The shank creates a stable mounting place for the faucet. It is the transition point between the beer line and the faucet. Shanks come in a variety of lengths. The shank is an excellent conductor of cold between where the beer is stored and the faucet. However it is important a shank does not go through thick walls where the beer would be allowed to warm up.
Types:
Straight Shank
Requires additional fittings to connect beer line: hex nut (874), tailpiece (related to hose being used), neoprene washer (759) and clamp (related to hose being used).
Nipple Shank
Built-in tailpiece for easy beer line connection, only a clamp required.
Shank with Bent Tube
Utilizes elongated ¼” OD tube extending down through tower into kegerator. Threaded fitting on end allows for easy connection with hex nut and tailpiece inside kegerator.
Materials:
Chrome Plated Brass
Traditionally in the U.S. most plumbing and liquid flow fittings have been brass with chrome plating. Shanks made of brass are economical in installations. Use for beer only.
Stainless Steel
Stainless steel has been the primary material of choice in many parts of the world for years; it is an excellent material for maintaining product purity and for long-term durability in installations. Use for beer, wine, and cider applications.
Lexan
Plastic is good for cider and wine applications, but never for beer.
Bores:
The drilled hole in the center of the shank the beer passes through is referred to as the “bore.” Most beer shanks are available with either 3/16” I.D. (inside diameter) bore or ¼” I.D. bore.
