Built from Bobby M's tutorial. All sweated joints. Cam lock fitting in picture is not included. There is a water hose connection on the water in part, a 1/2" female thread on the wort in and a 3/8" female on the out. These tend to go for $70 new online. I'm thinking $50 used. Make an offer. It works great. I'm just building a new rig and looking at plate chillers for compactness.
