DIY NoPox Doser

[andyg1960]

Made my NoPox bottle into its own dosing dispenser. Rigid plastic tubing on the inside, John Guest type bulkhead fitting and one way valve on the outside. Kinda cool.

I must admit, that is pretty. I make my own DIY NOPOX and went ghetto with the container by simply using the Vodka bottle. I might look into putting a John Guest (JG) on the cap, but first I'd like to know what you did on the bottle side of the JG? Does the tubing completely pass through the JG, or is there another piece of tubing connected to the back side of the JG? One last one, do you have the part number for the JG you used?

EDIT TO ADD: Oops, just re-read the OP and saw that you used rigid tubing on the inside.....good stuff!

Here is a link to the bulkhead fitting i used for the top:

1/4" rigid tubing on the inside. Couple of photos attached. I got the idea from a brs video, so if you google brs diy dosing container, you will see what i stole, i mean used.

Is this the rigid tubing you used?

Also, do you replace the airline tubing over time?
Also, why did you use a check valve?
Super cool idea!

Interesting - I'm also looking at this. I have a Voss water bottle that I was going to use. I bought some acrylic tubing but I hear you are not supposed to use acrylic with the nopox stuff. So looking at tubing for the dosing line and what to use inside the bottle to reach the bottom. With regards to the valve on the outside what is that? Couldn't you drill in a tiny 1/16 or so hole or does it evaporate fast.
