Shoot him a PM yourself or I can ask him. He purchased my setup sometime last year, at that time I didn't provide any Co2 tubing.

Guess I wasn’t clear. I didn’t blow the tubing off (if only!), I BLEW UP the glass diffuser. As in shattered into pieces. As in broke it. The needle value wouldn’t move at all, and when it did so much gas rushed through it just broke the diffuser into pieces inside the tank (yeah that was fun to clean up).

I just want to know if it’s ok to add a dollop of lube or if I should get another, different needle valve?

Well I definitely know it is working well.

Came home to find all my fish at the surface and my WCM huddled together. So I shut off the CO2 and did a water change (been a while since I did one anyways). Also adding a small airstone.

Anyone successfully just using a hose barb instead of compression nut after the needle valve? The watts compression nut is just giving me a hard time and no tubing is fitting on it properly, not even the watts tubing from HD.

I just had to use a wrench and REALLY close the nut (otherwise, yeah, the tubing wasn't getting caught). And if there's one think I can tell you, it's that my tubing is secure, LOL!

The tubing is too thick, the nut wont fit over it to even be able to screw it on. I may try tygon tubing but I'm still deciding on what size I need.

If I use a barb for 1/8 ID tubing, what size barb should I use? Also home depot doesn't sell a barb that fits into the 1/8 size threads we are using, the smallest is 1/4. Would there be any issue if I used a reducer fitting to go from 1/8 up to 1/4 thread size and then from there screw in the 1/4 threaded barb? Does going up in size affect pressure in anyway or no matter what size your fittings are, the pressure is all about how much co2 is being pumped through it?

Out of curiousity, what is the working pressure we are working with, with the paintball setup we are using? Would it be pretty much considered the full pressure of the co2 tank since there is no regulator like the full size co2 setups to lower the working pressure?

That is exactly what I have set up and it is working without any problems. I actually have a 1/8" barb attached to flexible PVC airline tubing (Lees stealth tubing). I can take a picture when I get home and show you my setup if you like.

A pic is always appreciated. I found a 3/16 barb x 1/8 male NPT on ebay so I may use that with some Tygon 1/8 ID tubing. Sounds like it will work. But yes, the pic will still be cool. I would like to see a pic of someone else's barb setup!

I'm swapping out the needle value for one of the larger Swaglocks for sale in the SnS. Does anyone know if I can add in a solenoid like this one. Or does anyone have a recommendation for one?

I have a 24 oz paintball tank, 32 degrees on/off ASA, stainless steel Swagelok needle valve (SS-OVM2-BKB), 1/8" to 1/4" reducer, then a 1/8" hose barb. Waiting for a gauge I ordered to put in the second 1/8" NPT on the ASA.

Very cool! Thanks for sharing that. Btw, what size tubing is that and what mind may I ask?

It is your standard airline tubing, which is 1/8" inside diameter. That particular tubing is Lees stealth airline tubing, made of flexible PVC and bought at petco.

Sorry to hijack, but that lee's stealth tubing will collapse if there is any sort of vacuum in your lines. use their elite tubing. it's clear green and also made of pvc.

So, I thought my setup was awesome. I got it "right" on the first try. Made sure to teflon tape everything, tighten everything, and tested it in a bucket of water - NO leaks.

However, my first bottle emptied out in about a month. My current bottle is down to 200psi level after 2 weeks.

I did almost gas my fish twice in the last two weeks, by setting the bps to about 5-6 for 24 hours each time. But, would 48 hours of 6bps empty half the tank? The rest of the time my rate is about 1-2 bps.

I re-tested the connections again under water, and everything is solid! No leaks. The only thing I can blame now is the tubing, which I haven't tested. But, maybe it's normal to use this much, or no?
