MLT Cooler help

Hey all,

I made a MLT out of a Rubbermaid 10 gallon cooler (orange circle water cooler). However the thing leaks like crazy around the ball valve. I can't stop it. I have used several o-rings and different combinations of them but can't stop it. I even resorted to food grade silicone caulk on the outside around the ball valve without success. Any ideas of how to get this MLT working?

Thanks

Just built one today myself, put some water in it for awhile and no leaks. I followed this thread, so maybe it will help.

I bought some rubberized gasket material from home depot in the plumbing section. I cut it to fit and made my own gaskets since I couldn't find the right ones. I used 3 or 4 of them on each side in my mash tun/ball valve setup. Cranked tight with pliers, it only dripped a tiny bit occasionally. Then I used some

Buttloads of it. Like 5-10 times around the threads. All better. That's what cured my heatstick too.
