This fits many American commercial beer kegs, including most microbrews. Includes a 5/16" gas-in hose barb and no beer nipple. Order adapter parts separately below if you want to adapt this to a system that uses home brewing ball-lock kegs. This US made Taprite unit is made of nickel plated brass for use with beer only (not for cider, wine, or coffee). Made in USA by Taprite.
