I dont know if this will help, but give it a shot!

(they make couplings for this sort of endeavor)

go to the bottom of their website and download their catalog..in PDF format..(requires adobe acrobat reader to view..its free from adobes website as well)

page 4 will show the realative outside diameters of no-hub, extra-heavy cast-iron, and Duriron.

I have run into duriron twice in commercial buildings and it was NO FUN!
almost broke my chain snappers! I had to cut it with an “emergency saw” with carbide wheel!
the only thing I saw in their PDF catolog that had a combined wall thickness of 3/4″ was DURIRON, but they only list this up to 4″ inside diameter?????
5″ extra heavy cast iron is listed as 5-1/2″ outside diameter.

Wait till SYLVAN is back on this bulletin board…
He may be able to help you/(us) out!
