Hi folks,

Someone asked me to help cut some internal threads for some fittings without the taper. I've no experience with NPT and so I though if you folks can help me out.

For NPT without the taper, would it be like those usual threads on bolts? The pitch I gathered is to be 11.5 tpi (which I'm also not sure if my lathe has the gear combination for).

TIA.
