1/4" O.D. Copper Coil - Fits inside 2" copper pipe.

Coil length is 6 inches

This is all you need for a 2" still. Anything larger is just overkill. To see this condenser run in our stills, watch our 2" liquid management video on the videos page. This is the same condenser used on that still and it can condense up to 3 gallons per hour.
