I know some of you have the same problems as me, over time, your siliconed tubing comes loose under pressure if you are using a glass diffuser. Instead of resiliconing the tubes every few weeks or pouring glue on, for $5, you can have this presumably leak free. This is my attempt to stop leaks for good.
Note-I have just done this, i will post any issues if they arise
To have a leak free DIY co2 system for a MUCH longer period of time compared to the tutorials out there
-3/16 Compression Fitting with barb (add 2 more if you have a separator)
-Nuts if not included
-3/16 drill bit
-Wrenches to tighten nuts
This is what you basically need, just giving a visual. You don't need washers, i was going to use them but they really arn't needed.
Step Two-Drill 3/16 in hole
Just like every other tutorial drill a hole. This needs to match the size of the compression fittings
Step Three-Silicone Fittings and Cap
I don't even think this is necessary except to keep the nut from backing out. Gives extra protection from leaks. Blow on the fitting to get any silicone out of the fitting's air flow.
Step Four-Tighten Fittings
This is simply taking your wrenches and tightening it all up. Nothing challenging here, just make sure they are tight. I forgot to take a pick of the red cap, here is my seperator cap
Step Five-Attach Hoses
Put your silicone tubing over the barbs. I used silicone here again. Definitely not needed. However, because the barbs are bigger than the tubing, it lubricates them and makes them much easier to put on. So, even though over kill, it makes it easier.
Step Six-Throw your silicone engulfed original reactor away.
Like i said, i have not had a chance to see how long it will last. But it is so much sturdier than other tutorials. I'm sure i'm not the first to do this but it's easy and costs under $5, assuming you have tubing (you can use your old stuff if you want) and tools. It is much nicer and if it does leak, it will be much easier to fit. The fittings can be moved to new bottles in the future as well if a cap fails.
Hope this helps some people.
