3-Piece Airlock With #6.5 Rubber Bung For Fermentation Vessels

Description

This 3-piece airlock is ideal for primary fermenters, as it allows you to monitor the CO2 release from the fermenter. Fill to line with boiled water or sanitizer to create a closed system, which allows CO2 to escape, but doesn’t allow air back in to contaminate your wine or beer.  Comes with a #6.5 rubber stopper for carboys and jugs.
