Convert the Recirculation Arm and the Counter Flow Chiller of the Grainfather to convenient Cam Lock fittings. This kit consists of 5 BSP thread 304 grade stainless parts to convert a Grainfather Recirculation Arm and Wort Chiller to easy to use Cam Lock Fittings. We also include new silicone chiller input tubing for the Grainfather Counter Flow Chiller, as the existing tubing can become stiff and make it hard to insert the new cam lock fitting.

Super Easy to Convert!
I read some reviews regarding this conversion and they were not all positive. I had no problem converting my Grainfather to the Cam Lock's. It took me less than 20 minutes. If you have any issues installing the new hose, simple use a very small amount of keg lube. Happy Brewing!

Game Changer
I was on the waiting list for this conversion kit for about six months.

Worth every second. :) 

If you're even slightly handy you can fix one of the worst design flaws of the grainfather. Should have be camlocks all along.

As many have commented the barb for the counterflow is too large. I wanted it to 90 into the tubing so I bought a SS barb 90 and a female threaded cam lock. It was completely worth it. I love the setup. Each new improvement makes the system feel more like mine.

A robobrew false bottom has also been absolutely worth it. Fits perfectly, and solve issue of me knocking off the bazooka filter on the pump.

Next step is figuring out how to put a handle on the lid. I'm sure the next generation of grainfather will fix all these issues, but the system is so much better than my old propane system. Brewing indoors is such a game changer. :)

Love the change!
After a frustrating period of time and a machine shop too, to get the compression fitting onto the cut recirculating pipe.  But when I did, it has now changed my entire brew day.  I was consistently getting stuck mash in my Grainfather.  With this kit, it allows for more wort to flow faster through the grain bed.  I had a very successful brew day with no complications and I owe it all to this Cam Lock Kit. Thanks Williams Brewing!

Grandfather cam lock conversion kit
Really appreciated finding all the parts for this conversion together in one kit.  i have installed it but not actually tried it.  Installation was easy other than the need to hacksaw the previous screw connector off the mash feed pipe.  Seems like it should be an improvement.

Works well. A little difficult to complete
I will start off by saying that the cam locks really do make the brew day easier. I’ve tried it on 2 brews and it works very nicely. I would give the kit a 5 except for one point. The connection of the new hot wort-in tubing to the chiller is a bit difficult due to it being much larger in diameter than the original tube. It was a bit of a struggle to get it on and secured with a hose clamp but I was able to do it without any leaks. Overall I’m very pleased with the quality of the parts and the new ease of use of the Grainfather.

Hello, I was wondering if you have corrected the common problem in your reviews that the hose and fitting to the CFC do not fit?
No,the conversion kit we sell is based on the wider Counter Flow Chiller Tubing which is on most of the Grainfathers. If you have 3/8" inner diameter tubing on your Counter Flow, this part does not fit.

What version of the Robobrew V3 recirculation arm can be used instead of cutting the Grainfathers recirculation arm?
Any Robobrew Gen 3 arm can be used, because they already have a cam lock fitting. Robobrew Gen 2 arms do not have a cam lock fitting, and cannot be used.

Can you include an option for a second cam lock barb so that I can connect one to outlet pipe of the counterflow wort chiller. This would facilitate connecting it in reverse for cleaning.
You probably need our part #L74 which is sold separately.

Will this work on Robobrew v2.0?
No, the Robobrew has a slightly thicker recirculation arm.
