Here is everything you need to convert a 5-gal Igloo cooler into a mash tun. All metal metal parts are stainless steel. Included is a 9” domed false bottom, a high-flow pickup elbow, a stand-off tripod to prevent dome collapse (yes, it’s stainless), a 1/2” silicone transfer tube, a high-flow bulkhead fitting, a 1/2” NPT nipple to get the ball valve away from the cooler, a 1/2” ball valve, and buyers choice — a 1/2” Type F camlock male fitting or a 1/2” hose barb. $35 plus shipping. (I’ll throw in the Igloo cooler for free if you want to pick it up from me in north Alabama.)
