What @Elfmaze said is pretty right on. The glycol ports are 1/4" Female NPT so you could do quick disconnects or just a 1/4" Male NPT x barb will work.What connectors do you recommend to the input and output for the glycol lines? Looking at insulated lines and trying to figure out best way to connect hem to the conical fermenter and also the glycol chiller. I have my 15 gallon jacketed conical on order and planning out all the other components!
