Thank you all for the interest and information on my Query. I just got notification from my customer. The NTP is, as I suspected, a typo and should have been NPT.
Thanks again.
Dear 19488
I am well aware of the entire series of NPT, NPTR, NPSC, NPSM, NPSL, NPSH, NPTF, PTF-SAE SHORT, NPSF, and NPSI. However, I am looking for any reference to NTP. Pardon my ignorance, but what is Francophone?
Thanks.
I have a customer who is requiring NTP pipe threads. Specifically NTP3/4-14 and also NTP3/8-18. I suspect a typographical error so I checked Machinery's Handbook, 25 Edition and lo and behold, on page 1778, there is mentioned an NTPF thread. However, I suspect this is another typo??
Has anyone...
