Carboy Plug Locking Cap

thingiverse

We brew our own beer at home and have encountered that annoying problem where the plug loses its seal and pops out of the mouth of the carboy, but we're in luck because SlightlyOddGuy Industries has come up with a solution - the SlightlyOdd Carboy Plug Locking Cap. This brilliant cap fits snugly over plugs sizes 5-6.5 and screws directly onto the threads on our growler or carboy, ensuring a tight seal that prevents any leakage or contamination. The best part is that it also features a large enough hole in the center to accommodate any type of outrageous valve system we can imagine. Say goodbye to faulty plugs and hello to perfectly sealed brews with the SlightlyOdd Carboy Plug Locking Cap, which fits most growler sizes and even 1-gallon carboys.
