve, install valve, then come back and install the supply lines.
If someone could suggest an alternate method as well, I would appreciate it.
As a side note, the only way I've seen this installed in an all copper setup is to install male-male fittings in each valve supply, then sweat on male thread fittings on the copper supply lines. The connection is then made by a flexible, rubber supply line like for a faucet. Otherwise, I'm confused how a remodel or other all copper install would even work due to the teflon issue.
