Why, I don't know, but I'm off to get up there in the AM here.

Where's Jerry here? Know the thread dimensions???
In that image the threads are 1/2" - NPT which when measured externally is a dimension something near .830 or so. !/2" NPT is 14 TPI as is 3/4 NPT but 3/4NPT is a dimension greater than 1" when measured externally. NPT is based on the internal diameter of the pipe. The bushings that "mike100" references to are NPT also and the reference to a 14NC is not correct, it's 14 but it's NPT. The image is that of a later manifold but I believe the AIR check valves are the same all years.

1/2" NPT 14 TPI
