Seems the Lindal valve is very inconsistent.
I will dispute this, on several grounds. First, Lindal must have made millions of these things, and they have not gone broke as a result of the valves not working. That in itself should make one hesitate. Secondly, I have a huge box of empty canisters, and the Lindal valves on them have always worked. Thirdly, I have refilled ‘a few’ canisters myself over the years, and that process has always worked fine.
The Lindal valves are very consistent – after the first million they usually are. But the pin on the connector which is meant to actuate the valve does vary between manufacturers. Some make the pin longer than it should be, so some gas leaks out as you make the connection, before the seal is made. Some make the pin a bit too short so you have to really screw the stove down hard to get any gas out at all. And some canister filling companies damage the Lindal valve when they crimp it onto the can, so that some connections to some stoves don’t work properly. This involves an adjustment on the crimping machine which needs to be monitored. I have seen all these problems.
A slight back-pedal is needed here. When I talk about the ‘Lindal valve’, I am referring to the B188 valve made by the Lindal group of Germany. I think it is reliable.
BUT! Rumour has it that there are Chinese clones of this valve on the market, and I have no experience of any of them. If the air horns are made in China, who knows where the valve was made? (But I still think the pin is probably the problem.)

Roger – These may not actually be lindal valves on these air horns or maybe modified out of spec on purpose to prevent attaching the wrong thing to them. The 1st manufacturer I tried recessed the valve so deep in the top of the canister that nothing could reach it other than the plastic horn. A second manufacturer I tried had non standard center pins, again, that only the rod in the horn could reach. Now that I have a couple that work well I’ll continue playing with it. :)Jun 12, 2019 at 12:19 am #3597280
OK, check the writing on the box and the can. Is the country of origin stated?
A more deeply recessed spigot may be intentional, OR it may mean a mis-adjusted crimping machine. I have seen the latter on some gas canisters.

The canister states made in USA on it.Jun 12, 2019 at 12:58 am #3597289
I can’t confirm if it is a deeper depressed pin. I need to devise a way to measure. I can tell you that at the moment I can get my BRS to vent out the gas from it but not from that 2-way $12 valve David shows on pg 1 of this thread.
EDIT** I can say that it is mucho easier to manually depress the pin on my 220g Coleman Cannister than it is to depress this air horn’s pin.Jun 12, 2019 at 5:45 am #3597332
I published an article on the Lindal valves back in 2014 which covers a lot of this. The URL is
The critical bit may be how far the spigot sticks above the rim. This photo shows a range of brands with different protrusions.
The amount of protrusion does not matter if the stove screws down onto just the spigot withOUT touching the rim. However, some stoves try to have a secondary seal at the rim, as well as the primary seal on the top of the spigot. I know that if the spigot is depressed too far, the stove can bottom out on the rim without having the pin work the valve.
In an extreme case, where the crimping machine was badly adjusted, the middle of the Lindal valve can be distorted downwards. This photo shows a good (or bad!) example on the right.
The red line on the right points to where the inner part of the valves has been depressed. It should look flat, as shown by the blue line on the left. These are actually old Coleman Powermax canisters, but you do get exactly the same with screw threads.
Funny story about the Powermax canisters and the Xtreme stoves. A lot of people had complained to Coleman that they could not get the canister to mate with the stove in the snow. Coleman could not work it out. The reason was that the canisters had deformed Lindal valves AND the cold weather made the sealing O-ring so hard so it would not compress. I discussed this with the relevant Coleman product manager, whose reaction was ‘Oh, that’s why they have been complaining!’ Lab testing, in a nice warm lab, had not suffered this problem (of course).
As a result, Coleman had the crimping machine adjusted so the top of the spigot was just level with the rim, and I think they modified the later versions of the Xtreme stove to have not one but TWO O-rings for sealing: more elasticity.
Can you photo the canister side-on as in my 1st photo?

Wow, that’s a bunch of variation! I can’t post a photo right now, but will. I looked at this closely when I first had the problem and noticed the variation and picked ones in the store that protruded the most. Mine looks most like the one in your top left #1 slot.Jun 13, 2019 at 2:12 am #3597545
Sure enough I do see the variation in the spigot height. The Coleman canister of course being the highest. I did modify my 2-way refill valve a bit to allow further clearance. I also dropped oil in the valve and manually actuated the pin several times. Not sure if that helps or not. There was also excessive rubber not centered and kind of protruding out. I cleaned that up carefully. I am now able to fill the canister but only in increments of 4 to 5 grams. The Shoreline Marine Horn seems to be the more difficult of the two to fill and it has the shortest spigot.Jun 13, 2019 at 2:54 am #3597560
Does the adapter hit the rim (on either canister) at all?
CheersJun 13, 2019 at 4:55 am #3597592
No, it did not come close to hitting the rim of either canister. BTW, I just finished filling the Shoreline canister without much problem after oiling and removing some of the rubber. It also only filled in increments. I may know why. While testing the run time when I first filled the Air & Stream canister I noticed the flame would die down at the end of each boil. The canister is so small that it may be affected more dramatically by temperature change. It got pretty cold in my boil tests and worked fine with a minor heat shielding/wind screen. Conversely, when filling, the canister warmed up pretty fast when accepting that warm fuel from the donor. Does this all seem plausible?Jun 13, 2019 at 5:45 am #3597598
Yes, certainly plausible.
You could try sitting the canister in a bowl of ice water (with ice) to hold the temperature low and stable when refilling.
You could also try sitting it in a bowl of ‘warm’ water when cooking, where ‘warm’ could be 10 – 20 C. When I do this I top up the bowl with a few spoonfuls of hot water from the pot halfway through.
Try it and report results? Interested.

Took my Air Horn canister BRS combo out for a field test. It was tough keeping the BRS on tight enough to engage the gas flow. It was much colder than I expected but above freezing. I need to see if I can do something about that. Refilling at home was attempted while keeping the donor in warm water. I was still only able to fill in increments. About 4 grams a whack. Maybe I should try making an ice mold for the air horn canister??Feb 14, 2020 at 7:13 pm #3631337Eric BlumensaadtBPL Member

I’ll stick with the small iso-butane steel canisters and my Brunton Crux folding burner – and try losing an few pounds on my love handles.Apr 20, 2020 at 3:57 pm #3642291David ThomasBPL Member

Someone PM’ed about buying some of these little canisters (empty) from me because he didn’t find any (plus shipping) that were reasonably priced. I slept on it, thought to google a few things and found that party air horns are cheaper than marine air horns, by a lot, and appear to use a similar canister:
I’m not sure it’s a Lindal valve but I’m sure that 3 for $12 off of eBaby including shipping out of California is a lot cheaper than the marine version.Apr 20, 2020 at 4:07 pm #3642293”V” (CzechClown)BPL Member
Yes, those are similar type canisters 1.0 – 1.4 oz. but they generally don’t have the screw top. The smaller horns are the key thing to avoid, they are pressed on.

Thanks, V, for catching that! Alas, I can’t go back and edit my post now.
I’ve found one of my marine air horns (with the aluminum cylinder) and will PM you when I find the other another one – the garage is in some disarray now with many spring projects after a snowy winter. Looks like I could send them USPS First Class in a small box for not much.
