Product Overview

Bundle of Two Double Bubble Airlock S-Locks with dust cap  and Carboy Bungs that fit Glass Carboys (Stoppers do not fit PET Carboys)

When filled with water allows Co2 gas to bubble out and prevents air from getting in. Enclosed design allows for slower evaporation from airlock bubble.

  • Twin Bubble Airlock with Carboy Bung
  • Allows for slower evaporation
  •  for 3, 5, 6 and 6.5 Gallon Glass Carboys (Stoppers do not fit PET Carboys)

A double bubbler offers advantages that other airlocks simply can’t. It will show the difference between the inside air pressure and the outside air pressure (a great way to gauge fermenting activity), and it can also prevent “suck back” (a term used for when liquid in the airlock is sucked into the fermenter due to temperature changes). Not to mention watching the bubbles is a great way to pass the time while you’re waiting for your beer to complete fermentation.

Always sanitize (inside and out) before using.
