Description

An old traditional style of airlock that is still preferred by wine makers during an ML fermentation and for longer term aging. A 3 piece style airlock (FE370) is preferred for active primary fermentation of sugar because they can be easily cleaned when they get dirty. The S-Shaped is better for long term aging because the water in the airlock has less surface area and will not evaporate as quickly. They are preferred for ML fermentation because they will show positive pressure, an indication that your ML fermentation (which are very slow and hard to detect) is working.

Please Note: Stopper Not Included.

Good product.
Purchased a few of these over time so I can have different batches in fermenters at the same time. Prefer these over the three piece airlocks.

Very practical air lock
Even though these air locks may seem flimsy compared to the three piece air locks, they work much better for me.
Not having to keep track of three pieces.
Even a teaspoon of liquid will still maintain an air lock

Not my favorite
Plugged up pretty easily. Ended up blowing off the jug and across the kitchen!

Seams need to be shaved.
There are sharp seams on the tube that goes into the stopper. However, there are easily scraped off with the side of a sharp knife then sanded with a little bit of polishing sandpaper. Price is reasonable

S shaped airlocks
These airlocks do exactly what they were designed to do. They work. They could be improved by the addition of a flange ( about the diameter of a penny ) at the first bend above where the stopper slides on.

It works at least once
It isn't too expensive, but will probably only work once well.
When everything starts pushing it's way up there, a few things get stuck to the sides in the "bulb" area. Starsan won't get that out either, and try getting a small brush to run through it without scratching the sides? Impossible.

Love these airlocks
This is my go-to airlock.
CLEANING: I'm a beer-hygiene freak and these are EASY to clean even when heavily fouled after a vigorous primary: Strong, warm PBW solution, a quick soak and a shake or two ==> clean as the day you bought them. Finish them off with a StarSan soak and Bob's your uncle.

LIQUID BACKWASH: If you're sucking liquid into your carboy while cooling then you're adding too much liquid. I generally use StarSan as the liquid except where high CO2 production rates cause too much foaming. Like Mike E. suggests above, use vodka and any problems are over.

CO2 MONITORING: This is the real beauty of these air-locks. You can easily detect even the most minute CO2 production. This is not essential but I love watching my beer ferment.

Great for secondary, don't use for primary ferment
Difficult to clean, but dump some vodka in there and forget it.
