Carbonation Stone 150mm x 1/4" Threads (0.22 Micron)

Force carbonate your beer, cider, or sparkling water faster and more efficiently with this professional-grade 150mm Carbonation Stone. The ultra-fine 0.22 micron pore size produces thousands of tiny CO₂ micro-bubbles that dissolve into your liquid rapidly — dramatically reducing carbonation time compared to standard methods.

Typically found on brite beer fermentation tanks, carbonation stones are designed to be directly mounted — ideally at the lowest point of the vessel, giving CO₂ the longest possible distance to travel upward through the liquid for maximum absorption.

With a G 1/4" NPT male gas inlet, this stone is a great tool for home brewers and bar setups alike. Made from high-quality stainless steel — food-grade, non-toxic, durable, and easy to clean.

Tips for Best Results

• Keep your liquid as cold as possible — CO₂ absorbs more readily at lower temperatures
• Mount at the lowest point of your vessel for maximum CO₂ travel distance
• Carbonate at serving pressure (around 10–14 PSI) for a controlled, consistent result
• Always clean and sanitise the stone thoroughly before and after each use
• Soak periodically in a cleaning solution to maintain flow rate through the pores
