Diffusion Stone 0.5 Micron

Diffusion Stone 0.5 Micron

This can be used for either carbonation or aeration. 

For carbonation you would put this on the end of a gas line, hook up to a co2 source and insert into your keg.  We have corny keg lids built for this purpose specifically here

You can also use this to aerate your wort prior to fermentation. Hook up to a gas line and oxygen source and then bubble into yoru cooled wort before adding the yeast.
Yeast loves oxygenated wort - there will be less lag time before the action starts cranking and your yeast will be happier and healthier which equals better beer!

The barb is 6mm.
