Warped my lid on a vigorous ferment with airlock; never again!

Better option than the 3 piece airlock since it will allow the fermenter to be placed in a smaller area.

Only available for FTSs lid

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: I use it regularly on the standard (regular) brewbucket with great success. I thought it was quite pricey, but it has been worth it. I do not ferment any batches without this in place as part of my blow-off valve.

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.

blow off barbed elbow for SS brewtech fermenters
Good Product. Works well and is well made from high quality material. But, It is over-priced in my opinion.
