Aeration stone

Aeration and carbonation stone

Stainless steel. Can be used for aeration and carbonation. Mesh diameter 0.5 microns. 7mm hose connection.

This 0.5 micron diffusion stone easily attaches to a 50cm tube at the "gas inlet" end of your keg for faster gassing. The small bubbles the stone creates help to saturate your beer. Also great for oxygenation! Remember not to touch the stone with your fingers, wear gloves.

Stone clogged?
One effective way to clean a stone is to pump CO2 through it at about 1-2 psi and boil the stone in an electric kettle for at least 5 minutes. Then store it in a sealed bag until next use.
