While the f15 fermenter is not new the gasket and how it fits on the tank is new. We call the new fermenter the f15b. It is designed for our new blue gasket. See the gasket page for more details about the gasket. This new design is easier to install and therefore it is easier to use. We still believe a gasket is not needed but you have asked for a better design and we complied with your wishes.
The fermenter ships ready to brew and is our best design for 10 gallon recipes. Included are a 1" lead free brass bottom ball valve, 1/2" lead free brass racking port ball valve, lid, stand plus three 1/2" screw in plugs. There are two threads in the lid and one below the label for a thermometer. The thermometer is not included. The plastic is a full 5/16" thick. The fermenter is 44 1/2" tall x 18 3/4" wide. Ships in one oversize box
