Perlick's 630SS Stainless Steel, Forward Sealing Beer and Wine Faucet is unique in both appearance and function. Perlick's revolutionary ball and floating O-ring design prevents beer from being exposed to air. As a result, the handle lever doesn't stick, and there is no build-up of mold and bacteria in the faucet body. The micro-finished interior produces a smooth flow with less foaming ensuring a perfect pour every time. Fewer internal parts means better reliability. Easy to clean - may be cleaned in place - saves time and money.The ultimate upgrade for your existing kegerator or a top of the line choice for your kegerator or keezer build.If mounting without an existing connection, it requires a Beer Shank with faucet coupling nut, Tailpiece, Tailpiece Hex Nut, Neoprene Washer, and Tap Handle, sold separately here. Be sure to choose a shank long enough for your application.Shanks and Tailpieces are also available in stainless steel.
