2" Copper Coil Condenser causing a knocking or 'thumping'This handmade, double helix condenser coil is 100% copper. Distillers often use these coils as part of a Liquid Management (Bokabob) column. The end cap lip will snugly fit a 2" ferrule, and the outer diameter of the coil is compatible with insertion into a sight glass, as shown. Important note: If used in a closed system (such as a liquid management column), ensure a hole is drilled in the top of the end cap to prevent any buildup of pressure.
