Looking to get mare temperature control out of your brew? Add a weld less thermowell to your kettle, stock pot, mash tune, keg, kegged, or any other device you choose. The inlet accepts 1/2 inch male pipe thread and seals using a 3 piece weld less fitting with 304 stainless steel parts and a food grade high temp silicone washer. A weld less thermowell protects your thermometer and best of all it will also accept the digital temp controller on the Johnson Controls A419 controllers often used in home brewing.
