Chrome-plated brass with 3/16" barb for connecting standard 3/16 ID beverage tubing to a beer shank or sankey coupler. This is the ideal size for most home kegerators where the liquid lines are relatively short. The ID of this tubing will help restrict the flow and prevent foaming in the glass.Requires a Hex Nut or Wing Nut for connection to a beer shank, as well as a neoprene washer; sold separately here. Can also be attached to a commercial sankey coupler.Also available in Stainless Steel.
