Carbonating Stone with 1/4" Barb, 2 micron

This stone has less resistance and therefore has an application where you don't want to use tube clamps to attach it to tubing. You can use this 2 Micron Stone to carbonate beer or to create an oxygen system for your yeast. Either way, this versatile stone will make your life easier. Note: To prevent the pores from getting clogged, Midwest recommends not handling the porous end directly with your fingers.
