Ss304 Sintered Carbonation Stone Beer Brewing Equipment Pipe Fittings

SS304/316L Sintered Carbonation Stone (NPT Thread, 6"/8" Length)

Engineered for rapid, efficient, and consistent CO2 or oxygen diffusion, the Aomite Sintered Carbonation Stone is an essential component for commercial brite tanks and fermentation systems.

Manufactured from premium AISI 304 or 316L stainless steel, this robust aeration stone utilizes a micro-porous sintered body to create millions of ultra-fine bubbles, maximizing gas absorption into beer, wine, or beverages. Designed with an NPT threaded connection for secure integration into tank ports, it is available in standard 6-inch or 8-inch lengths, with outer diameters (OD) ranging from 20mm to 38mm. Conforming to stringent 3A, DIN, and BPE sanitary standards, our carb stones withstand rigorous CIP cleaning and are available for global OEM bulk supply.

Why is AISI 316L preferred for sintered carbonation stones?

Enhanced Chemical Resistance
Because a carbonation stone consists of thousands of microscopic pores, it is highly susceptible to harboring bacteria if not cleaned properly. Breweries must use harsh caustic and acid CIP (Clean-In-Place) chemicals, often accompanied by boiling, to clear these pores. AISI 316L stainless steel offers vastly superior resistance to pitting and corrosion from these aggressive cleaning agents compared to standard 304, ensuring the stone lasts longer without degrading.

How should you properly clean a stainless steel carbonation stone?

Never Touch with Bare Hands: The natural oils from human skin can instantly clog the micro-pores. Always wear sanitary gloves when handling the stone.
Boil to Dislodge: Boil the stone in clean water for 15-20 minutes to expand the pores and dissolve trapped sugars and hop resins.
Blow Gas Through: While soaking in a brewery-approved sanitizer (like Star San) or during the final rinse, push CO2 or air through the stone. This forces the liquid and debris out of the pores from the inside out, ensuring it remains fully unclogged for the next batch.
