JetBoil users beware
Please be aware that the new Jetboil stoves do NOT fit all gas cylinders, and they are only guaranteed to work on Jetboil gas canisters.
This can be a real, perhaps even fatal problem if you have carried you spare cylinder into the wilderness and it does not work when you screw it in.
I brought a new Jetboil stove when the old (faithful) Jetboil could not be repaired. The diffuser mesh and fibre got brittle and broke and they could no longer supply spares. So, first trip out all OK second trip all Ok, then came time to change gas, and nothing. Tighten the gas bottle, nothing, a full gas canister and no flow. Not too bad this time as it was a lunch time stop on a day hike, and I just got laughed at. Went home tried another cylinder and it worked. So, I tried my whole array of new and half used canisters. Some work some do not. I do not have any Jet boil gas, so I can’t say if they would do the same. It then let us down in the berg, with yet another new canister unable to push its gas through. Lucky we were just ay Giants hut fitting the new windows so it was not a crisis, but it could have been.
It was still in the warranty period and the store, Drifters, sent it back to Cape Town. It comes back with a clean bill of health, but still does not work on exactly the same cylinders that it did not work on before. So, they pull out their trump card. "It was tested on Jetboil canisters and worked and we (Jetboil) cannot guarantee that it works on other makes of cylinder. Sorry for you.
(This was backed up in a reply from Jetboil international.
SO, JA, 2 things, 3 actually
1. If you own a Jetboil and do not use the Jetboil gas, then please please please, test all the canisters before you go on an important hike/ climb.
2. If you have had the same problem let me know
3. If you happily use any canister on you Jetboil without any problems, then also let me know please.
Any other suggestions on possible recourse would also be welcome.
I had the same problem with my GO-System Cooker. I suspect that some of the gas canisters have the plunger set too low for the cooker pin to open the valve. I rectified the problem with the particular canister by temporarily removing the rubber washer from the stove. It worked fine then, with no indication of gas leak.
Take nothing but litter, leave nothing but a cleaner Drakensberg.
Again, I appreciate the recommendation and solutions, but I am not prepared to modify an almost new stove which cost more than 1 grand to just get it to work.
I'm still fighting and will keep you all posted.
Would there be any recourse in disputing their advertising their 'standard thread' claims?
Out of interest, the MSR Superfly has a fitting that they claim will fit "most self-sealing fuel canisters" (including Gaz). I wonder how truly universal it is.
From the Jetboil web site
Can I use Jetboil with other fuel canisters?
Jetboil is compatible with valves made to the EN417 specification, a standard adopted by manufacturers throughout the world. Please note that the product has not been tested with every different type of fuel canister, and we cannot claim safe operation with any canister other than our Jetpower brand of fuel.
Oh Boy, I'm just getting started, watch this space
Just had a look at my cylinder and guess what is printed in full view, just near the thread::: ta daa "EN417"
As I said, watch this space
And thanks again for the warning. Would hate to be tired and cold, and relying on melting snow for water, only to discover the stove doesn't work.
(Also one of the reasons I've been looking at alcohol stoves, no moving parts etc)
