I used male-thread PVC adapters at junction-box entries along the roof route. They connected the straight pipe and fitting layout to the openings I prepared in the boxes.
The route used pipe sections between several boxes. Threaded adapters were part of changing from those pipe sections to the box entries.
The FangKingNo three-quarter-inch male adapters were listed with the roof-wiring materials. Their role was separate from the cable glands used for individual wire entries.
Connecting the Pipe Route to the Box Entries
I drilled the box openings and fitted male-thread PVC connectors and cable glands.
At the passenger-front box I threaded female PVC connectors onto the male parts as nuts.
I cut and connected the adjoining pipe, recording cement at pipe joints and clear sealant at threaded box entries.

My Takeaway from This Job
The adapters marked the transition between the pipe layout and each box. Drilling the entry, fitting the connector and measuring the next pipe section belonged together because the position of one part affected the next.
The box opening and the next pipe section had to be laid out together.

Function
Changes connection style
The adapter joins a socket-style pipe connection to a threaded connection. Those two ends need separate descriptions in a parts list, even when the nominal fitting size looks the same. For a van conduit mock-up, lay out the adapter with the adjoining fitting and pipe before cutting the straight section. Record the overall assembled length and where the threaded joint sits. Keeping the male adapter separate from the female version makes the fitting inventory easier to follow.
The socket and threaded ends join in different ways. Naming both avoids treating a male and female adapter as the same fitting.

Two Alternatives to Compare
The Charlotte fitting is a white socket-to-male-thread PVC adapter. The Cantex fitting is a gray conduit terminal adapter with the same basic socket-to-thread transition. Their body shapes and intended pipe systems distinguish these two approaches to a threaded box entry.
