This Avantco 178COUPLER provides you with a simple way to tap a keg filled with nationally-renowned or locally-sourced brews! It is used with "D" system (American Sankey) keg valves which is the most common system used in the United States, ensuring the highest degree of compatibility. Major breweries like Anheuser-Busch, Miller, Molson-Coors, Labatt, and most craft breweries use this system to infuse their beer with the proper amount of CO2 while delivering it smoothly from keg to tap! An integrated pressure relief valve provides you with added safety and peace of mind by ensuring the gas flow is cut off if the pressure gets too high.
