Fill with water and insert in drilled stopper or bung to vent gases during fermentation. Includes body, piston, and vented cap. This airlock is easy to disassemble and clean out in the event of a blow-off.
It's easy to use and to clean, and does a good job of making sure that there's no backflow into the batch in progress. I have a few of these on hand.
Excellent. Works as described.
Great item. Easy to clean. I really like these.
I ordered the “Siphonless Big Mouth Bubbler” to experiment with fermenting for the first time. Ultimately, I decided to return it. Northern Brewer’s return policy is clear and I paid for my own shipping. I just didn’t realize how expensive it would be to ship back such a large package. It made the refund almost worthless. I wouldn’t encourage anyone starting out with fermenting to order from this site because of the high return shipping charges. I did contact customer service to get a refund since it hadn’t arrived after some weeks and they refunded me promptly.
Does the job (:
