PEX-to-female-thread adapters were among the plumbing fittings I bought.
The featured Amazon option is EFIELD PEX-to-Female-NPT Adapters.
Both Interfaces on a Plumbing Adapter
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.
The cargo floor during my preparation session before sound deadening.Removing stuck-on residue during the floor cleanup.
My Takeaway for the Build
My interior preparation put water-system openings before the later cabinetry and panels. The female-thread-adapter purchase makes both ends important. The featured EFIELD connects half-inch PEX to three-quarter-inch female NPT; SharkBite changes the connection and thread size, while GRIDTECH changes the thread type to garden hose.

The current EFIELD option combines a half-inch PEX barb and a three-quarter-inch female NPT connection. This page preserves the original purchase separately while showing the current fitting format. When planning a transition to equipment, record the size and connection method at both ends and include access for the tube fastener and threaded joint.
The tubing end and equipment end can have different nominal sizes. Listing only one can lead to the wrong transition fitting.

EFIELD PEX-to-Female-NPT Adapters
Half-inch PEX barb to three-quarter-inch female NPT.
This brass adapter combines a half-inch push connection with half-inch female NPT threads. Its two connection styles transition between a tube and a threaded fitting.
This brass swivel adapter joins half-inch PEX tubing to a three-quarter-inch female garden-hose thread. The rotating hose nut allows the threaded end to turn separately from the barbed body.
