This stainless 4inch tri-clover ball lock lid will enable you to turn your kegmenter into a uni tank, pressurisable fermenter or so it can be used as a keg.

This lid comes with a red pressure relief valve (that opens at 2.5bar - compatible thread to Cornelius type PRVs).  The lid has accurately machined gas and liquid posts. 

This lid is ideally suited to also fermenting under pressure so you can use a spunding valve/adjustable pressure relief valve so you can naturally carbonate during primary fermentation.

This is the easy way to have continuous soda water on tap. Don't waste your time with Sodastream or other more expensive carbonators. This simple device makes it easy to have continuous carbonated soda water fed from your mains water supply.
