Great pair of air locks complete with bungs that work a treat. They have a top chamber to catch any overflow and have a cap on top to do away with the cotton wool.

While making crab-apple wine, I found that my old airlocks and corks needed replacing. These Bubbler air locks have rubber bungs included, so make very useful replacements. They are now in use with a batch of crab-apple wine in standard demi-johns.
