2 Micron diffusion stone used primarily in wort aeration. Larger-sized holes make it easier for air pumps to diffuse oxygen into the wort. Full 316 Stainless construction.
Avoid touching the stone, as this can clog the small holes. If this occurs, boil the stone for 3-5 minutes; this should remove buildups. To sanitize before use, run the system through sanitizer for 5 or so minutes before use.
Features a 1/4" Barb.
