This bottle filler is made of durable plastic, and has a spring loaded ball valve at the tip. Simply push the filler down on the bottom of the bottle until the beer reaches the top, and after removing the filler, the perfect amount of headspace is created. Choose between 1/2" or 3/8". The 1/2" bottle filler uses 1/2" tubing and the 3/8" bottle filler uses 5/16" tubing.
