How hard is it to install a solder-on sealing cap kit?
The hardest joint, copper to stainless, is already done when the kit reaches you. What's left is fitting it to your existing still, which is about as simple as soldering gets. Use lead-free solder and take your time, because a clean joint pays off on every run. If you aren't sure the cap suits your still, ask us before you start.

A reliable cap is one less thing to worry about, so you can focus on heat and cuts. It's a sensible upgrade whether your still makes distilled water, essential oils, fuel alcohol, or spirits under federal (TTB) permits. Free U.S. shipping comes with the kit.
