A half-inch PEX fitting assortment was part of my water-system purchases.
The featured Amazon option is Half-Inch PEX Fitting and Valve Kit.
Where it fits my build
My Day 87 plan put the body openings ahead of the aluminum framing, flooring and wall panels. I specifically included the shower drain and the openings for three water tanks in that order of work.
I removed cargo tie-down hardware to leave mounting points for the extrusion framing, and removed door trim for the later insulation and paneling. SketchUp helped me plan how those separate jobs would fit together.

My build notes
The useful part of this diary entry is the sequence. I wanted to finish the drilling while the interior metal was bare, so later work would not mean opening finished surfaces again.
The photographs show my preceding floor-preparation session. Sweeping, washing and removing residue created the starting point for the interior work I described next.
I planned the openings and mounting access before enclosing the interior.
Alternative products
Two alternatives to compare
The featured kit packages fittings and valves together. SharkBite couplings and SUNGATOR elbows offer an alternative way to buy individual connection types for a planned layout.
SharkBite Brass PEX Couplings
These brass couplings join half-inch PEX tubing in a straight line. Barbed ends enter the tubing on both sides of each fitting.
