Description

S-shaped airlocks are the "OG" airlocks for home beer and winemaking. They make it easy to spot fermentation activity, and have no loose peices to lose.

The advantage of this type of airlock is that they have a smaller chamber so you can more closely observe the CO2 rising and therefore the rate of fermentation. They are also handy when you are cooling a beer as there is less chance of sucking airlock water back into the fermentation. They cannot be cleaned manually if they get dirty during the ferment. That is why many homebrewers prefer 3-piece airlocks for the active portion of the ferment, when the krausen (foam) from fermentation might be pushed up into the airlock.

Please Note: Stopper Not Included.

I think it is easier to see the bubbles. With the upright ones the inner cap is never straight, hard to see the fluid level in the airlock.

Easier to see bubbles than the 3-piece
So far, I like this airlock much better than the 3-piece one I had. It's probably harder to clean, but not sure that's an issue yet.

Nice bubbler
Always like to keep these looking like new. These fit neatly to the carboy plugs and work well.

S-shaped Airlock
These are good. The only thing I'd complain about is that they are not very strong and can break if you twist them whilst trying to get them out of the stopper.

Works perfectly, a bit brittle
Not a lot of options out there. These things work perfectly until they break. I’ve had a few snap with very little force, attempting to twist pull them out of a bung.

I’ll continue to buy these, but I wish there was a more solid solution

I only use S shaped airlocks
I put just enough water in to fill the bottom U in the airlock. That minimizes back pressure while still maintaining an air lock.

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

Plugged up pretty easily. Ended up blowing off the jug and across the kitchen!
