Hi Bud,
Not important enough to argue about since both size plugs will do the
job, but I did have challenge for those who would insist that 1/8-27
NPT is the correct thread. Screw the air injection manifold into a 1/8
pipe coupling and remove it undamaged, and I buy the beer! I wonder if
Larry would share the Guiness with me? Samuel Adams Lager is brewed
in my hometown now, and it would be a fine choice also.

The idea of 7/16-20 came from measuring the mating air manifold. It is
a 7/16-20 UNFstraight thread, it is not a tapered pipe thread. 1/8
pipe is a bit smaller and the pitch is close so a 1/8-27 pipe plug
screws in, that doesn't make it the thread size.

where the idea of 7/16 x 20 came from.
