This 3" x 15" Copper Reflux Moonshine Still Pipe comes with a 3" stainless ferrule welded on to one end. Also includes a 3" tri clamp and gasket. This is not a complete column. You can use this with some more copper pipe and some solder to build your own column. This will connect to any 3" tri clamp ferrule on any moonshine still boiler that are sold with a 3" tri clamp connection. This copper pipe is type L, which is much heavier that the cheap type DWV or type M.
