I had a blowout on my bucket last time I fermented in it, so I want to use a blowoff tube the next time to mitigate that, and this elbow looks like it will make that setup easy.

12gallon batches in my 14 gal brew bucket still blows airlock out. Hopefully this will fix that.

Sometimes fermentation takes off more vigorously than airlock will allow

Warped my lid on a vigorous ferment with airlock; never again!
Mark Barry on May 18, 2019
Better option than the 3 piece airlock since it will allow the fermenter to be placed in a smaller area.

This will work for the regular SS Brewtech 7 gallon Brew Bucket right? I do NOT have the brew master edition...
John Coughlin on Dec 13, 2018
BEST ANSWER: Yes it will. The only difference between the regular and brewmaster edition of the 7g brew bucket is the addition of a thermowell and provided digital thermometer. The lids are identical.
Cold Crash with Blow Off Barb? Any one have a good (not too complicated) suggestion for cold crashing with the barb still attached to the brew bucket?
Timothy M Wickham on Apr 20, 2021
BEST ANSWER: I have it hosed down to a 1L flask, cold crash as if it were a normal airlock. It shouldn't make a difference if it's on. That's how I do it, haven't noticed any issues.

Must have for Brew Bucket
This is a must have if you have the SS Brew Bucket. This makes it easier to manage possible overflow during early primary fermentation and it can also be used for closed pressure transfers into your kegs after fermentation is over. For $20 this is an easy and inexpensive upgrade..

Blow off connection
Great product, although it's a pain to remove if you want to install a regular S Lock after primary is almost done. I usually switch to S Lock, so I can crash without sucking in liquid/air.

Excellent Quality
I bought this for my SS fermenter. The barb that comes with it kept getting cut in half by the sharp metal this is awesome.

Simple and effective
Works great, used 1/2” silicone blowoff for initial “heavy” yeast activity then switched an airlock attachment I made by threading a piece of the 1/2” silicone through a PVC elbow to add rigidity. A #4 silicone stopper fit inside to fit the airlock onto. Works great.

Great Add on
Nice for bigger beers and to add some CO2 for closed transfer. Works great.

I dislike stoppers and bubbler type air locks for several reasons. This thing makes the brew bucket more compact and IMHO more stable with a range of fermentation.
I haven't tried it yet myself, but I've seen folks on YouTube use this fitting to close transfer beer into a keg with co2 from the brew bucket.

Perfect for fermenting and CO2 transfer
I brewed three batches and kept each at the specific temperature steps with the FTSs during repeated heat waves during the month.

Each batch was perfect! And cleaning the brew Bucket is so easy!

I recommend adding the right angle fitting to use a blow-off tube during fermenting, then attached it to CO2 to transfer into a keg to minimize oxidation.

Great product
Perfect for my Ss 7 gal fermentor. Used it to insert CO2 to transfer beer to keg and as blow off barb in fermentation period.
