Q: I have the Grainfather and want to covert to the camlock fittings. I would like to buy the three fittings to convert the circulation pipe and counter flow and also buy the Robobrew Recirculation arm so I don't have to cut the arm I have. Would you sell the parts that way? Can you let me know when the parts will be available? Thank you John Watzke
A: The Robobrew Recirculation arm has different dimensions than the Grainfather arm, and will not line up perfectly with the hole in the glass lid if you just add cam locks and clamp on the Robobrew arm. As far as parts, we should have these in late August or early September.

Q: Will this fit on the Grainfather (modified for a camlock fitting)?
A: Yes, although we do not yet have Camlock fittings in stock with the correct BSG thread so you can adapt your Grainfather. We should have these fittings by early July.

Upgrade to Brewers Edge Mash & Boil
Not much to say about the arm except that is very well mase and at a decent price. I used it to convert my Mash & Boil recirc arm to a cam lock attachment. I had to buy a female cam lock connector and attach it where the original arm attached. I have tested it out and everything work great.
