Homebrew 1/4in Stainless Steel Thermowell and no. 7 Bung Stopper for Glass Carboy Fermentation Thermometer Probe;

Controlling temperature is vital for good fermentation, so use the G. Francis Homebrew 1/4" Stainless Steel Thermowell and #7 Bung Stopper for Glass Carboy Fermentation Temperature Thermometer Probe for accurate positioning and readings even deep inside the fermenting bucket. It keeps out contaminants and aeration and is compatible with standard glass carboys, temperature controllers, and airlocks. The thermowell is removable from the stopper to fit different sized configurations. The included #7 silicone stopper has an airlock hole to prevent your carboy from building up pressure. Dry the carboy surface and the stopper, place a probe inside the tube and then inside your beer fermentation vessel. The thermowell and stopper will stay secure once properly pressed into the carboy.
