A very short stub of PVC into a PVC female adapter.
The hub on that box won't take a threaded fitting anyway, you appear to have a 3/4 inch hub that was meant to cement a 3/4 PVC conduit into.
May or may not be listed for the purpose but some 1/2 inch female adapters will perfectly fit those 3/4 hubs and looks pretty slick when installing that way. Again may not be listed for such purpose but works great.
Reducing bushing that is threaded inside may not be easy to find - one that is listed for the application anyway.
I agreePretty sure iwire sail all that needed to be said on this subject. Looking for a reducing bushing with inside threads is simply ridiculous.

How does affixing the cover secure the box:?You just have to Safely Connect an Electrical Outlet, These boxes are used for straight line conduit runs and splices. To secure the box once you have placed your wiring, simply affix a single gang electrical device cover onto it.
