Three Piece Airlock Top quality cylindrical lock with floating bubbler
The 3-Piece airlock is the best choice for the primary fermenter, since it comes apart for easy cleaning in the event of a blow-off.
Fill to the line with boiled water or sanitizer to create a closed fermenting system that allows CO2 to escape, but does not allow air back in to contaminate your beer or wine.
Includes body, piston, and vented cap. Easy to disassemble and clean out in the event of a blow-off.
This 3 Piece airlock is a good choice for both wine and beer, and uses a three piece airlock design. Fill approximately half-way with a water/sanitizer mixture. The water acts as a environmental barrier keeping airborne contaminants out of your batch, but still allowing gasses to escape the fermentation
Simply remove the cap, fill the cylinder about halfway (to the imprinted line) with water or sanitizer, and replace the cap. 3-piece airlocks are easy to clean with an airlock brush if the fermentation back up into the airlock.
This is the airlock that many homebrewers end up using. You'll prefer this model for primary fermentation for a few reasons. You can also use this airlock for both primary and secondary fermentation.
Always sanitize (inside and out) before using.
