CO2 Cartridge - Best ways to use?

I had a flat the other day, and had NO idea how to get my CO2 canister started. I kind of screwed it onto the tire, then unscrewed it a little, and it seemed to do the trick, but I'm still not sure how one gets it to eject air.

Also, would be helpful if there's a way to only let out PART of the canister - for example, if youre looking for the hole to patch on your inner tube.

Anyone know how to do this?

Any inflator I ever used could control the amount of CO2 you released. The one I have kind of works like a garden hose nozzle, the more you twist it, the more CO2 will be released

I've got a question about the reuse. Can you reuse a half empty CO2 cartridge thats been sitting in the holder? I had a low tire and no pump on me, so I had to use CO2 system and only used 1/2 of the cartridge. Its been sitting in my bag for about a week, can I still use the other 1/2? Is it bad on seals to keep a 1/2 full cartridge opened inside the inflator?

I've got this inflator and actually recommend it to anyone. Its very easy to use, to control, and secure on the valve. Most importantly for me, it takes all 12g & 16g, threaded or non-threaded cartridges.

it's been said elsewhere-- but you should get a pump... youwill run out of CO2 if you have a slow leak that needs constant filling, and the 'reuse' feature doesn't always work... If you are in a race (triathlon for example) where you have to do your own repairs and time is an issue, CO2 works great. Any other time, a pump is your friend. It never runs out of air. There are frame pumps that fit nicely into any bike frame or mini pumps (I hate these-- you need about 150 pumps to get a tire full) that fit on your water bottle cage or in your pocket.

[off topic] Did you know that those CO2 pumps make great fire extiquishers? I used to keep on in my car, but then I realized a new car was cheaper than CO2 [/off topic]

I prefer the mini pump, for as often as I use it. Just be sure to get a double action one.

If you leave a half-empty pump alone for any length of time, it will evacuate itself.

I have a similar inflator that doubles as a mini-pump. I wouldn't rely on it as a pump for any serious riding but it's handy for priming the tube and for dire emergencies. I like CO2 and now that I've tried the Topeak Road Morph pump as a travel pump (CO2 doesn't fly on airplanes!) I wouldn't want any other pump again, as it's really a superior pump. So CO2 at/near home and Road Morph when travelling is what I'll continue to use. I suppose if I were riding a really long brevet I'd consider taking the Road Morph for that (who wants to be out of CO2 in the middle of nowhere at 1AM?).

Anyhow, for the OP's question: get yourself a trigger inflator! Better still get the combo inflator I use and you can use the mini-pump for a few pumps to make sure you have a good seal with the valve then unscrew the pump part to switch to the cartridge.

There are many types of co2 inflators that work differently, you need to tell what you have.
