Our 12" Stainless Steel Domed False Bottom is used in 10 Gallon Igloo Cooler. The hole in the center measures 7/8".
The 16% open design contributes to better efficiency and a clearer sparge.
Add-on our false bottom assembly which includes all fittings from the false bottom through to the one piece stainless steel ball valve.
Our compression fitting design incorporates a stainless steel tube which essentially "Hard Plumbs" the false bottom into place. The false bottom will NOT float.
The fittings are a mixture of brass and stainless steel. Currently (June 2013), the tube, nut and ball valve are stainless steel and the elbow, hose barb, bulkhead and compression fittings are brass. We've looked at the possibility of making everything stainless steel on this and determined it is simply not cost efficient. HOWEVER, if you are interested in all stainless steel, we recommend going with a pot over the cooler as a mash tun. Here is one example.
If you are mashing in a cooler, this is the premier false bottom for you
