Threaded hole? That would make things far too easy.

I found a couple pictures of this thing...
The filter spout seal is what's stuck. It's a little aluminum piece, much like the gold object shown in these pictures.





As some have suggested, it wouldn't normally be necessary to remove the old one, but I scuffed it up a lot in the process of taking the filter out, (because the filter spout broke off in it upon removal). I got the filter spout left-overs out, so now I just have to get the seal out. This thing is in TIGHT. I might try some different pliers for hopefully sticking up in there and twisting out.

When all is done, I really hope there's no chipped metal particles from this hassle that end up causing trouble
