American Sankey Tap.
This coupler fits D-System keg tap valves, which means it's exactly what you need to serve the majority of beers brewed in the United States and Canada.
It'll dispense Budweiser, Michelob, Busch, Miller Lite, Milwaukee's Best, Coors Light, Killian's, Sam Adams, Molson, Labatt, OV, Moosehead and so many more of the craft beers we love. This tap will hook up to the line on your co2 regulator with 5/16 tubing.
