I am in a similar situation, and dont want to thread jack, but what resolution ever came of this?
I have 2 acrylic sumps flat together, 2 perfect holes in each, with 1" bulkheads, and they leaked the first time i put water in to test :/
I did not have a gasket on the threaded side (yet) and used silicone in between the 2 sumps. which obviously failed.
This thread is one of the only ones I could find that had the same concept. Just trying to find a solution.

thanks!

Did you try putting the gasket between the sumps rather than under the flange (or an additional gasket between the sumps)?

Threaded bulkhead on one side, uniseal on the other. Cut a 6" riser in half, threads go into the bulkhead side, cut side into the uniseal.

I didn't go this direction. Figured it was asking for trouble later
