Rubber stopper too big

[Bethany Lynch]

The rubber stopper I have for my 5 gallon plastic bottle is too big. Has anyone tried to cut down or modify?

Seems like it would be very difficult to accomplish. I would find another option for the mean time and get the right size stopper.

It seems to me it would be too difficult. I would find another way to seal the top for the mean time and get the right size stopper. Maybe plastic wrap or aluminum foil.

As kh54s10 said (twice), your best bet would be to get the right size. They come in a slew of sizes.

If you do need to cut it down before you can get to the homebrew shop, I would suggest using a razor knife with anew blade. It's going to be nearly impossible to get it perfectly round though.

Thank you. The woes of ordering things online.

Foil will do, just sanitize it first. Same with a Ziploc bag and rubber band.
