Thanks for the info, looks like a great idea and I think I'll go with these fittings. Just trying to think of whether I want to put the fitting close to the chiller or the fermenter...any suggestions or photos of how you did yours?
I put mine at the fermenter. This allows me to disconnect and roll my fermenters either to the garage on brew day to fill or outside on the driveway to clean. During fermentation I have them in a utility room in my basement. I used silicon tubing and basically have just enough to clamp the tubing to the coil and the other end to the fitting.
Something that is shown in previous pictures in this thread is insulation. I ran my first ferments without insulation (I was excited and in a hurry) and was amazed at the amount of condensation on the tubing. I would have thought the silicon would have had a slight amount of insulation properties. I now have piping insulation bought from Lowes and that problem has been solved.
