or reflux condenser) is a device arranged for the partial condensation of a vapor stream

Cooling ports are 1/2" NPT fittings

Inside there are (4) 1/2" copper tubes

there is no risk of pooling condensate as found in the spiraling tubes of the 'worm'

2" Copper Coil Condenser or reflux condenser) is aThis 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.
