Here's what I used on my Pex lines (1/2 inch) when I installed a new outside shower. If you notice, this photo shows two kinds of connections, the crimped connections and the type that slide on and then the outer ring tightens down. The only thing with the screw on type is, if you over tighten them, you break the plastic seal ring on the inside and then they are worthless. So they absolutely cannot be tightened with tools. Hand tighten only. They are easy to install, work well, and you can pick them up, very easily at your local RV dealership parts store. That's were I got the 2 Pex lines in the photo below and the cut off valves. In the second photo, that's a "T" I connected when I cut the water line to the toilet to install a bidet. Neither of these in the phots have leaked.
