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

A Straight Transition in the Plumbing Plan
I used SketchUp to plan the interior and put body openings ahead of the framing, floor and wall panels.
My Interior Preparation notes included the shower drain and openings for three water tanks in that preparation sequence.
I removed cargo tie-down hardware for later framing mounts and door trim for the later insulation and paneling.

My Takeaway for the Build
Planning the water openings early meant thinking through the connection on each side of a fitting. This Spears purchase joins a hose barb to male NPT. The spigot option changes the joining end, while the elbow changes direction; those differences determine which part of the route each fitting serves.

1½-inch insert barb × male NPT
The 1436 adapter provides a straight transition between a barbed hose connection and a male pipe thread. Spears’ insert-fitting catalog separates it from the plain spigot and barbed elbow forms. That distinction is useful when assembling a camper-van plumbing parts list: the hose end, threaded receiving fitting and joining method need to match the route being planned. A nominal one-and-a-half-inch size does not make those different end styles interchangeable. The manufacturer catalog provides the connection reference, while my original purchased adapter and the two existing alternatives remain in their current positions.
This adapter has a male NPT threaded end. The spigot adapter has a plain IPS spigot end.

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.
This PVC adapter joins a one-and-a-half-inch hose barb to a spigot end. The straight fitting connects a hose route to a matching PVC socket arrangement.
