Refilling Isobutane / Propane Canisters

[@wanderworm]

Freezing the one you want to fill is based on the Ideal Gas Law which is PV=nRT where P is pressure, V is volume, T is temperature. If you don’t make one canister colder the gas will only flow till the pressure is equal so the full one would fill the less full one till pressure is equal (gas flows from high to low pressure). Making the recipient canister super cold means the T on the right side of the equation is lower so something on the left side of the equation must be lower too in order for the equation to be equal. The volume V remains constant so the only part of the left side that can change is the pressure P which must be lowered to balance what’s happened on the right side of the equation. So freezing causes the recipient canister to cool and lower the pressure. This results in the partially filled canister being higher pressure relative to the recipient so the gas will flow from the partial to the recipient as desired.

[@SeniorHiker77]

Wow I guess you right. Lol. Thanks for that comprehensive explanation. 👌👍

Thanks. Found the adapter on EBay and thought “hey that’s smart”. Tried it last night and it would only work some of the way. Overnight I thought “huh, maybe a combination of ice and heat would work”? First thing in the morning I found this video and I agree, some minutes in the freezer is both easier and safer. 😊

[@henryvanderbeek2973]

Yes, put the receiving canister in the freezer for till it's very cold to lower the pressure and you can also heat up the filler canister under hot water, to increase the pressure in that one....I have a different set up, but it works...

[@djkmark]

I came across your video and channel a few months ago and decided to buy one of these valves. I finally got around to buying one and received it yesterday. I started with a small MSR brand canister. On the side of it it has gross weight (canister full)7.40 oz and net weight (canister empty)3.90 oz. I weighed my empty canister on my kitchen scale and it was 3.55oz. I had taken a cold-weather backpacking trip a month prior to this and my stove struggled in low 20° weather. I decided to fill it with propane from a Coleman 1 pound propane cylinder. I have an adapter that fits the 1 pound cylinder so you can use a backpacking stove on it. So after I filled it and weighed it several times to match the net weight I put it in the freezer for one hour took it out attached my backpacking stove, fired it up and it didn’t spit, sputter or anything with the propane. Keep up the video’s and happy hiking.

[@SmellNRoses]

Excellent tips, my friend. I’ve been refilling my canister for years too. Saves a little money plus you can always be sure to have enough gas for each trip. I don’t always freeze the empty bottle but what happens if they are the same temp is that you can’t completely fill the empty one. It will fill about half way or just a little more. Definitely need to chill it if you want to fill one all the way.

[@SeniorHiker77]

Actually I quit refilling just use until completely empty then punch a hole and throw away. I started carrying an extra full canister. 👌

[@SmellNRoses]

@@SeniorHiker77 it is an extra step. I like to refill mainly because those small ones are hard to get in my area but I can find the larger ones everywhere. If I could easily buy the small ones I’d probably not bother with filling.

[@kke]

@@SmellNRoses yeah the small ones are always out and the big ones don't fit inside my pot for packing. per gram price on the small ones seem to be almost double. it's not going to break my bank, but i don't like to feel hustled. the small ones you practically only find from hiking/outdoors stores, the medium and large ones are everywhere.

Thanks so very much!!! I have heard about this tool but was hesitant! I would be worried about over filling. I plan on buying tool ASAP and taking on trail with me.

[@psyamok3735]

When pick one up at hikers box, put the can that you want to fill in the cold stream water and the one you wsnt it empty under the sunlight for 2 min, then invert the one under the sun and do the fill transfer, you will get the same effect. It is hard to over fill on the hike cuz both loss pressure aftrr use and during transfer they just equalize pressure at same temp.

[@paulahavens2764]

thank you that is a great idea. Wish these canisters had a gage on them to make them safer,so when you would know if they are empty or when you had filled them up.

[@Pandainapandasuit]

Float method eh?

[@WildlandExplorer]

Another KZbinr indicated that chilling the receiving can has resulted in the bottom visibly bulging out after it raises back to room temperature. He verified that the small can was stock full weight of 7.4 oz. As the can temperature raises back to thermal equilibrium, more of the fuel within vaporizes and raises pressure in the can. It's advisable to just mildly warm the donating canister(s). Say by holding them under your shirt for a half hour or something to get them 15+ deg above room temp. And just keep the receiving can at room temp for safety. Should work just as well but is safer. Honestly I'm not sure why this is happening as the operating range of these canisters is down to freezing. Maybe the guy's scale was wrong and he overfilled it. But it's mostly likely because these canisters are filled at the factory at a calibrated ambient temperature. Either way, from my perspective, not worth messing around with.

[@SeniorHiker77]

Hey I like your process will try it next time, thanks WWH.

[@SalineScott]

That’s a great idea. My canister last so long that I don’t think I’ll be worried about refilling them. I know it would save money over time though.

[@dannygarden464]

I see alot of comments but I'll say it anyways, they recommend colder temps because it's easier and get more gas in the tank in liquid state than gas state, the opposite when you use it, some people put isolated skirt around so the gas state get out easier, I don't remember the ratio but it's still something, anything that can save a little bit is always better than nothing, I think it's close to 10-15%, hope that clear enough with traduction. :)

If you refill an empty cartridge with a full one, how does that help? The pressures equalize, and you now have not one empty cartridge, you have two half-full cartridges.

[@CampingrocksBgWoW]

You freeze the one to be filled so that you can fill it up. The whole point is this - the smallest 100 grams canisters are very expensive, the 450 grams canisters are the cheapest. You keep carrying only one 100 grams canister and use it, keep refilling it from the big ones and thus achieve substantial savings over time.

[@wanderingcalamity360]

@@SeniorHiker77 Not a bad idea, either. There's a few options for adaptors that work for butane and propane, which then connect to the transfer device so you can make your own 4 season fuel blend that won't wimp out on you in winter. I'm looking to put a little kit together for doing so. The benefit of the campstove canisters, for me, anyway, is that the campstove canisters are somewhat thicker and stronger than the conventional butane canisters and I can fit 2 of the little ones in my little Stanley cook pot perfectly, with room for my stove under the pot lid. I like the lower profile of them for cooking on, as well. But I can certainly see the allure of ditching the campstove containers altogether.

[@TheTekSone]

I bought a digital kitchen scale to weigh mine. I use the jetboil cans. I know that the jetboil 100gram cans when empty are 94grams (g), 194g when full. The 230g cans when empty are 126g, 356g when full. the 450g cans when empty are 195g, 645g when full. you can also use the transfer tool to empty a can completely by heating a can then turning the valve to let any trapped gas/air/pressure escape. you can weigh your cans while empty and use a magic marker to write on the bottom how much it weighs when empty. once you start filling them up you can start and stop at any time to unscrew and weigh. I always fill 10g less (put 90g in a 100g can) because with temp changes the can builds pressure. today you can weigh a can and it says 194g and tomorrow can be a warmer day and it will say a different temp which may be over.

[@TheTekSone]

g g I am in the US. I used “grams” because I wanted to, the can is measured in grams and ounces. If you have a digital scale does it really matter what I measured in? Most digital scales measure in multiple units (lbs, grams, ounces, etc.). If you have a non-digital scale, convert it. Either unit is not the right or wrong way. It is about how a person wants to measure it. I used grams. Have a blessed day! :)

So it has been awhile now do you still like refilling these? I love not having to trow them away. But can I still trust the pressure if I'm out with it?

[@SeniorHiker77]

I moved on to the pure butane canisters at least for the summer.

[@outdoorjunkie2483]

Senior Hiker 77 I kinda thought somewhere along the line I thought you said that somewhere. With little ones I can’t upgrade equipment Often when buy new shoes ever 3 months as they grow🙄 so for now I’m sticking with the stove I have . But I thought refilling maybe be nice. But I guess really in the end you still have a can left over either way

[@SeniorHiker77]

Yep I haven't got the full solution yet.

[@PAPYRSEH]

where do you live? it looks cold.

[@SeniorHiker77]

Not cold, Georgia USA.

Thankyou SH77 !

You are welcome Mini.👍

So how come the containers don’t just reach an equilibrium? Some of you say we are freezing the receiving container? That would lower the pressure, but I mean, physically there isn’t a way to really empty empty the donor canister, is there?

[@SeniorHiker77]

I come to realize that the only way is to use a canister until it's empty then punch a hole using an aluminum punch then throw them away. Thanks for a very thoughtful comment Michael. 👍

Any time

[@rockclimbinghacks9222]

Awesome!

[@johntuttle4486]

You don't throw it away, you RECYCLE IT!

[@SeniorHiker77]

Didn't have enough room to keep any more. Lol

Not like this entirely unsafe or anything. But just a couple warnings: ."Disposable" tanks should not be "refilled". .Buy a refillable tank that is d.o.t. approved and has a bleeding valve. .the d.o.t. portion serves to allow you to legally transport refilled gas cylinders, and safely. .Do not transport refilled gas cylinders, that are one use(disposable), because this could be illegal, potentially dangerous. I think if your refilling, you need a tank that has a bleeding valve. MOST IMPORTANTLY. Do not put straight propane in a propane/butane or propane/isobutane cylinder. The thin walled cylinders that have these mixes are made for these mixes that are lighter and more easily to carry. As well, the butane portion puts out more energy with less gas spent, making it more efficient with the amount of volume. But putting propane in the mix cylinders that have thin walls could be a problems. Propane needs thicker walled tanks.

[@Pandainapandasuit]

one last note: The bleeding valve is helpful bc it will alert you when it's full.

[@SeniorHiker77]

Actually I quit refilling my canisters. I carry a full spare and the one I'm trying to use up. Don't forget to use an aluminum punch to put a hole before disposing that canister.

[@michaelrs8010]

Newbie here (with some decades behind me not new to life but new to this stuff) with a Q for anyone who knows: So I just got the AOTU stove and a Toaks 750 ml cup and did a test boil with a standard Primus 8 oz canister. I found I could not make the 3 minute boil time unless I cranked the thing up to what seemed like all the way AND, in the bottom of the cup, there was a quarter sized bright red spot, as if the thing might burn through the bottom of the cup. Sooo, all systems normal? Something might be wrong? Please advise. Thanks.

[@SeniorHiker77]

I never liked any store that burns like a blow tourch for that very reason. I always felt like it would burn a hole in my titanium 750 pot. I personally use a Snow Peak Giga Power or the Litemax seem to have a softer flame. Hope that helps. ATB

[@azclaimjumper]

$29.95 on Sale on eBay as of today. This is the lowest price ever. And quite likely to be even lower AFTER New Years'.

[@SeniorHiker77]

Thanks for the tip AZ.👌

[@adventureswithfrodo2721]

Those butane cans do not like cold weather.

[@SeniorHiker77]

That's for sure they don't like cold weather. Lol

[@colinevans7134]

In the video, your filling one gas can to another gas can and are the same, so why don't you use the one with gas in Thay are the same can so you don't need to do that

[@SeniorHiker77]

I don't do that anymore I just use them until empty, punch a hole and throw away. Thanks for watching one of my old videos. Your comment is greatly appreciated. 👌👍

[@theMekanik]

I will probably refill them with 1 pound propane...... propane burns hotter. Thanks for the idea

[@TheTekSone]

I read somewhere not to refill the isobutane cans with straight propane. the pressure of propane is too much to handle for the thin cans. that is why propane bottles are so thick and heavy.

[@lakorai2]

These canisters cannot handle pure propane. Refilling with regular propane is dangerous and definately not DOT approved. What I would recommend is purchasing the FlameKing 1lb refillable propane kit and empty tanks. Theese are the only 1lb DOT approved tanks that you can buy that are refillable. The main disadvantage of course is they are heavy (2lbs 8oz when full) and probaly not the best for backpacking, but perfectly fine for car camping, tailgating or RV use.

[@catlady8324]

If it’s so cold outside that the butane won’t boil (no pressure), then I’M NOT GOING camping!!! 🥶

[@SeniorHiker77]

Thanks for stopping by happy New Year

[@jsplasha]

Out of all the things to refill these are the dumbest because they have the worst valve design out of any of them and no way to vent excess pressure unless you have the one type of adapter with a pressure release. That being said, I like to run propane torches on the odorless blend of LPGs you get from headshops that they use to make BHO or the ones from the UK that addicts sniff and the easiest and safest way I've found to do that is to refill the odorless butane first into these canisters and then into the propane canisters because there isn't an easy way to go right from those plastic adapters on a can of butane into a 1lb propane tank without first going through one of these flat gas canisters and I haven't died yet. I'm not saving a few bucks though I'm taking the most expensive LPG and putting it into the cheapest canister and losing 20% in the process but I fing hate the smell they add to propane

[@SeniorHiker77]

I don't refill those canisters anymore. I just use them until empty punch a hole then though away
