Prismatic Option
If your just looking to use the threads from the STL then model the part in Fusion, then change it to a mesh, then use the combine command to unite the two meshes.

Sorry I didn't take the time to look into the STL file, but now that I have I see why my suggestion might not work. I tried repairing the mesh as there are some nonmanifold surfaces and the result looks to already degenerated to the point where the threads would no longer work. All the Mesh to Brep conversions I have done threads have never remained useable after the conversion. The solver is not to the point where it can interpret the spiral and maintain it, even my experience with Geomagic a software meant specifically for this type of application it would be very labor intensive to create all the face groups and specification to have this work. You are much better off remodeling the part. Here is a shot of just the repaired surface no conversion.

I'm trying to do a prismatic solve on only the outer threaded section using a plane cut on the mesh body. But I was thinking if this is a standard fitting or coupler would you be able to find a step file on McMaster-Carr or similar sites?

Attached is a 1/2 to 1/4 NPT adaptor I found on McMaster-Carr that seems to be the same thread, the thread in the STL is not modelled correctly anyway. Maybe you can modify this part.
