Product details:

Perlick Perl Forward Sealing Stainless Steel Faucet features a sealing design that seals the faucet near the spout end of the faucet, not at the rear like most other designs. This means there is less faucet area exposed to keep clean, and that area is easier to clean. This brass plated shank is 4-1/8 inch long measured from the end of the threading to the end where the faucet attaches. A shank is to attach a beer line to a faucet. The shank is mounted through a 1 inch hole in a wall, refrigerator door, cabinet, etc. The shank comes with a black flange on the front and a compression ring on the back. The compression ring is to secure the shank to the mounting surface. All shanks come fitted with a tail piece for beer line connection.
