🏠 Homebrew Thermowell Fermenter Heating Boiler Review

These thermowells are ideal for Johnson A419, Penn A421 or any Inkbird temperature controller. Its large tubular design is ideal for the large temperature sensors that come with these traditional regulators.

Bought 2 of these for my kegmenters. One was fine and the other had a tiny hole that sprayed a fine mist under pressure. In fact, it is almost visible in the weld. I ordered a replacement, brought it to the farm and this one has the exact same hole. Wouldn't recommend it.

This thermowell arrived very well packaged from the manufacturer and fits perfectly with my home fermenter (Spike Brewing Flex+). I was happy to see that the actual piece arrived much shinier/polished than the product photo online. I was worried the surface would be rough (judging by the photos) but everything turned out to be fine. I will buy again and recommend. Excellent price.
