This kit will convert all 10 gallon Igloo®, Rubbermaid®, and Gott® round water coolers into an insulated mash tun. Everything is included, the stainless false bottom, valve, connecting barbs, silicone seals, and tubing.

This includes our new more efficient false bottom with a wort pickup pipe that is held ¼" from the floor of the cooler for maximum efficiency, and a silicone lip for the false bottom to both securely seal it to the cooler bottom and prevent cooler scratches.

Just remove the valve from your existing 10 gallon cooler, and install the bulkhead and valve, and the inside false bottom and hose attachment.  Includes a 3/8" outlet hose barb.

As of August 10th, 2018, we have updated this to include a longer bulkhead, so the valve handle does not have a problem closing against the cooler.

I can't get the gasket to stay on the strainer disk.

Does exactly what it says it does.  After attempting to make a manifold system on an old cooler, I switched to this.  Best decision.  The only issue is that the valve drips.  I am still VERY happy with this and will probably get another.

False Bottom
Great product and great price.  I would have given it a five but for two minor issues.  First the rubber gasket that fits around the false bottom itself isn't as secure as it could be.  No issue when the bottom is in place but a bit of an annoyance when your cleaning it or it's not installed.  It comes off easily and takes some getting used to to ire-nstall.  Seems like a better design would have been rounding/smoothing the edge of the bottom eliminating the need for the rubber gasket or permanently attaching the gasket (becoming a sanitization concern, I guess).  Second minor annoyance was the valve itself.  I attached it to my 10gal Lowe's igloo and the valve handle hits the recessed edge of the cooler.  Turns out I was able to address the concern by tightening down the valve handle.but I had to figure that on my own.
     Overall though it was a great conversion kit!

Good concept, bad product.
The kettle valve does not protrude far enough from the new 10gal igloo sidewalk to fully close the valve. Glad I finally have a false bottom; disappointed I have to get a different bulkhead in order to use the supplied valve. 1 star for usability, otherwise would have rated higher. Shipping was prompt. 

William's Brewing Responds: This kit has worked with all the Igloo and Rubbermaid 10 gallon round water coolers we have tried. Perhaps your 'igloo sidewalk' is a bit different?  Please contact us at 800-759-6025 or service@williamsbrewing.com and we can figure this out.

#j78 10 gal conversion for mash
I agree the silicone seal needs some revision. Hard to keep on until in place.i might suggest a wider silicone band..I would pay for that!
I've been using Charlie P.s zap pap since 1993. So I think this is the best priced easiest thing to use ever. Frugal is my middle name. This is the best price out there!! Thank you for carrying such a quality product. Next on my list is a better brew pot.

Are all the valve components and fittings 100% stainless steel?
All are except the collar of the nut which holds the inner hose nipple for the bulkhead. This nut is nickel plated brass (FDA approved).

Will this work with the 10 gal igloo coolers from Lowes?
We have not tried this, but based on the fact that this looks very similar to 10 gallon Igloo coolers we have tested, it will work.
