This Three Piece Airlock enables a desirable closed fermentation keeping the beer away from the
contamination from bacteria and other microorganisms.

Fill the airlock with pre-boiled water, or sanitizer solution and then insert it into the pre-drilled
hole/bung on your fermenter. The airlock will allow CO2 to blow off but not let any O2 or bacteria
into your fermenter.
