Take total control of your distillation with the PhilBilly Moonshine Double Mason Jar Thumper. Designed for the distiller who needs more volume and better flow than a standard single jar, this setup uses 3/4-inch copper pipe to ensure your vapor moves freely without the backpressure common in smaller 1/2-inch kits. Enhanced Flow and Dual Filtration By utilizing 3/4″ copper, this copper still attachment is built to handle higher heat and faster runs. The dual half-gallon jars allow for a two-stage process: use the first jar as a “thumper-flavoring” basket for fruits or spices, and the second jar for a final proof-boosting “slobber box” to ensure the cleanest possible spirit reaches your condenser. Professional Connection Options We offer this kit ready to mount with two of the most popular industry standards: 2″ Tri-Clamp (Tri-Clover) Ferrule: The perfect match for any standard keg still or modular copper column. 3/4″ Copper Union: For traditional threaded setups that require a rock-solid, leak-free connection. Custom Builds Available – Any Size, Any Fitting At PhilBilly Moonshine, we are distillers first. We know that every rig is unique. If you need this double thumper to fit a specific size or a different type of fitting (like 1.5″ tri-clamp, 1″ unions, or custom thread sizes), we can build it for you. Just contact us before ordering, and we will make sure your thumper arrives ready to plug-and-play with your specific setup.
