This stainless elbow attaches to the 6" TC center lid port on the BREWHA 4-in-1 fermenters (1.5BBL, 3BBL, 5BBL, 7BBL) and has a 5" hose barb. With the lid slightly elevated and through use of an inline fan and steam tolerant ducting, steam vapor from the boil can be drawn away and directed outside the building or into a condenser.
