Diffusion Stone 1/4″ Male Flare .5 Micron for Carbonation/Oxygenation

 Easier to Sanitize Design 
We added threads instead of a barb and now you can use the fittings you see at the bottom of this page to connect and disconnect your tubing. This allows you to place the stone by itself directly in a pot of boiling water to sanitize. Easy.

316 Stainless
1/2″ diameter. Stone is 1″ in length. Overall length is 1 7/8″
