The 3-piece airlock is standard equipment in the brewer's arsenal. Made of 3 pieces (of course), this airlock can be disassembled and cleaned, unlike the traditional double bubble airlocks. Simply fill the airlock past the holes in the center piece with sanitizer or water. Because of their design, they have less of a chance of sucking liquid back into the fermenter than the traditional double bubble airlocks.

They can also be easily made into a blowoff tube by attaching some ½" ID tubing to the center of the main airlock body. You can never have too many airlocks!

Airlock
I used this device successfully with my fermentation and it kept my beer free of contaminant.

Air lock
Very good product. Just be very careful when attaching the air lock to the vessel. One of my new air locks shattered at the stem when I was attaching it.
