Resource What tube do I need? Helium

[Podlerman]

I have helium. Apparently I've been told "that cylinder is designed for a nylon balloon-filler fitting. It won't take any gas regulator fitting, such as CGA 580. Doubt you'll get an adaptor that's made to go between that type of cylinder and a gas regulator." by a previous commentor here. So I'm dropping the regulator idea and just thinking of using two helium canisters, and just to put two tubes (somehow manage to support the pressure and not fall out), and put it in the exit bag.

I can't waste hundreds of euros on a dozen different plastic tubes, so which size is best for this? 1/8" good enough? I think 1/4" is too big, imo.

Whatever size fits snugly and fits over the value outlet. Secure them with the proper sized hose clamps. You'll probably want to put a "tee" fitting in the line to connect both tanks to one hose,also secured with hose clamps. Hopefully that helps.

I was posting about Fentanyl patches in a different post, and I mentioned a guidebook on ctb that I came across, called 'Guide to a Humane Self-chosen Death', that discussed fentanyl. But it also mentioned the method you're using with the helium party balloon stuff. I just said I'd link it here, because the guy talks about what tubes to use, and it shows pictures of how to put on the bag etc.

The link is here if you want to check it out:

Btw, do you know how long the gas lasts for? Is it just guesswork?
