Does co2 go "bad"?(7 posts)

Does co2 go "bad"?DINOSAUR
Nov 20, 2002 8:15 AM
I had the dreaded "F" thing yesterday and I went through 3 1/2 cartridges of co2 until I got enough air into my tire. This stuff has sat in my seat bag for awhile and was green. Anyone ever had this problem? I was thinking of wrapping them in cellophane, or maybe just bad technique on my part. It wasn't that cold (in the 60's)...also the valve on my Torelli mini pump was all dried up and wouldn't make a seal. What's a good lube (vasoline?)... the pump gets lot of muck and dust and seldom sees any use (accept after posting this, I'm sure)........
No, sounds like a connection problem. nmMB1

At least some CO2 cartridges must be used upright...PdxMark

meaning that the cartridge must be pointed toward the sky when you press the trigger. For me, this means that the wheel has to be sideways (on my lap), not on the bike. Otherwise the cartridge freezes up and won't fill your tire. To help me remember I marked a big arrow on the CO2 filler.
Backwards (I think)...TFerguson

Maybe I'm just reading it wrong.

The cartridge is full of liquid CO2. If held upside down, the liquid will "poor" into the tire, then expand - freezing the stem and not doing much for the rubber. If held upright (filler nozzle at the top) The CO2 will evaporate in the cartridge and go into the tire as a gas. It doesn't have to be perfectly upright and can be done on the bike.
If it went ssssssspt and got cold, it was still thereKerry

CO2 can leak out, but it doesn't go bad. Wrapping a brass cylinder in plastic will not reduce CO2 losses. If there was a lot of hissing and the cartridges froze, then you face an operator error problem.

It most likely was operator error. I've only used this stuff about 5 times (knock on wood), since I started carrying it back in Feb of last year. I just used it the day before with no problems on a different bike. I jammed my thumb and it messed up my technique...oh well, I picked up 15 new cartridges today and I'll see how it goes next time...For some reason my flats always happens in series of 2...the Park Glueless patches also work great....
Sounds like the title to one of those bad shows...James OCLV
