I use rubber stoppers and I think they are the best thing you can
use. They make a very tight system but in the unlikely event of a
pressure build up the stoppers will pop. A #3 or #4 stopper will fit
the 2L bottles. I use a copper tube through the stopper but if you
are paranoid about using copper you could use a glass tube. You can
find small copper or brass tubes at a hobby shop.
