Bulkheads for standard airline tubing

Jake_the_reefer · Dec 9, 2019

So I am planning on making some nice dosing containers out of water bottles and I want to drill the top and connect the airline tubing to the top so it can be disconnected as needed. To do so I am thinking I need a small bulkhead if sorts to secure an air tight seal on the tubing. Is there such a thing for air tubing?

John guest fittings with ridgid air line as a pick up in the bottle. 1/4" most likely.

So a standard john guest fitting should hold airline tubing? Think home depot sells them?

Yep. I just looked to get some for my dosing container. $5 a piece I think. BRS sells the ridgid for $3 for 16"

Y wouldnt you use RO tubing.

So dont have to worry about the line kinking of the inside i used acrylic piping inside the containers.
This is a little smaller than airline tubing and did not want to attach to the bottom of the bulkhead. So cut pieces of silicone airline tubing, heated and sliped over one end of the acrylic pipe. This made a snug fit.

still working on my controller cabinet so forgive the half finished look.

I installed the mur-lok bulkhead from brs with clear acrylic rod inside the container. The rodi polyethylene tubing works great in the mur-lok, but it won't connect to the doser pump adapter. How did you get your's to fit?
