The Kegco Low Profile 2-3/8" tall coupler is the perfect keg tapping solution for space challenged places where you need to tap a keg. The short design requires 4" less space than standard lever handle couplers. It is compatible with all domestic brand "D" system Sankey kegs and is easy to use - to tap, simply pull out and then down on the lever handle. This coupler features a nickel-plated forged brass body with a sanitary stainless steel probe, a 1/4" I.D. beer outlet barb, and a 3/8" I.D. gas input barb. A 55-psi pressure relief valve allows over-pressurized gas to escape before it can enter your keg.
