Help with C02 Canister Regulation

Hello,

I am building a simple pneumatic system which is powered by disposable 16g CO2 canisters. I'm continuously blowing either tubing or my ptc fittings, all of which are 1/8"npt->1/4" tube from Pneumadyne.
From what I have read, when you puncture one of these things it unloads at >800psi.

Would you recommend I beef up my tubing/fittings? If so, please provide links.

Or, should I figure out how to regulate the flow coming directly out of the canister? Again, please provide links.
I have tried 3 different pierce CO2 adapters/"regulators", but even with a tiny turn of the valve I am getting blowouts.

Thanks for any input!

What peak pressure is the system operating at?

From what I gather, the CO2 cartridges put out around 850psi when they're first punctured.

OK, but what is your desired/required operating pressure for your system operation?

Hard to say what is optimal since I haven't tested the new design, but the system tops out at 200psi. I'm running a standard compact cylinder off 16g CO2 canisters, using a standard 3-way switch from Pneumadyne. My guess is that I want to be in the 100-150 psi range.

Here is the regulator I am considering buying... just wish there was a cheaper/simpler option.

Cheers,

Whatever verified peak pressure that your system operates at you should select and design all system components to operate at a pressure not less than 1.5 x greater. The factor of safety is to protect you and other operators as well as ensure system dependability.

Thanks for that, makes sense. However, this is just a personal project, and I know there are many other products out there that use CO2 canisters and don't operate at 500psi.

If you have suggestions for a different portable/reusable gas supply I would like to hear it, or if you can think of a better regulator option.

There is very little gas volume in these small cylinders (approx 120 cu in at 150 psi). Are your sure that will be sufficient to operate your system for the operating time you want/need?

Yes, I'm sure, thanks.

Really just here for potential alternatives to this regulator:

Cheaper or smaller, or both.
