I need some parts for my co2 system, to make it more co2-leak-proof.
Anybody got good websites to download such parts from?

Download parts from?? Do you have one of those nifty Star Trek replicators?? :P Just kidding.

What kind of CO2 system? DIY or pressurized? What exactly do you need? I will assume you have a pressurized system, what kind of regulator, needle valve/metering valve, bubble counter, tubing, reactor and whatnot? Where are you having leaks? Have you tested for leaks yet?

rotf..that's what happens when you try to think about 50 things at once.

Anyway..it's a preasurized system. I don't know exactly what parts yet, but I was just wondering if anybody knew of anygood places.

I know it has leaks because the co2 drains in a month. I don't know exactly where, but I am assuming that if I "rewire" it like I should have the first time but didn't because i'm lazy, then it will work.

Well, how do you have it setup right now? You should check for leaks with soapy solution or windex or something. Once you find out what you need then we can help more. If it is simple connectors then you should be able to get what you need from grainger (www.grainger.com).

First make sure all connections are tight. Second get a new washer for the regulator-cylinder connection. This washer should be replaced every time you fill the cylinder. For all connections after that I use pipe dope. I will not use teflon tape on a pressurized gas system. I don't want little pieces of teflon tape clogging my needle valves or other parts. A thin layer of teflon tape and making sure all connections are tight will go a long ways toward sealing the system. And as Jon said checking the fittings with soapy water will tell you where the leaks are.

I had a leak when I set up my first system. Turned out to be the crumby washer that shipped with my Aqua Medic regulator. I replaced it with a normal washer and everything's been fine since. Dunno what they were thinking when they bundled this sorry excuse for a washer. All it was was a squared off o-ring that promptly disintegrated when I tightened the connection.

Some of the washers will compress after you tighten them, and then cause a small leak of CO2. You should re-torque the tank connection after about a week of use.
