This Type D Sankey Coupler fits 99% of American commercial beer kegs. Includes ¼" beer and gas hose nipples, and a pressure relief valve. Made of nickel plated brass.
This includes a ¼" side gas hose nipple. Some commercial kegerators use 5/16" interior diameter gas tubing. To adapt this coupler to fit the larger diameter gas hose (if that is what you have) order optional nipple X91.
