Product Details

Fill with water and insert in drilled stopper or bung to vent gases during fermentation. "Bubbler" style airlock makes a gratifying "bloop" noise during active fermentation. It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.

Quality airlock
These work great. I love listening to the bloop bloop sound as it ferments. I haven't needed to clean mine yet... not really sure why you would need to, unless you have a lot of overflow or something.

Great for carboy or barrel!
This airlock is great for second fermentation while making beer and also great for my 50 gal. barrel when I make hard cider! My wife bought this airlock with the Big Mouth Bubbler for myself as a Christmas gift. After looking at the design of the Big Mouth Bubbler lid, I decided I did not need an airlock. I filled the recessed plastic carboy lid with Star san, and snapped on the white plastic vented cap that came with the carboy. BLUP, BLUP, BLUP...It worked just fine! However, I use this type of airlock during second stage fermentation with standard carboys, never during first because of possible blow-offs. I once made the mistake of using it on a first fermentation and it whistled like a tea kettle because of too much pressure. Luckily I found it before I had a huge mess and changed to a blow off hose.

great basic air lock
This bubbler air lock works great for lower-yeast beers. Get the drilled carboy bung stopper and it pulls out easily. For anything too exciting (an over-bubbly brew) buy a hose and a bucket and make your own airlock.

No problems here
What on earth are other people doing to their airlocks? I've had mine for about a year now and nary a crack in sight. Granted, on occasion they do get a little stuck, but I just twist them back and forth gently until they come unstuck.

it's an airlock
Exactly what it looks like. Easy to take apart and clean. Does the job.

Much easier to see fermentation activity than with a 3 piece.
When your brew is getting down to the end of fermentation, these still show obvious activity where the 3 piece ones don't bubble visibly, so the are nearly impossible to tell if anything is happening. No matter how slow your brew is working, assuming of course your fermenter is all sealed up, these show activity. You can watch as each bubble is slowly pushes liquid through the S Trap.I NEVER use Star San in these btw. It foams and blows out. Vodka only for me.

im brewing the Irish Ale and at almost 48 hours post-brew -- still little to no bubbling, and the water in the airlock fluctuates back and forth... Still normal?
Andrew B on Mar 2, 2016
BEST ANSWER: The water going back and forth is from temp. change. It's possible for there to be a lag before fermentation starts but I've never had one 48 hours. Maybe the yeast you pitched is dead or you didn't pitch enough.
Can the bubbler airlock be used with small batch kits?
R M on Jan 12, 2016
BEST ANSWER: It could be, yes. If you use the 38 mm screw caps, those will only work with the three piece airlock. But if you have a rubber stopper in your fermentor, a three piece or S-bubble type will work in those. I hope that clarifies! Cheers!
So I put the sanitizer solution in my airlock and made sure that both sides were only filled to the "max" line on each side. No excess. But now that my beer has been sitting for about half an hour the air lock is almost full on one side and empty on the other. Why is this? How do I fix this?
B R on Dec 27, 2015
BEST ANSWER: Hello Brian,

Thank you for choosing Northern Brewer! There is nothing to fix. That is what that airlock does when it comes under the pressure of CO2 from the fermentation going on inside of your fermentation vessel. Nothing to do here but sit back, relax, and let the fermentation commence!
Do you keep the red cap on the airlock during fermentation? thanks Dave
C H on Jan 1, 2016
BEST ANSWER: Hi Dave,

Sure, you can. It's not really that important. I've lost most of my red caps! They're nice for keeping fruit flies out of the airlock, but that's about it.

Cheers,

Charles
I got 2 of these with my starter kit. Have used them on my first 5 brews. I went out and bought a new S shaped airlock yesterday that came with a clear cap that has three holes in the cap. The red caps do not appear to have holes? Was I supposed to put holes in the cap?
T S on Apr 24, 2016
BEST ANSWER: The red caps do not have holes in them. The CO2 is allowed to escape from where the cap meets the bubbler airlock. I hope that this helps!
