 Compression Fitting To Go From Copper to Pex?
Author: mk7474 (NY)

Hi, I would like to a use a compression fitting on 1/2" copper to transition to 1/2" Pex. What is the best way to do this? This is my newbie best guess:

1/2 x 1/2 mpt brass compression(copper side) -> 1/2 fpt pex brass adapter (pex side)

Teflon tape and/or pipe dope on threaded connection? Thanks!

All you need is a Sharkbite coupling. It already has the "support insert" for PEX and you remove the one on the copper side.
