so i have a Colman extreme cooler, and i bought a bulk head off of northernbrewer.com
i picked up the smaller one, because the bigger one says a 1" min thickness and it wasn't that thick. so i installed it as the directions say, i only used one washer, but i have a very small leak, with the cooler over half way full and it sitting over two hours it didnt leak enough to "drip" but it was wet on the cooler.
what i worry about is the inside of the cooler, where the foam is, i dont want the mash to get in there and over time funk things up. oh i used thread tape too. anybody with some tips? i'm about to empty the cooler and take a picture.
the one thing i thought was strange, the large o-ring goes on the outside and the smaller one on the inside. the factory hole was just a little smaller then the small o-ring. just seems to be that the large one would go on the inside, anyway, ideas?
