Torpedo Keg Buoy Floating Dip Tube
In the world of continuous improvement, you’ll find changes to things that you didn’t think needed improvement. If they’re good improvements, they’ll change how you use it. The floating dip tube was one of those unexpected changes to the simple homebrew keg. The keg has so few pieces to it, and has such a simple job. It’s surprising that they took something as boring as a metal tube and found something creative and new to do with it.
The dip tube is the passageway for the beer from inside the keg to outside. The standard dip tube is all about being in the right position at the end of the beer- at the bottom to get the last drop of beer out. The floating dip tube turns that upside down and instead of being at the bottom the whole time, sits at the top of the beer as the level continuously changes. The rigid steel tube is replaced by flexible silicone tubing with the open end attached to a stainless float ball. The float then sits on the top of the beer, and as the beer level goes down, the float of course goes with it, and the tubing allows you to pull beer whether the keg is at its fullest or at its lowest.
The Torpedo Keg Buoy Floating Dip Tube starts with a short 2” tube. This tube goes into the keg with the same interface as a regular dip tube with a flared end and an o-ring that gets compressed when you screw down the keg post. Once that’s installed, you attach the 23.5” long silicone tubing from inside the keg. Lastly, the float has a short 1” length of stainless tube attached to it with a ring. The silicone tubing then slides over this short stainless tube to complete the setup. With this configuration, it pulls beer from the top, while the precipitate sinks down below it to the bottom of the keg.
