Bubbler Airlock With Cap

Airlocks are useful for not only indicating if fermentation is taking place, they enable CO2 to escape safely, while keeping air and air-borne bacteria and yeasts out of your brews. Comes complete with a cap to keep flies out. To use, simply insert into a grommet and half-fill the lower-most bulbs with sterilising solution or a neutral spirit, such as vodka.
