Material and durability Made entirely from corrosionresistant 304 stainless steel for long service life temperature resistance for use with hot wort and cleaning cycles Solid construction reduces risk of contamination compared with porous ceramic or plastic stones Fine bubble diffusion for faster, more consistent results Includes two inline diffusion stones, 0.5 micrometre and 2 micrometre, each with millions of tiny pores 0.5 µm produces very fine bubbles for rapid and uniform oxygen transfer into wort 2 µm provides slightly larger bubbles for efficient carbonation of beer or seltzer Designed to improve oxygenation before fermentation and to deliver consistent carbonation for finished beverages Easy, flexible connections Attaches quickly with standard hose fittings to kettles, pumps, and wort chillers Simple inline setup lets you place the stone where it performs without permanent modification to equipment Can be cleaned and sanitized in place or removed for deep cleaning Why brewers choose this diffusion stone Solves common problems: speeds yeast startup through better oxygenation, reduces inconsistent carbonation, and withstands brewing conditions without degrading Helps produce cleaner, more repeatable fermentation and carbonation results for smallscale and DIY brewers Versatile for both beer and seltzer applications Typical use scenarios Prefermentation wort oxygenation: connect to your pump or kettle to dissolve oxygen quickly and evenly before pitching yeast Carbonating seltzer or beer: use the 2 µm stone inline to achieve efficient, controllable carbonation for bottled or kegged beverages Homebrewing system integration: install between kettle and wort chiller or in a recirculation line to add oxygen or CO2 where needed Specifications and compatibility Material: 304 stainless steel (anticorrosion, temperature resistant) Included stones: 0.5 micrometre and 2 micrometre inline diffusion stones Connection: hosecompatible for kettles, pumps, wort chillers Intended use: DIY beer and seltzer water brewing for improved oxygenation and carbonation Practical benefits Faster yeast activation and healthier fermentations More consistent carbonation and mouthfeel in finished beverages Durable, easytoclean design that integrates with common homebrewing equipment
