Oxygen Diffusion Stone - 2 Micron

This Oxygen Diffusion Stone (also known as a Carb Stone or a Aeration Stone) is made of 2 micron stainless steel. It is designed for aerating your wort before pitching your yeast; properly aerated wort will promote healthy and fast fermentations reducing the amount of potential flaws in your brew. It is used with room air and an aquarium pump. For best results boil and rinse before first use.

Barbed fitting fits 1/4" I.D. tubing.
