Its quite simple, just a piece of 3 inch diameter pipe ~10 inches long with a piece of stainless with holes drilled at one end inside the pipe. It will take ~3 hop plugs.
On each end of the pipe is a bit of flat stainless with a hose barb and it all bolts together. Nothing high tech thats for sure...
I put it after my real brewer h34r: march pump, and go into the hopback then straight to the CF chiller.
