Actually, all that proves is that the new flange has the correct thread
(same as the old one).  This wouldn't be the first time that some off-shore
manufacturer has used a metric "approximation" that wasn't good enough and
the flange was undoubtedly made on a different machine.  If it didn't come
assembled, then it's a safe bet that it has never been assembled.

Definitely worth a try.  Something that might help is to clean the area in
question, and then rub black magic marker on it (or machinist's dye if you
have some).  Then try to spin the flange onto it.  You should see a bright
spot where it is binding.
