I am going to be drilling out an opening for my 10 gal mash tun/cooler I plan on drilling a 7/8th inch diameter opening. Now instead of making a valve I am just going to use a predrilled stopper ( I also need to figure out what size it is) I have one at home already but will need a second one.
So my question is what do i need to do to seal the inside part of the cooler to prevent liquid from getting into the insulated part of the cooler?
