Question Concerning CO2 Inflators
 
I just got a Genuine Innovations Ultraflate. I want to store one cartridge in the chamber. Should I screw it all the way in now, or just part way in (so that the seal is not punctured)? I'm guessing that if I screw it in, there's a danger that CO2 will leak out.

Why not just store the cartridge upside down / inverted? Have been doing this with my Ultraflate for the last couple of years with no issues. You could screw in part way, but as you have to dis-assemble to screw in fully, I just leave inverted.

For storing screwed in, the only risk is that if the safety gets knocked off, and the trigger is depressed, the CO2 will be released.

If it is pierced, even if it is not being triggered, it will eventually leak out of the cartridge.

Agree with put in inverted.

You sure it's threaded? I can only find images of the ultraflate plus, and they're not threaded. I like the threaded cylinders because the inflator head is tiny, but the unthreaded cylinders are much cheaper to source.

In any case, don't buy them at a bike shop... you can get cylinders in bulk from places like Amazon. And don't install the cylinder until you really need it.

The Ultraflate plus will take threaded or unthreaded cartridges.

The cartridge it came with is unthreaded. When I talked about screwing it in, I was talking about the holder.

Right. I got these. 66 cents each. They should be just the right size.

BTW, this product doesn't make sense to me: http://www.stayfill.com/index.html

The tires stay inflated, which is great if you never get a flat. But a cartridge is 115 grams, will fill three road tires, and costs $30.

Ah, good for you then. Bike shops charge crazy prices for those commodity things.

As for the stay fill..... ugh. Nice double entendre, I'm sure a 16 year old wrote that copy. they're probably nitrogen molecules, which is great, but... who cares. Cyclists tend to fill their tires daily and it's no big deal. I don't want to pay $30 to fix a flat though.
