The Tapcooler extension tube is perfectly suited to provide the counter pressure filler a bit of extra space for the bottles where there is not enough room to fit them directly under the tap. The one end of the connection hose is designed to screw into the top of the filler unit and the other end of the tube is designed to screw into the filler unit's removable tap nozzle insert. Includes two small o-rings to seal the extension line on either end (there is already an o-ring seal inside the filler unit when the tap nozzle insert is removed).
