Hello everyone. I'm a newbie to the site who was looking for help with a toilet installation. I have a 45 degree offset toilet flange that has the oval shaped opening instead of the 3 or 4 in opening. Is there a certain wax ring to but in order to seal it, or do I have to try and replace it with the latest and greatest? Thanks all!

Wax ring is flexible. Stand it on its side, gently push on it and it will give you oval shape. Put it over the closet ring and set the toilet
