3-Lead free water soluble flux. 6-patience & a steady hand. You shouldn't have any trouble putting it together using the pictures as a guide.
It is pretty much self-explanatory by the pictures. You can also message me and I'll be happy to assist. Always clean BEFORE & AFTER each use. Wash with hot water, a mild detergent, rinse well, and dry with a soft cloth to prevent spotting.
The inlet tube is 1/2" and the outlet tube where your hydrometer goes is 3/4". Each have a 1-1/4" reducer on top and the outlet side has a 1/2" discharge spout and the base is 3.This device will greatly improve your cuts, you won't be disappointed. If you're not into soldering and you want one that's already complete, message me, if I don't currently have one listed I will build one for you and let you know when it's listed. It usually takes me a couple of days to complete one in between my other chores. This item is in the category "Home & Garden\Kitchen, Dining & Bar\Brewing, Distilling & Wine Making\Equipment".
