4 Inch CapLogic Upgrade for 6 to 25 Gallon Copper Stills

The 4 inch CapLogic is a copper cap upgrade designed to fit a wide range of boilers, from 6 all the way up to 25 gallons. It opens up the top of your still to a larger 4 inch port, giving you easier access for cleaning, loading and adding column hardware.

Because it is copper like the rest of your still, it keeps the vapor in contact with the metal that removes sulfur and sharpens flavor, rather than introducing a different material into the path.

For a hobbyist looking to get more versatility out of an existing rig, this cap is an affordable way to expand what your still can do without buying a whole new unit.
