I have a Duda Diesel 40 plate chiller for sale. I used it twice, and it worked great- only selling it because I'm putting brewing aside for awhile. I attached four stainless steel 1/2" male NPT thread nipples to the inlets and outlets. I think these chillers sell for 100 bucks on Ebay and the fittings were 4 bucks each. I am asking 90 bucks. Thanks!
