Jetvalve CO2 Inflator (Head / Cylinder / Sleeve)

It's not immediately obvious, but the black collar between the canister and body has to be removed so the canister will work. Think of it as a safety thing, just no instructions to say it had to be removed.

I bought a much cheaper version from a well known auction site and it fell apart the first time I used it. This item is much better, works reliably and the seal seems to be good enough that any unused CO2 is still there next time you come to use it. It does get very cold in use - it runs on pressurised gas so it would do, there's nothing anyone can do about that - and I think perhaps a bigger, bolder warning could be in the instructions, but I'm only mentioning that, not moaning about it. I'd certainly recommend this to anyone looking for a reasonably priced gas inflator.

Great little valve. Well made, feels like a quality item. Had cause to use it twice recently, ( first punctures for ages!) so I'm glad I had it, and I have to say it performed perfectly. Good price too, no need to spend 15 - 20 on one. Happy.
