Description

New! Easier to Sanitize Design
This innovative design was the result of customer feedback about the difficulty of santizing our traditional barbed stone when tubing was attached. We added threads instead of a barb and now you can use the fittings you see at the bottom of this page to connect and disconnect your tubing. This allows you to place the stone by itself directly in a pot of boiling water to sanitize. Easy.

316 Stainless
1/2" diameter. Stone is 1" in length. Overall length is 1 7/8"


To Sanitize
To properly sanitize your stones, we recommend you run it in a sanitized solution for 5 minutes. If the stone becomes clogged we recommend boiling the stone for 1-3 minutes to help break down anything within it.

Important Notes
You do not want to touch the stainless stone portion with your hands. The oils on your fingers can actually clog the small pores in the stone.

The stone does not come with the barb fitting or flare nut - those will have to be purchased on their own. See the Related Items below.

The 2 Micron size is more commonly used for aeration or oxygenation pre fermentation, but can be used to carbonate beer. If you wish to use an aquarium style Aeration Pump to pump air through this stone we recommend a "deep water" type for aquariums, as these will have the necessary PSI to force the air through the stone and into the wort. If you are looking for a ready to use package check out Complete Aeration System. Thank You!

I liked the thread. However to really complete the set up they should also sell a 24" tube to match up with this.

To aerate my wort. The 0.5 clogs up too much, so I'm switching to 2 micron

Test yours before using!
I let my old aeration stone grow mold (my fault). I purchased a new one and air leaks where the stone is attached to the flare threads. No air actually makes it through the stone. Morebeer was great and sent a free replacement. Last week I got my third free replacement and all three of them leak and are totally worthless. I commend morebeer for their customer service, they sent free replacements quickly and with zero hassle, but the product itself is flawed. I'm not sure if it's the current batch that has a manufacturing defect or what, but all three have just ended up in the trash.

Now I'm stuck with an aeration system without an aeration stone.

Perhaps you realize this and the product is truly defective, but for the benefit of others who may not know...

With these metal-to-metal flare connections you're supposed to use a nylon washer (Morebeer part KEG602). The connection will leak air without one.

(Plastic ball lock fittings like KEG730 are an exception to this rule, because there's a bit of plastic incorporated into the end of the fitting itself.)

Great way to oxygenate wort!
This stone works great. I turn on pure O2 for 30-60 seconds into the wort right before I pitch yeast. Has been working great for me. Clean it by boiling in water for about 10 minutes.

Works great if you take care of it
I've owned two of these to use with my oxygenation system and if you take care of them, they'll work great.

I boil my stones to sanitize and remove any wort that may be trapped. If you don't boil them and leave them wet, they can grow mold. So make sure to let them air-dry after boiling.

But don't heat them dry! This will break down the glue that holds the stone to the MFL fitting cause it fall off. This happened to my first one.

Awesome
They are made of very high quality. Definitely worth the money. The threaded end makes them simple to sanitize.
