Citric Acid Co2 Needle Valve by Nolibert
by Thingiverse
Last crawled date: 3 years, 1 month ago
This is a DIY needle valve for people using citric acid for co2 infusion. My needle valve broke, this solution works but as you can see on the pictures should only be used as a emergency solution until you get a new co2 kit as it puts stress on the co2 line itself. For now it works, i will wait and see how long this will run on my setup and report back. I have no detailed part list since i put this together with stuff i had lying around. Nuts used have a 6mm diameter, the bolt should fit the nuts and should be at least 4cm long. i put some big threaded washers at the start and the end to make it more usable and to get a bigger area of contact to the co2 line.
