[SEL] OT - what is NPT REALLY..........

[Bill Dickerson]

Need word from experts - not "opinions" so I can avoid a pissing match with
someone.

NPT - I've been told national pipe thread.
I'm BEING told, no, it's national pipe taper

I showed a fellow a site by Kohler, the plumbing fixture folks, that states
national pipe thread, he came backwith an engineers toolbox site that says
national pipe taper.

If I'm wrong, I want to know so I can go back and tell him he's
right.........
