Good day:

I have a vendor drawing that calls out a 2-1/2-14 UNF SAE-32 Straight Thread O-Ring port. There is a part identified for this port. I inquired the company and was replied with a terse, "That part is obsolete."

What are SAE threads and how do they differ from ANSI threads?

TIA

It is a tube thread for tube size 32 (ID 2 inch, I suppose ). If you find Mil spec MS16142 you will find that standard port thread for that size is 2-1/2-12 UN-2B. It seems that the port thread is a little bit truncated so the outher thread on a pipe can be shallower leaving enough wall thickness.
