I did a little research last night on the internet about how other people where building their CO2 reactors. Nothing like researching after the fact, right? I was looking to see if anybody else was building their reactor the same way I was. I didn’t find reference to it, but, there are hundreds of DIY Reactors out there, so I not too worried about not finding one. I did stumble across a person who used an RC airplane part called a Bulkhead Fitting. This looked to be a much cleaner way of attaching the airline tubing to my reactor.
Big Al’s was having it’s 1 year anniversary this weekend, and the “plant guy” was giving a demonstration on how to build a proper planted tank. I figured I wouldn’t learn much, but it was something to do with my Saterday, so I went. I was right, his song and dance was for new peeps, and not experienced planted tank creators. More importantly, there is a hobby shop next to Big Al’s, so I could pick up this part.
At the hobby store, in the RC airplane section, I found my new fitting. It is a “Large Bulkhead Fitting, 1/8 inch I.D.” packaged by a company called “Fourmost Products”. It is designed to be used as a fuel line connector.
These modifications replace the previous steps I have posted to my blog.
Here is my old (heh, 2 whole days!) airline connection using a airline tube elbow fitting. I had zip-tied it together. I had managed to make the whole reactor without any glue, and it didn’t leak (much)!
Here is the top part of my new fitting. I think this looks much better then the old fitting did. I used the old part of the hose that had the old fitting cut into it to make a seal for my new fitting. I don’t have any small O-rings for this yet, so I had to improvise. Getting proper O-Rings is on my todo list.
Here is the inside view of my new fitting. Don’t do what I did, and make the hole too close to the outside of the endcap so the nut won’t set square. I still put it together like this because I am way to impatient to go get some silicone, and seal the hole up, and drill a new one. My fitting does leak just a tiny little bit, but not enough to worry about it today.
