Coleman Cooler Mash Tun

I think I found the easiest way to convert a Coleman cooler into a mash tun.

Steps:
1. Take the Spigot Assembly out of the cooler.
2. With a small die grinder, remove the "spigot/valve" part (where you would push the button to drain the cooler)
3. With a 1/8 NPT tap, cut threads into the outside (smaller) portion of modified spigot.
4. With a 3/8 NPT tap, cut threads into the inside (bigger) portion.
5. Thread your favorite pipe thread fittings/valves to the outside of your newly threaded bulkhead fitting. Choose wisely though, I'm not sure how many opportunities you get screwing and unscrewing metal fittings into the plastic.
6. Replace the newly modified fitting into the cooler. Fill with water to check for leaks. I didn't even need to put Teflon tape on the threads, the torque on the brass fittings into the plastic was good enough.
7. Attach your manifold, stainless braided hose or whatever your using as a filter to the inside of the fitting.

Cost: Nothing, although I already had the taps, cooler and fittings laying around the shop.

Sorry that I'm bringing back this old post but I have same issue with my Coleman cooler, no kits fits it, The question here is if the plastic parts of the spigot and the original o-ring can handle hot liquids without any unwanted stuff getting to the beer (from the plastic parts and I don't think the o-ring is a silicone one).

This is very simple.

1. Buy cooler kit, ball valve, and stainless braid from barginfittings.
2. Remove spigot. keep the rummer grommet from spigot.
3. install cooler kit
4. attach stainless braid on inside, and ball valve on the outside.

Voila a damn fine mash/lauter tun.
