This stainless 4" tri-clover ball lock lid is a direct replacement to the lid that comes on our kegmenters. 

Use:

As a stainless steel fermenter that is easy to clean

Great choice for 5 gallon fermentations

Easy to pressurize the kegmenter after fermentation to push through a filter and into another keg

Fermenting under pressure, allowing CO2 to exit via the relief valve, reduces esters and fusel alcohol production allowing you to ferment at warmer temperatures

As a cellar keg for topping up barrels
