Perlick's new 600 series of faucets builds on the high standards associated with the Perlick brand. The new 630SS faucet is made from 304 stainless steel. It's forward sealing design is unique in both appearance and function. A revolutionary ball and floating front seal design prevents beer from being exposed to air. As a result, the handle level doesn't stick, and there is no build up of mold and bacteria in the faucet body. Fewer internal parts in the 630SS means better reliability.
