ProMaker Home Brewing Stainless Steel Diffusion Stone Inline oxygenation Aeration Aerator Kit Oxygenation Diffuser for Wort Chiller Kettle Pump Beer Brewing (Stone Kit)

The product arrived as pictured, although the carb stone was just chucked in with the other pieces, giving it blemishes, and reducing effectiveness. Not a big deal, but you might want to fix that in your packaging.

If you are using this to carbonate your beer you may have issues trying to find the right sized hoses and will need a liquid self priming pump but for about 20 bucks it is a great deal and works really well. Also make sure to clean it before and after with some Star San.

Easy to assemble and use

The thread on the hose barbs does not match the thread on the TEE. Could force it and Teflon tape it perhaps, but these are just mismatched parts, not a usable kit. Exactly what I was looking to avoid by buying a kit.

Unfortunately all the barbs are the wrong size! If you’re using a Corny keg the lines are 5/16 for gas and 1/4 or 3/16 for the beer line. There is no way to simply hook this up to do force carbonation for home brewing. Specifically the gas hookup for the carbonation stone is 1/4 in which does not fit a standard CO2 line.

The tee is threaded to standard pipe thread.Two out of the three fittings are pipe thread. The aerator fitting is straight thread and the shoulder is too small to seal with an o ring. Unusable.

had to had a ton of teflon pipe tape and tighten all the way to the hub to make a seal.

Build your own and save heaps! I can carbonate 19l a keg in about 1/2 hour by pumping cold un-carbonated beer out of a beer line disconnect (through a food grade mag pump), through the tee and injecting CO2 at 30 psi in through the carbonation stone and then returning the beer to the keg via a gas line disconnect, all under pressure. Leave keg in the fridge once done for 24hrs and its right to go! There is sufficient information online about how carbonation pumps work if you want to google and check out how it works to give you an idea how to build it, or buy a pre-built one, but with this stone and tee setup, I home built my own for a quarter of the price!!!! this cheap, you'll all agree it beats waiting 15 days for it to carbonate in the fridge, or wearing yourself out literally shaking your keg madly for an hour trying to force carbonate it!!!
