99.9999% sure but…

> Are the snowpeak, jet boil and MSR all interchangeable? thanks.
ALL screw-thread canisters are interchangeable.
Heheh – most of them come out of a single plant in Korea anyhow!
But there are minor fluctuations in dimensions which usually do not cause any problems.

That said … not all stoves are exactly interchangeable. Some stoves have slightly longer (or shorter) valve pins than others. Some stoves have a jet-size and air-inlet combination which deviate enough from the 'average' to cause slight problems with some gas mixes. They can flame out.

Only recently has there been a publiched standard for the dimensions of the screw-thread part of the Lindal valve. Prior to that different manufacturers had slightly different measurements.

However, while the canisters are largely the same, we cannot say that for the contents. Canisters filled in USA (if there are fillers any left) or Korea contain fairly clean gas. They are good. But some brands of canisters filled in China are KNOWN to have very dirty gas – lots of fine dust. This does not matter too much for an upright stove: the dirt stays at the bottom of the canister. But for a winter stove which uses an inverted canister – instant disaster! Blockages everywhere.

As far as I know, the MSR, Coleman, Kovea and Snow Peak canisters are fine. The white Primus canisters were fine last time I checked. Some of the other Primus canisters and I believe the Jetboil ones come from China. I found huge amounts of dirt in the non-white Primus canisters, and had to return them.

So just make sure your local shop gets good ones. The real cheap non-white Primus ones are Chinese and BAD, BAD, BAD.

Roger mentioned the mechanical interchangeability of the fittings. However, the gaseous fuel itself comes in different blends, so it is not all equal. It will generally function in all canister-type stoves, but to different degrees. As a general rule, the more propane is in the blend, the better it works at cold temperatures.

"So just make sure your local shop gets good ones. The real cheap non-white Primus ones are Chinese and BAD, BAD, BAD."

And i bet they have made you MAD, MAD, MAD and possibly also SAD, SAD, SAD? Hopefully no letters were involved… Moral of the story, go with the stuff made by the Korean Plant and not the Chinese Plant, too bad there is not an English Plant..wait a minute….

(Zeppelin song reference, total thread derailment for the sake of mild and korny comedic purposes.)

> too bad there is not an English Plant
The UK company EpiGas which started the whole Lindal valve detachable canister thing is now owned by an Asian company. Sad. They used a screw-thread. The French Campingaz company developed a rival fitting. Much better design, but the French kept it within France. A pity.

And the white Primus canisters are which ones ? I know the Powergas-canisters (in fact the only Primus canisters I can find) but are those the wright ones ?

So back packing stoves REALLY are Rocket Science !
no wonder I rarely bring one …

I can get those canisters around here, well, Big Five had them last year. Very nice attachment but kinda bulky and seemingly heavy.

Have seen those overseas – nice to know they are local too – is the gas considered clean?

I don't know, but I have never had a problem. However, I have always used them upright, so…

Hi Woubeir

> re those the wright ones
Oh, VERY good!

My experience has been that the Primus canisters which are white with a black band around the top with 'Primus Power Gas' in red on the black band are OK.
Caution: things can always change.

Cheers

I have always found the Campingaz canisters to be clean.
In fact, if I were to ever consider refilling my Coleman Powermax canisters, I would use the 450 g Campingaz canisters as the source. Illegal, of course …

Cheers

Good to know about the Camping Gaz – so they have the best attachment mechanism?

Is there any advantage at all to inverted liquid feed in warm weather?

I tried that out just a few weeks ago when out with my Kovea Spider. It was about 65 degrees and when I inverted the canister it really increased the output. How much? No idea but it was way more than I needed to boil about 600ml in a few minutes. I had to turn it way down to keep the flame under the pot.

> Good to know about the Camping Gaz – so they have the best attachment mechanism?
Well, there's no thread to strip on the stove! Much better design.
The Coleman Powermax is also good, but rather complex. I have made adapters for the Powermax with the hex keying system, but it was not easy.

> Is there any advantage at all to inverted liquid feed in warm weather?
Not really. You might be able to get more power, but that is a silly and wasteful exercise.
