  Chiller Tubing Kit For Counterflow (+ $24.99)


The best deal we have ever found in a highly efficient counterflow chiller! This 25' pure copper pipe unit features 3/8" hose barbs for both wort and chilling water, and is an extremely efficient chiller, capable of chilling 5 gallon batches in one pass, as long as your cooling water is 60° F. or less. Easier to clean than a plate chiller, and much more efficient than an immersion chiller. This can be pump or gravity fed. 

Connection tubing and fittings are not included: use 3/8” inner diameter vinyl (our item E04, sold per foot) for the cooling water and 3/8” inner diameter silicone tubing (our item J46) for the wort inlets and outlets. As this is a counterflow chiller, be sure to connect the cooling water inlet to the same end as the cooled wort outlet. 9¾” diameter, 10” tall.

If you need parts to convert your Robobrew or Mash & Boil to a 3/8" outlet barb so this tubing will fit the outlet, order one each of parts L86 nut, L11 Silicone O ring, and L83 3/8" hose barb. This assembled threaded hose barb will fit both the outlet of the Mash & Boil valve, as well as the outlet and upper pump outlet of the Robobrew.

See item Q96 if you need a complete hose connection kit for most applications.

IMPORTANT NOTE: The outer cooling jacket is not designed to withstand high pressure, so do not connect this to your house water pressure without the outlet of the chiller being open.

Great product at a great price
For 22 years I’ve used an immersion chiller and I’m blown away at how much more efficient and quicker this counterflow chiller is.
Wort leaves the kettle and enters this chiller at around 200-210 degrees Fahrenheit and leaves this chiller at 54 degrees. It takes around 15 minutes to gravity feed out of the brew pot through the ball valve. With the old immersion chiller I would usually loose patience after 20 minutes of chilling and dump the wort into the fermentor at around 80 degrees which is to warm. The cooling is painstakingly slow from 100 down to 70 with an immersion chiller but not with this counterflow ! It all happens in one pass through.

Good Chiller!
I was a little spoiled by my old 50' chiller as I had to slow down the wort flow through this 25' model to cool properly. Get the Q96 tubing kit and you'll be brewing immediately. Remember to sanitize before use and blow out the water if you're storing it in an unheated area in winter.

Counter flow review
First time I've ever used a counter flow, AWESOME!!! The flow thru thermometer showed 70 degrees into the keg. So much faster and easier than immersion chiller.

Counterflow Wort Chiller
First, if you are using a garden hose from an exterior hose bib, put a flow restrictor in front of the cold water in, so you don't rupture side wall of the chiller like I did. Williams stood behind the product so it really wasn't a big deal, just an inconvenience to me. Even with the chiller sidewall blown out, this chiller chilled my wort to yeast pitching temperature in less than 30 minutes. Works perfectly and efficiently, on my next batch I'm going to attempt to run the child wort directly to my fermenter instead of back into my brew kettle. I believe that one pass through will bring a boiling wort to less the 70 degrees, of course, that would depend on the temperature of your cold water.

Chiller works great
Have only brewed one batch so far but this brought my wort from 200 degrees to 76 in about 15 minutes.  I had to rig up some stainless steel compression fittings, ball valve and in line thermometer to make it more convenient to use. Welds look good and no leaking.

What is the easiest way to start a gravity flow siphon?
Either by sucking on the end to fill it, or to prefil it with water and then release the water with your thumb over the end when it is low enough.

Will the difference in hose ID cause major leaking problems if I connect to 1/2" Barb cam lock fittings to use with my pump?
It might, unless you can figure out a way to close the gap between 3/8 and 1/2"

Would it be possible to sanitize by submerging the entire product in hot water, or is the sidewall material not very heat tolerant? Thanks.
To sanitize, it is best to run sanitizer through the copper wort tube. Soaking the entire unit would not move the sanitizer through the tubing well enough to sanitize in our opinion. The outer plastic hose cannot handle temperatures of over 150 degrees F.

How much pressure can the outer jacket handle? The warning concerns me. Thanks!
It can handle water flowing through the outer jacket, but it cannot handle house water pressure. If you do not restrict the output of the cooling water, you should be fine.
