Airlocks and Bungs

These are designed to fit the most common sizes.

They are essential pieces of homebrew kit and do need replacing fairly often.

Some old homebrew books recommend that you put steriliser in the airlock, we never bother, it gets blown out by the gas anyway!

Put a bit of water in the airlock and leave it alone, it should be obvious when it bubbles!

Fits most demi johns, if you have the old screw neck ones you might find they're too big.

The most popular type of airlock and give a nice "plop" sound as they bubble!
