The process of making a home made part and then getting it listed for a one time application can definitely be cost prohibitive compared to using something mass produced that is already listed.

Exactly! I know that it is common practice to thread NPSM fittings into NPT hubs; it's done often and I see it all the time...but it's not an approved method for ground continuity. That's why in my original post, I was asking for suggestions for an "...approved way..."
I wasn't being stingy, I purchased the original t-type bodies thinking that there MUST BE some manufacturer out there making adapters. I bought before I researched it, and I'm really surprised that no one has a product to convert hubs. No biggie...even if I can't sell the screw-type hub versions, I'm still not out that much.

Did you test fit a 1" rigid coupling in the 1 1/4 hub to see how close it fits? I've never tried it with rigid but we used to do something similar with PVC. Or you could be a tap and thread the hubs yourself.

Actually, I did test a 1" rigid coupling last week and it fitted perfectly. I was able to cancel my order for the threaded bodies. So I am using a 1" rigid coupling, a 1" to 3/4" bushing, and a 3/4" compression fitting. The setup isn't really approved for ground continuity, but the inspector is okay with it.
