NPT SS316 Brewing Accessories Carbonation Stone With Tri Clamp Connection

Carbonation Stone Brewing Accessories | Tri Clamp 1.5 in. x 4 in. x 1/4 in. NPT - SS316

Carbonation stones, typically an accessory found on brite beer fermentation tanks, are designed to be directly mounted via a Tri Clamp fitting. Each carbonation stone, made from sintered stainless steel SS316, is a submersible porous body that diffuses CO2 gas directly into brewing liquid. In an ideal system, the stone is mounted on the lowest part of the brite tank providing for the longest distance for CO2 to travel to the head. Some brewers use a carbonating stone inside a conical fermenter (or Uni Tank), rather than a brite tank. The most efficient system on the market for carbonation.

Specifications

Some people like to speed up the process of force carbonating beer by putting extra high pressure on the keg, but a more effective and precise practice is to use a carbonation or diffusion stone.

Rocking your keg with the low pressure gauge set at 30 PSI may get the beer carbonated in one day. This may also, however, cause you to end up with over carbonated beer, which can be a hassle. It can take longer to get the carbonation out of solution than it look to force it in.

A better solution for speeding up carbonation would be to use a Carbonating Stone, also known as a diffusion stone. This is a piece of stainless steel, perforated throughout with a huge number 0.5 – 2 micron holes. Keg lids fitted with a diffusion stone are also available.

How to Use the Diffusion Stone

• The “Stone” sits inside the keg near the bottom.
• A hose barb attaches it to a length of tubing (generally about 2 feet of 1/4” ID thick wall vinyl hose) which is affixed to the short downtube under the “in” or “gas side” post.
• When the CO2 is connected, it sends a tremendous number of gas bubbles out through the beer. The miniscule bubbles create a huge amount of surface area to help absorb CO2 rapidly into the beer. This is actually a miniature version of a device used by commercial breweries everywhere.
• Carbonation should be virtually instantaneous, though the manufacturer recommends carbonating your beer at least a few hours before serving.
