The item in my kit

I bought Spears One-and-a-Half-Inch Barb-to-Male-NPT Adapter as part of my camper van equipment.

I bought this Spears adapter with my water fittings. The transition between hoses and fixed plumbing belongs to the routing decisions that follow the tank-opening plan in my diary.

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 spigot adapter changes the pipe-side connection from threads to a smooth joining end. The elbow alternative turns the route through ninety degrees, changing the space occupied by the connected hose.
