0.5 Micron Stainless Steel Diffusion Stone/Air Stone

This 0.5 micron diffusion stone can also be attached to the end of your "gas in" on your keg with 50cm of tubing to rapidly speed up carbonation. Ideal for use with our carbonation keg lids. CLEANING: This stone can be sanitised in boiling water and cleaned in a non-rinse sanitiser while running CO2 or air through the stone. If the pores in the stone get blocked from handling give a 10 second dip in hydrocloric acid before rinsing with water.
