GHT relies on a gasket to seal, not a tight fit between the threads. This makes it more resistant to dirt and also cheaper to manufacture. I would guess that your sizes will work fine and you shouldn't be concerned.
From the sizes you measured, the radial clearance is only .0105 (ten thou.) That might be a little loose for precision threads, but anything smaller than about 2 thou clearance becomes very difficult to assemble.
All that said, the Machinery's Handbook has information on hose threads and gives some tolerances. It's on page 1873 (at least in the 28th edition.) Depending on the material and processes, they list a minimum major diameter for the male thread as low as 1.035. This website also lists the appropriate dimensional information in case you don't have the handbook. The official standard is ANSI/ASME B1.20.7. If you are specifying compatible threads for a production run, you should probably consider buying it or at least referencing it on your drawing.
On another type of thread, like NPTF where the threads are the sealing component, tolerances will be tighter. Fittings that have a tapered or flared metal-to-metal surface to seal usually have thread tolerances somewhere in the middle of these two.
