Refill small propane cylinders Save $$ LPG Tank Bottle

so from time to time we all buy these small disposable one-time use propane cylinders or even these ones for your torch Both of these are empty you’re paying a lot though for the propane that is in these on average you pay somewhere probably
around fifteen dollars a gallon just for the propane in this little cylinder if you have put your propane refilled in something like this I just had this one filled two weeks ago i paid two dollars and fifty nine cents
per gallon to fill this up. Fifteen dollars a gallon verses two fifty nine a gallon i think i like 2.59 gallon.
For years I have been refilling my propane cylinders useing this little adapter. Now this is not
something i invented or that i came up with the chinese are not trying to make things to blow us up. this is something that’s actually you
buy from the store made in the U.S.A. and it is a propane filler coupler and it does work it fills our propane
tanks um… it’s completely safe the only thing is you don’t want to do it when propane tank is eighty-five degrees F or higher because as propane gets hotter it expands it’s higher pressure danger with you know an eighty five degrees this is probably closer to 200psi or something. It gets
pretty pretty dangerous at that point so it also don’t want you to put too much
propane into here. But also i wanted to show you guys that these are you can’t really over fill these by using this method and the reason why is you’re not actually filling it but equalizing the pressure so pressuring here is filling here the
pressure in here actually reduces overall the pressure in here equalizers with it what i did is I took the weights while they were empty this one is fifteen half ounces empty and say how much for prenatal This one will hold 14.1 ounces of propane. This one will hold 16.4 ounces of propane so let me show you how to do it you don’t need to do anything special
because you don’t need to purge them your don’t need to let every last little bit in their out
doesn’t matter ’cause it’ll just equalize with the pressure of this now per the directions you see this is
just outside temperature now i’m in this has been in a heated area this right here is about 65 F degrees this is a lot colder this is only 40 F degrees. I did
have it in the freezer 35 F degrees So it is around 35 F degrees This one should be a the same what would you recently cargo closed today or me take this he needs to do this on now every della profane those next wear gloves when the problems as though they both
screw-ups at ways kids proteins that was that so that’s we got now referred to subsec mail and turn it on that’s where the battle track does it really happy somewhat of a native just open it up but for that upside down what i’m doing because i’m feeling a smaller liquid and not gaffes is propane you want the liquid to come
out bureau for about a minute you can hear when it’s done and you will not have thing is you’ll
never kit that for now being here you’ll never get
the sixteen point four ounces in here sits down stargazing anymore its full so each other and flew back over that’s correct just like that weddings or w breaking it off if you wanna make sure that sealed puzzle soapy water right in there listen to a new shaking here guessing
but i was just a mall with soapy water picture the knowledge and so i had fourteen twenty five ounces muscle to be
able to put in sixteen point four so i should have twenty thirty about thirteen ounces should wait roughly three ounces if it was
completely full and we are sixteen we are twenty twenty-two it’s getting close to being refueled
yeah i mean it’s not even close to being over feel
the whole thing is probably so it’s about three-quarters way for you will get a bigger feel one of this is the colder this is that
this is a zero degrees and this is eighty degrees you we’re closer to a maximum deal that’s what you get that’s how you refill propane cylinder this one’s just the same threaded on this was full called off sps mister would roughly twenty houses windfall and this one waves unit but it shows that you know not over
field sheffield amount take that walk too fast and cost refilled this is separately da holds machines about four point you can see
gallon so this doesn’t hold a quarter of that
so it’s costing the forty cents to refill so that’s where my for painting scoffed viscosity forty
cents grip on the part about fortson was supported by wannabes forty cents with their ego guys thanks for watching comment below thumbs up comes down uh…
but you haven’t already subscribed excesses in back

    I taught the blue 1 says do not refill, and transport if refilled, I don't know I may have mistaken, what is the problem in transporting if they are refilled??

  • Milosz Ostrow

    It's not a bleeder valve; it's the overpressure relief valve. However, by pulling the stem with needle-nose pliers (wear protective goggles), you can bleed gas until a mist of liquid propane comes out. Using this technique one can actually overfill the disposable cylinder, so be careful. If you overfill it, use it immediately or bleed off some propane to get it to no more than 80% full.

  • Milosz Ostrow

    If overfilled, it may leak gas from the pressure relief valve during transport, posing a fire hazard, or if it is in an enclosed space, such as a car trunk, it could be an explosion hazard. Old disposable cylinders may develop rust inside, causing the cylinder wall to become weak and rupture, again posing a fire or explosion hazard. That's why the warning labels are there. Don't transport a cylinder or take it inside if it leaks after refilling!!

  • sixtyfiveford

    Very well said, Milosz. The Department of Transportation(DOT) regulates all transportation of flammable gas. The canister has been certified from the factory by DOT to be safe for an individual to transport. Once they are refilled the certification lapses. It is virtually impossible for a cylinder to rust from the inside unless someone has purposely let all the gas out and allowed outside air to enter the tank. It is more likely to have rust from the outside and a leaking valve like Milosz said.

  • The Electrician

    Awesome idea..don't know why it never crossed my mind before..I use to fill CO2 tanks the exact same way for my paintball games

  • ozzirt

    If you are not in a great hurry, leave the cylinder inverted and connected for an hour or two (even better overnight) It will be very close to full when disconnected.

  • ozzirt

    You will get a much quicker fill if you can have the cylinder being filled vertical a or as near to vertical as possible. Liquid gas cannot displace the gas vapour in the upper half of a cylinder lying on it's side without a lot of faffing about.

  • imgettinby

    Yes, sorry, I figured that out after posting. Don't know how that got turned on, didn't even know it was there. Thought it strange that your own subtitles would suddenly go so strange after starting out being fine. My mistake.

  • sixtyfiveford

    You can refill them as many times as you want as long the valve doesn't leak (couple dozen times). I have a propane torch and if I fill one and the valve has a slight leak a just put it on my torch or stove and it stops the leak and I can use the propane. After I use it up though I have to discard that cylinder. People rarely make sure their torch or stove has a clean tip when inserting into the 1lb propane bottle and that is how the seals wear out.

  • bogoff99

    thanks for this video, it confirmed what i thought about refilling.
    i have just got a refill adaptor and thought easy peasy, i mentioned it to a few guys and they ranted about overfilling and going bang, that didnt make sense to me as those large tanks cannot create more pressure than they have so how could the overfill.  the net is full of these scare mongers.
    thanks again be doing mine tomorrow

  • LunKerZ inc.

    I tried this, but the gas was leaking out after I refilled the small green tanks, so i just set them outside and let them drain. Do you have any tips for this? I did 3 in a row and they all were leaking..

  • Eric Schnidrig

    Yes!  You are correct.. As a ASE Certified Master Auto Technician for 0ver 38 Years, I never thought about the slender propane bottles being refilled for engine diagnostics seeking vacuum leaks!  Again, Thanks!

  • Ben Leddin

    absolutely brilliat 65 ford just ordered a transfer nipple from china today have bought a lot of these disposable canisters these last few years @ 15 euros a can        was just wondering can you transfer argon gas from a big argon bottle to a small mobile argon bottle i use with a mig welder thanks again 65 ford love your videos    thumbs up for the spark plug one 

  • Breakneck

    How exactly are you saving money doing this?
    In my neck of the woods, you turn in your old tank, pay $25 and get a new full tank.

    Seems like you'd spend $25 at least in them little tanks plus the time sitting there filling up.

  • chaba72

    mine dose not work ! when I turn on the tank ,gas is barely coming out, not enough pressure to fill the 1lb tank. there is something in the adapter that prevents the gas from coming out.

  • H-K-J Jorg

    Instead of ordering the valve on line why not try a hardware store or tool store like harbor freight in your own home town I don't like waiting 😉 

  • brightspark54

    those blue throwaway cylinders have a spring and a rubber ball in the neck in case u have a blowback on the torch and wont refill properly

  • holdengr

    I bought one of the couplers a couple years ago to refill the 1lbers for my lanterns/cook stove (at my remote camp) using the 20lbers. I was always a little worried about trying it.

    Not anymore, thanks.

  • Brad Sanborn

    As I read the law, it is not illegal to refill or use disposables on your own property as long as you NEVER transport refilled disposables over ANY public roadway.  However, just because someone manufacturers an adapter does NOT mean it is safe to use. First problem I see is that when a 20# tank is inverted, you have bypassed the internal safety devices built into it and ignored the manufacturer's instructions to always keep the tank upright.  Another fact here is that the pressure relief valve built into disposable cylinders is calibrated for a specific pressure release and NOT designed to be pulled or pushed on- not that you did that.  Next issue is that the disposable tanks are built with a cheap rubber O-ring and are not engineered for prolonged, multiple uses.  The final big problem with refilling is that the propane filled into single use cylinders at the factory is DE-humidified to prevent the cylinders from rusting from the inside out! Commercial propane bought retail/wholesale in your 20# BBQ tank is NOT dehumidified and does not need to be because those tanks are designed and certified to be used and refilled that way.  Facts are facts…
    Save yourself the hassle and danger and use certified, engineered, and legally refillable cylinders available at   Excuse the informative yet shameless plug for my website. 

  • Floyd Lenhart

    Awesome! I hate throwing away a perfectly good 1 pound can. I'm going to start refilling them and use them over and over. And save money to boot. When the can is no longer usable for propane I will cut it open and use it for a foundry insert. Hah! Thanks for sharing.

  • Frank Corley

    Thanks for the video, I just got my adapter and filled a bunch of bottles last night.  Two questions came up.  First, they don't seem to fill anywhere near as much as the new bottles.  They are much lighter.  Is this because it is about 20-25 degrees F in my garage, therefore reducing the pressure available to force the liquid into the empty bottles? Can I warm the large bottle in the house and then more propane to transfer?   And don't worry I won't do the transfer in my house or in a closed garage I'm familiar with the need for ventilation.

  • penguinistas

    I believe the reason that the cylinder is not completely filling is because the liquid propane can only flow into the cylinder while the gas in the cylinder can flow out.  After the cylinder is about 1/2 full, the cylinder opening is submerged in liquid propane, preventing any additional propane gas from escaping.  After that the bubble of propane gas still left in the cylinder compresses until the pressure on the gas bubble is in equilibrium with the weight of liquid propane trying to enter the cylinder.  I believe that you could recharge the cylinder more fully by tilting the small cylinder down while it fills (allowing more of the gas bubble trapped in the cylinder to escape).

  • Mike Mcculloch

    In practice I heard of an issue where sometimes after enough use,the threaded neck on the disposeable cylinder cracks and leaks.Then it burns like a flare.Off to the empty cylinder bottle testing lab.Good demonstration.

  • Love2boat92

    How does the liquid propane get used up in the torch? If you fill it up upside down then why don't we use it upside down to get all of it out?

  • Kelly Gerling

    Are the adapters that work on smaller 4 ounce or 8 counce canisters for backpacking stoves? Here are two examples:

  • John .Eiring

    Does the big tank have to be full? I have watched many videos and cannot get this to work….I've tried the forceps, the freezer….everything. I even bought another adapter. It only puts in a tiny bit. When you open the valve, it hisses for about 5 seconds and that's it. Could it be the altitude? I'm in Denver.

  • TheBo0mer

    So basically, the company labels them "Do Not Refill" so they can make more money? Serious question. Just wondering if they're physically able to be used many times. It wouldn't surprise me if it was the former, though.

  • Nancy Crane

    Wow I didn't even know you could refill them. we have thrown so many away. we use them for everything. thank you for sharing. now we can save some money

  • sixtyfiveford

    Check the video description for where to get one of these. Temperature difference is the key to get maximum fill. A freezer temp (0-20F) 1lb cylinder and a room temp plus (80F) large tank will give a 90-95% fill

  • Paul Gumper

    I can't seem to get any gas into my small tank, even with the big one upside down. My big tank is a Blue Rhino, could that be the problem?

  • Tuesdays Runner

    It would be good if you would explain where you go to get your propane refilled for so cheap. As other reviewers said, people go to exchange the whole can and not just refill it. What kind of place refills propane? And you are only getting maybe half full?
    Here is the problem. I was looking at how to refill camping fuel with a 70/30 butane/propane. since a small can is maybe $5.
    Note that Youtube didn't have a way for me to just get notified of comments for just this video and I was getting tons of junk mail from Youtube so I may not know if you reply to this comment!

  • Double Nickle

    Didn't know you could do this safely. I'm not up for a "Hey Y'all Watch This" moment. LOL. Thanks for the video its gonna save me, and I suspect many others, mucho denaro.

  • screemer122

    the first time i seen one i knew what it was for ..great thing ..great video .ps i am from ontario . hard to find over here

  • Casey Urquhart

    Dad taught me this years ago, it's great. If you get one that is leaking from being too old you can throw a torch head on it, that usually takes care of the leak.

  • BlueEyedBaby420

    thank you! this is exactly what I was looking for haha. nice when the first video that comes up is what you need to know😄

  • Curran Kemp

    Just saw your video and I am heading to the store to get an adapter. I plan on refilling a few spare bottles I have lying about my house. I just wonder if on can do the same thing with transferring from a say 300 gallon tank to one of these small bottles (given the cost of propane will run around $1.50/gallon, and would basically cut the cost of refilling the small tanks down to say 20 cents). I also like the idea of recycling the small bottles and just not throwing them away; seems like a waste.

  • Gary Kovach

    Sanborns comment reminded me of the "Chewleys" salesman from the movie CLERKS. The end shameless plug was priceless. You can gather quite a bit of very useful info from YT, but you also have to have a bit of common sense, ignorance is the biggest danger of all. Good video.

  • larry white

    Where did you purchase the adapter.  I saw it on Amazon.  I like to spend my money locally if possible. Any info would be appreciated.  Good video.

  • Browarus Pierogus

    I wonder if you could just vacuum the cylinder with pump first and then refill like that. I'm guessing pressure would have to be negative to originally measured when full bottle.

  • Rickarama Trama

    I like how you don't fool around and get with the program. Me too~!! Thanks for this great tutorial on how to fill these little tanks cause I have been saving them empty until I could get the time and desire to fill them. Now you have given me a will to do so. Rock On~!!!

  • Latin Dance Videos

    Just be careful with pressure ratings. Some smaller disposable gas cylinders will have lower pressure ratings than the larger gas cylinders.

    If it's not stamped with a certification number, don't.

  • simon esteva

    a tip to get a full canister, fill for a minute at room temp, once its equalised, put the small canister in the freezer for an hour or more, then decanter the rest. it will fill .

  • Back to the Basics 101

    Thank you for the great video
    I bite my refiller connection years ago. I was going to do a video on it in the future. Thanks
    Happy trails

  • Tony Robbins

    I use the 1 pounders in a buddy heater in my van in the winter when I hang my hammock in it while doing trail maintenance. I refill mine as well, but I can get a 100% refill by doing one small trick. I have a pair of 90 degree forceps to clamp on the pressure relief valve and pull it out releasing the pressure until the bottle is full. It is the same concept as filling a larger vessel. When liquid propane starts to spit out, stop filling.

  • Cayoot

    Great video, thanks. I've been doing this for years, but I have one problem that I'm hoping you can help me with. Quite often, the small cylinder that I refill won't seal. What do you do when you have this problem? Only thing I can think of is to screw the tool (torch or what ever) onto the tank right away and make sure it's turned off. What's your thought on this?

  • Nginmu Mbetse

    Is it possible that as the liquid propane drops from the big inverted tank into the small tank, air in the small empty tank bubbles back into the big tank? So, if you filled many small bottles over time you could eventually end up with a large tank containing a small amount of propane and a fairly large amount of air.. could this be an ignitable mix? Do the gas companies normally fill the 'dead' space in these tanks with something inert like pure nitrogen to prevent that possibility? IDK, maybe you should blow some CO2 into the empties before filling.. maybe it's safe enough seeing as there's not going to be any source of ignition inside the big tank anyway..

  • Desmond Bagley

    ……..yes,, I've made various types of adaptors for all these tanks too… There's the ongoing confusion for those of other countries when American s refer to gasoline as 'gas' have gas and you have 'gas' ..We have LPG which is liquid petroleum gas and can be propane/butane mix for vehicle fuel or pure propane for domestic and camping use ,there is pure butane for some disposable camping gas cylinders and cigarette lighters and the butane needs only moderate pressure to liquify at normal temperature,, the pressure required for butane is so slight that even plastic serves as the gas tank as is the case for cigarette lighters. The 50/50 propane/butane mix for vehicle fuel doesn't require more than perhaps 3 atmospheres to liquify…There is also CNG which is compressed natural gas (methane) and it's merely compressed but not to point of liquification,, it's a fairly high pressure but it gets exported to Japan and China in white painted giant sherical tanks on purpose built ships… Perhaps viewers would find it useful to lookup methane through to heptane…the tanks should be refilled according to weight with them the tanks placed on a scale cos it's good idea to stick to 80% full capacity ,,in New Zealand its 85% full capacity for safety sake……. a well guarded secret for good reasons is that the 50/50 propane/butane mix is excellent as a refill in vehicle air conditioning systems and more than rivals the old original ozone depleting stuff..

    Hi from Oamaru New Zealand. I cut those spent out of date bottles to mug height to store tools on shelf like punches and chisels.
