1.5” Tri Clover Fermenter Blow-Off Tube

with 14" Thermowell

304 Stainless Steel


This is essentially two of our other product offerings combined into a single device:

·         1.5” Tri Clover Fermenter Blow-Off Tube (sku# 2787)

·         14” Stainless Steel Thermowell (sku# 2847)

This item works GREAT with the Chronical line of Ss Brewtech / Brewing Technologies fermenters!

Does NOT work with the BrewMaster series of Ss Chronical fermenters – they have a 3” Tri Clover port at the top of their lid - use SKU# 2849).

Fermenter Blow-Off component:

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 unwanted back pressure has formed behind the hose 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 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!

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

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

Stainless Steel Thermowell component:

·         Outer diameter: 3/8”

·         Inner diameter: 1/4”

·         Total thermowell length: 14” – long enough to reach WAY down into the vessel


·         All components are 304 Stainless Steel

·         Over-all Height is 19.5 inches

·         Over-all Length is 10.75 inches

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

Excellent Quality and Design 06/21/2021
By Tim Edwards
The NorCal tri clover blow off tube with thermowell is outstanding in all ways for my conical set-ups. It allows vertical thermowell install and blow off on lid while using one fitting. That leaves remaining fittings for spunding valve and dry hopping. I didn’t want thermowell on side of conical s because it takes a port than can now be used for tri clover sampling valve.

The quality of stainless, quality of welds and workmanship, and simple design make this a winner for me. NorCal pricing for this is bonus as other options are far more expensive e. My orders from NorCal are filled quickly.

Two thumbs up to NorCal for both products and service.

Solves problem with Spike CF-10 10/06/2020
By Philip Menzies
Great product. Lets you get your temperature probe down to an appropriate level in your fermenter. It solved a big problem for me with my Spike CF-10 Unitank that was supposed to be able to ferment batches from 5-10 gal. But at 5 to 5.5 gal Spike's thermowell wasn't immersed in the liquid. Fortunately NorCal was able to quickly create a version of this product with a 15" thermowell - the optimal depth for its positioning in the tank. Works well!

Great Solution 02/19/2019
By Mark Alfaro
This fits perfectly on my Stout Tanks fermenter. Easy to use and the tube drops perfectly at the edge of the fermenter. The thermowell is the perfect length to monitor a 5 gallon batch.
