Need thread pitch / spec / dimensions...

[mike100]

I think it is 3/4" and the thread pitch is 14NC. I just repaired an air tube fitting and i got a bushing with the same external thread.

Interesting to note that many of the small block applications one-way air injection check valves are one size smaller.
The 63-504 fit on my repair: http://www.downwindmarine.com/Pipe-R...-90891187.html (note dimensions are for inside diameter and threads- the outside is 3/4's)
