Tri Clover Fermenter Blow-Off Tube

1.5" TC x 10” Long x 1/2" Diameter

304 Stainless Steel


So you have that nice, shiny conical fermenter. You just brewed a batch of beer, and you set up a blow-off tube attached to the top of your fermenter, terminating into a jar filled with sanitized water.

Everything looks great… you go to bed.

You check on your baby the next morning only to find that the blow-off hose crimped upon itself. Your wort is fermenting, but back pressure has formed behind the crimp.

Dang it! If only there was a way to keep that from happening!

NorCal Brewing Solutions to the rescue!

Our fermenter blow-off tube replaces soft hose with a METAL arm that clamps to the top of your fermenter with a Tri Clover clamp. The entire arm is made of 304 stainless steel extending all the way past the edge of your fermenter.

Simply attach an inexpensive 1/2" inner diameter hose (plain vinyl works fine) and drop it the hose straight down into your sanitized water jar.

Since your hose now falls straight up and down vertically, there is NO WAY IT CAN CRIMP ITSELF!


·         All components are 304 Stainless Steel

·         Over-all Height is 3.6 inches

·         Length of tube (from outside edge of 90 degree angle to outside edge of 90 degree angle) is 9.25 inches

·         Over-all Length is 10 inches

·         Tube is .5” outer diameter, accepts any type of .5” inner diameter blow-off hose

·         Tri-clover connection on fermenter connection end attaches with 1.5” tri clover clamp (sold separately) and gasket (sold separately)

Quality of Life Purchase 11/09/2021
By Tyler Conn
I would personally consider this a guilty pleasure purchase for my cold side equipment. A bit unnecessary but ultimately an amazing quality of life enhancement to my brew days. It is hard to not feel joy when watching a Kviek fermentation bubble away through this attachment. This blow off tube replaces my previous 3 piece airlock which I was always losing a piece or two between brews. Now, I have no fear of a blow out or clogged airlock, and it is easier than ever to clean out and sanitize. Awesome product!

Great solution 07/15/2019
By Rob Woods
Works well on my SS Brewtech 14 gal chronical. Allows me to run a blow-off using 1/2 inch silicon hose without worrying about the hose kinking, leading to a pressure build up in the fermenter. The sizing is great, overhangs the lid by enough for the hose to take a straight path to the vessel used as an airlock. Norcal were excellent, got this to me in Australia very quickly. Can't get a similar solution locally, kudos.

Solid Piece/ Easy to Clean/ Affordable 09/27/2018
By Nate Reynolds
Purchased this for my new Spike CF5. Much more affordable than the Spike version. It's currently hooked up- no leaks, and bubbling away into a blow-off container. This piece is solid and easy to clean & sanitize.
Note- for the size, it hangs over a 5 gallon conical. If you have a larger conical, say 15 gallons or more, it may not hang over the side- but I do not think this will affect performance.
