Cutting Taps Pipe Threads Standard (Screw Threads, Center Holes)

Is the external parallel pipe threads "G" the same as "PF"? What dies should I use? Can I produce the external parallel pipe threads with the solid dies "D PF"?

The external parallel pipe threads "G" is basically the same as "PF". The symbol of the threads has been changed from "PF" to "G". You can use YAMAWA "D PF" for both of the external parallel pipe threads, "PF" and "G".
