This stainless steel Kegco shank is 3 1/2" long measured from the end of the threading to the end where the faucet attaches. Stainless Steel has a strongly bonded oxide layer, so it is less susceptible to attack by acids, making it ideal for wine and cider dispensing in addition to beer. A shank is used to attach a beer line to a faucet. The shank is mounted through a 1" hole in a wall, refrigerator door, cabinet, etc. The stainless steel shank comes with a black flange on the front and a compression ring on the back. The compression ring is used to secure the shank to the mounting surface. All shanks come fitted with a tail piece for beer line connection. The shank has a 3/16" hose nipple to attach a standard beer line. Faucet is not included. Larger and smaller sizes are available. NSF approved.
