This Copper Thumper/Doubler 1/2 gallon kit is the perfect addition to most smaller stills. The advantages of a thumper would be gaining a higher proof on the first run and/or to add back flavor that is lost during the first distillation process from the pot.
Copper 1/2" piping with a 90 degree elbow to prevent bottom blowouts caused by hot spots.
20 oz Revere copper and silver based, lead-free solder
JAR and BAND NOT INCLUDED.
