Review on Stainless Thermowell Thermometer Homebrew Accessories by Joe Glass

This is a great protective case but it was a chore to install in my 5 gallon plastic beer fermentation bucket until I figured it out. I also saw installation instructions online from the thermowell manufacturer and here they are: The silicone o-ring should be on the inside of the bucket and the large steel washer should be on the outside of the bucket. The trick to avoid leaks is to additionally wrap the threads with PTFE adhesive tape (available in hardware stores, very cheap). The PTFE tape is hygienic and will not affect your drink. I found the silicone o-ring to be too small in OD, so I also bought a silicone garden hose washer to replace the o-ring. Be sure to purchase a silicone washer (not the standard hard or soft rubber) as this is suitable for direct food contact.
