Thread Identification
(OP)
I am trying to identify the external thread on an EGR fitting in the manifold of a 1999 Ford Expedition. The major diameter of the thread is 1.053 with 13 TPI. The only thread I have been able to find with 13 TPI is a standard 1/2-13.
Any enlightenment would be greatly appreciated.

3/4 NSP has a major of 1.034 to 1.024 but with 14 tpi, perhaps your thread count is off by one?
