WOW, just a few days ago I mentioned refilling these little one pound tanks on a forum and had folks jumping up and down about it, Been doing it for years and pleased to see you doing the same.
Been doing it for several years now. Although I am sure that you never get a completely full bottle, I count that as a plus if you live in a warmer climate, as pressure grows with heat. Putting them in the fridge first, does give you a fuller fill. But I agree it really isn't necessary, especially if you let the excess air out first or between partial fills. Also it may take a little longer to fill a 1lb if the 20lb is low or almost empty. As always though, thanks for putting it out there because for every one of us old timers that already know something, I am sure there are hundreds that didn't. And in today's world every penny adds up.
Yep… for sure. If there is a little bit of propane left in the bottle when you push the stem in to let some of the air out the bottle will start to freeze and I almost always get a complete full bottle at that point sometimes they’re so full they hardly even shake. But leaving a little bit of room is probably better like you said in hot climates but there is the expansion valve on the tank that should be plenty of protection that valve actually pushes out if the pressure grows.
Hey Elvis, take it to the next level. Call your local gas LP dealer and say you need a 100 lb bottle for you house stove or whatever. Then you can fill up the 20 pounders as well. Lp is usually around 2 dollars per gallon or less in WI. You can buy a 100 pound tank as well for around 160 at menards.
That's a very good idea on filling those tanks. I always take them to range and blast them. Even when they don't burn but still have liquid in them . Thanks for tip.
I live in Wisconsin. If you do that in the winter in Wisconsin, you have to have the 20lb propane tank inside for a few hours because at -15°F a full propane tank has almost no pressure. Higher temp=Higher pressure. That's why some say to put the small tanks in the freezer. If they are not completely empty, it makes the remaining propane liquid and you can just "top them off" so to speak.
I have been heating my Garage with a 20 pound propane tanks and I always feel like there’s some propane left in the tank if I bring them in the house for say an hour do you think I’ll get the last bit out of em I’m in Michigan by the way and right now 11/20/21 it’s getting around 20 degrees out so the garage gets really cold
@@Johnny-jr2lq Try it...I am not sure about 20 above but when its 20 below a full tank barely leaks out any gas at all. I had some friends who were potters with kilns that were hooked to a big 500 gal tank. They used to have to build fires under the tank and put big blankets on top to heat it enough to fire the kilns in the winter.
Been doing this for years for icefishing with my Mr buddy heater and Coleman Stove and lantern... And yes it does help to put them in the fridge not freezer. Great video and way to save money 👍👊😎🇺🇸
Great video Elvis. Didn't know to bleed the air out of the cans. Was only getting em to fill only about half way. Will certainly give your method a try. Thanks.
I've been refilling my 1# tanks for several years. The adapter I got was from Wally-world, and ran about $15-$20. It's paid for itself multiple times over. Good tips on filling the bottles, Elvis 👍🇺🇸
Suggestion, use a scale and measure a new bottle and fill the old one never more then the Orginal full one 😊. You could write the full and empty weights under the bottles. 😊
Great video Elvis I wanted to tell you how much I appreciate you uploading a video a while back about DuPont/IMR/Hogdons 700x in 223 with cast projectiles. Went ahead and tried that load out and it ran like a champ out of my Mossberg patrol scout gun.
Thanks Elvis! I've seen those valves, but I've never bought one. It's definitely on my list now. I have a couple of the Mr. heater buddy heaters. This is going to be helpful.
@@Jerry-dk8se I have a week house with no heat. It's where I sir all my tools, and my get away place. We also, and by we I meant the test of the family, used them for camping. My back is so messed up that's something I don't think I'll ever do again.
One thing I would add is with that type adapter I would put some lube on the O ring. I had a new one that the O ring was cut into by thread burrs after just a few times. I bought new O rings and lubed it now it works just fine. I also bought the type that screws on the outside threads which I like better.
That’s a fine idea my friend! It’s impossible to detect in the video but once the rubber seal makes contact it has that rubber on rubber grind… I’ll be lubing the washer! 👍👍👍👍
20lbs for $15. Or $1.33 a pound. Vs. an average of $8 a pound, when buying the camping bottles... People crying about not getting the can 100% full... Are you kidding me? If you only got every bottle 1/2 full you STILL SAVED $4! or half the price of the can. Who doesn't want to save 50% on the fuel cost? Either way, Its full enough and you wont have to buy extras on your next outing. Thanks for posting this! I have been saving those little green cans for a while now!
20lbs for $15 is $0.75 per lb. You divided wrong. But when you get a tank filled they usually only have about 17lbs in them...Still less than a dollar a lb.
If there is a small amount of gas left in the bottle when you push the stem in to let the air out it will also freeze the bottle and do the same thing. There’s a little tip for you.. 👍👍👍🇺🇸🇺🇸🇺🇸
@@elvisammo no only liquid to gas phase change is endothermic, if the small bottle is so empty it only contains gas no real change will occur compared to the incoming gas pressure when filled. If you get a hose and stick the little guy in an ice bath it will fill completely every time.
I should add I am 99% sure they fill these by depressing the relief valve on the side until liquid comes out. It needs to be upright tho as this ensures not overfilling.
I have had an adapter just like you show for over 30 years. I have filled many propane bottles like you show. People should read the warnings on the bottle that says it is illegal to re-fill the 1 lb bottles and transport them. ** You keep saying let the air out, air is what we breathe. The air we breathe is a mixture of gases, by volume 78.1% nitrogen, 21.0% oxygen, 0.9% argon, and 0.04% carbon dioxide. ** The propane bottles have liquid propane in them that changes into a gas to leave the upright bottle. A propane tank should not have air in it, propane in gas form but not air like we breathe. ** If a tank did get a little air in it, it would not fill right. But the air would bleed out when the bottle is upright and you use it a little or release the some of the propane gas in it very carefully like you show. Propane gas is heavier than air. ** I charged air conditioners since the mid 1960's and had to be careful not to let even a little air from the gauge set hoses into a system. ** Propane like refrigerants increases in pressure when it gets warmer and has a lower pressure when cool. That is why some people say to cool the 1 pound tank. The warmer 20 lb bottle will have more pressure in it than a cooled 1 lb bottle with just a little propane. For each temperature there is a certain pressure. Each different refrigerant has a different pressure temperature table. ** Also people need to know not to over fill the 1 lb tanks! When I camp I use propane from a 20 lb bottle with a hose to my portable Weber grill. There are now refillable 1 lb tanks but they cost $20 to $30. ** The 20 lb propane bottles are only legal to refill for 12 years after the stamped date. The work around is to exchange an old tank at a excange location like Lowe's. You only get 15 lbs of propane in the exchange tank.
They fill better when the 1lb bottle is in the upright position and the larger bottle is inverted. You need the adapter with a 90° elbow to accomplish this.
How long do you use the 1 lbs bottles for, as in for how many refills? Because I wonder what the service life is on those overpressure valves. I’d like to stay on the safe side but still be a cheapskate because those 1 lbs bottles are at least 15 bucks here in the Netherlands.
I got to try the air release first but mine have been filling up to maybe 5 - 10% max! I ran torch for few minutes and it was out! I even been putting my 1lb in the freezer before hand.
Especially if the tank has just a little bit left in it when you release the air what you are really doing is releasing that low pressure after that you should fill up all the way👍👍👍🇺🇸🇺🇸🇺🇸
@@elvisammo Tried again by emptying air first, there was actually very little air left in the bottle and still It filled up the bottle very little with propane. My 20lb tank at least 2/3 full. I decided to empty the air after refill and actually managed to empty the ENTIRE bottle, there was no more air coming out and no mist either. Also strangely enough it didn't smell like propane gas but I opened the garage door to air out anyway and filled it up again, I repeated again and after 3 refills I could feel some liquid in the bottle but it was full at 20% at most! Too much hassle, next time I'll use a scale to see how much I am actually refilling.
at the end of the video you're not letting out air, you're letting out lp vapor. lp is is only liquid because of the pressure in the tank. the "air" will come out until all of the liquid is gone. the reason more liquid fits is because venting the gas causing liquid to evaporate (inside the tank) and cool the tank, the cool tank has less pressure than the room temp white tank so more liquid will flow until the pressure equalizes there's nothing wrong with what you're doing, but this is the same as cooling the tank in a freezer. in other words, you're making room in the tank by venting air, you're cooling the tank and reducing the pressure
Yes. This does the two things that people think works. It combines the two. Freezes the tank and makes room for the liquid. With out the more technical equipment of the filling station! Thanks for the details! I’m close to being technically right maybe.. 🥴
Propane is a very low pressure gas. You would have to do that for something like CO2 or especially HPA, but propane it is no big deal. The weak point is the fill valves. They can fail and when they do it is noticeable as the tank loses weight over storage. Then you discard them. Also the bottom of the propane tank is designed to bulge before any other dimension is altered. If the bottom of the tank is rounded where it can't stand upright, discard it.
The issue is that these tanks are simply not built to the specs required for re-certification- thus hydro testing is largely pointless as no one will do it. Consequently you really don't know what your margins are. Nevertheless they have to be built to operate safely under reasonable conditions and be able to take repeated thermal pressure changes-diurnal, seasonal, etc. What you do want to make sure of is that the tank is not ballooning outwards. Once you see that the tank is done. That is almost always due to overfilling. Propane has many times the thermal coefficient of expansion of water thus the tank fill should never exceed 80 percent by volume. That requirement will be reflected in the net weight stamped on the tank. Incidentally the refrigeration method of refill will rarely if ever reach the design fill point so is a plus for that method. While nowadays I use the Flame King re-fillables I used to use a scale. I didn't bother with refrigeration as it didn't let me fill to the proper levels. There are ways to manipulate the relief valve to insure I get the exact amount of propane. Like everything else there are pros and cons to it. It just depends on how much effort you want to put into it. I personally did not use those small adapters but always used a hose with a dead-man valve so I could keep the tank upright on a scale when filling.
The use of the term "air" for what you are releasing from the can is confusing. If my understanding is correct the pressure is built in the container from the liquid propane becoming a gas as it does so at normal atmospheric pressure at like -44 degrees or something like that. If you depress the valve on a half filled tank it would seem that you are just releasing the propane that has transitioned to a gas. When you stop releasing it the propane that is liquid in the tank will just boil off into a gas to replace what you just vented. The factors regulating the state of the propane (liquid vs gas) are pressure and temperature. You can only fully fill the tank with a liquid if you have a mechanism to allow the gas that is in the take to leave while the liquid is being put into the tank. If you don't let the gas out then the liquid will only fill till it finds equilibrium by compressing the gas that is present in the tank.
Just got a similar device to fill my small tanks. I got it to fill the first time, but the second time it refused to fill... I'll bleed it out and try now.
I wouldn’t leave them in my vehicle if I was stopping long-term, otherwise in the trunk insulated with your stuff, this keeps him cooler, or in a back of a truck insulated from direct sunlight, that should be good enough. That’s how I would do it. There is expansion safety valves on propane tanks that has kept us safe for years.👍👍👍
Hopefully it's not 'air' you're bleeding off, but low pressure gas phase propane. Air in the bottles would actually be dangerous. That's why you never leave that valve open to atmosphere any longer than it takes to disconnect it or bleed off what little pressure has built up inside from warming. Also, you really don't want to 'bleed' a cooled and empty bottle, because it will likely suck IN some air, and you do NOT want to mix it with propane. Moisture makes for rust. As to why the smaller bottles are not filling all the way, it's because the larger tank's pressure has decreased after each fill of the smaller bottle - and there's less pressure when both tanks equalize. So letting off the pressure in the small bottle allows a little bit more to fill it. Learn the gas laws i.e. Boyles' law, Charle's law, etc., to see why this and cooling bottles are the tricks to filling bottles.
Elvis weight your 1lb propane bottle on a postal scale be for and after you fill the 1lb propane bottle,your not getting a full fill of your small bottle. They sell refillable 1lb tanks where tou can unscrew the safety valve some to where you see a white stream coming out of the bottle you'll get a true fill of your small bottle. Just weigh the small bottle before and after,you'll see the way you're doing it it's NOT completely full!
@@elvisammo just weight the 1lb bottle before and after to see,you'll find out the weight of the empty bottle is not 1lb more in weight,scales don't lie!
Hate to tell you but having zero understanding of the dangers of not knowing how much you filled it to is what you have done. Filling these without weighing the end result is wrong wrong wrong. You have potentially left yourself in a dangerous situation and you are completely unaware. Weigh the bottle! Make sure it does not have a total weigh of more than 30 oz then you are doing it right. BTW there is no ‘air’ related to this process- it is either propane gas or propane liquid
Been doing it for years. Can't remember when I last bought a camp cylinder. Keep them coming, Elvis!

WOW, just a few days ago I mentioned refilling these little one pound tanks on a forum and had folks jumping up and down about it, Been doing it for years and pleased to see you doing the same.

I think the "air" you let out is actually remaining propane. When you let some of it out, more liquid propane becomes "air" to fill up the space.

The issue is that these tanks are simply not built to the specs required for re-certification- thus hydro testing is largely pointless as no one will do it. Consequently you really don't know what your margins are. Nevertheless they have to be built to operate safely under reasonable conditions and be able to take repeated thermal pressure changes-diurnal, seasonal, etc. What you do want to make sure of is that the tank is not ballooning outwards. Once you see that the tank is done. That is almost always due to overfilling. Propane has many times the thermal coefficient of expansion of water thus the tank fill should never exceed 80 percent by volume. That requirement will be reflected in the net weight stamped on the tank. Incidentally the refrigeration method of refill will rarely if ever reach the design fill point so is a plus for that method.
While nowadays I use the Flame King re-fillables I used to use a scale. I didn't bother with refrigeration as it didn't let me fill to the proper levels. There are ways to manipulate the relief valve to insure I get the exact amount of propane. Like everything else there are pros and cons to it. It just depends on how much effort you want to put into it. I personally did not use those small adapters but always used a hose with a dead-man valve so I could keep the tank upright on a scale when filling.
The use of the term "air" for what you are releasing from the can is confusing. If my understanding is correct the pressure is built in the container from the liquid propane becoming a gas as it does so at normal atmospheric pressure at like -44 degrees or something like that. If you depress the valve on a half filled tank it would seem that you are just releasing the propane that has transitioned to a gas. When you stop releasing it the propane that is liquid in the tank will just boil off into a gas to replace what you just vented. The factors regulating the state of the propane (liquid vs gas) are pressure and temperature. You can only fully fill the tank with a liquid if you have a mechanism to allow the gas that is in the take to leave while the liquid is being put into the tank. If you don't let the gas out then the liquid will only fill till it finds equilibrium by compressing the gas that is present in the tank.
Just got a similar device to fill my small tanks. I got it to fill the first time, but the second time it refused to fill... I'll bleed it out and try now.
thanks to brandon, I cant afford LP

you know what they say! Let Go Brandon!!!!!!! 😎
Great video Elvis! What's the best way to store those little green tanks in your vehicle and ideas would be appreciated.
I wouldn’t leave them in my vehicle if I was stopping long-term, otherwise in the trunk insulated with your stuff, this keeps him cooler, or in a back of a truck insulated from direct sunlight, that should be good enough. That’s how I would do it. There is expansion safety valves on propane tanks that has kept us safe for years.👍👍👍
Hopefully it's not 'air' you're bleeding off, but low pressure gas phase propane. Air in the bottles would actually be dangerous. That's why you never leave that valve open to atmosphere any longer than it takes to disconnect it or bleed off what little pressure has built up inside from warming. Also, you really don't want to 'bleed' a cooled and empty bottle, because it will likely suck IN some air, and you do NOT want to mix it with propane. Moisture makes for rust.
As to why the smaller bottles are not filling all the way, it's because the larger tank's pressure has decreased after each fill of the smaller bottle - and there's less pressure when both tanks equalize. So letting off the pressure in the small bottle allows a little bit more to fill it. Learn the gas laws i.e. Boyles' law, Charle's law, etc., to see why this and cooling bottles are the tricks to filling bottles.
Elvis weight your 1lb propane bottle on a postal scale be for and after you fill the 1lb propane bottle,your not getting a full fill of your small bottle.
They sell refillable 1lb tanks where tou can unscrew the safety valve some to where you see a white stream coming out of the bottle you'll get a true fill of your small bottle.
Just weigh the small bottle before and after,you'll see the way you're doing it it's NOT completely full!
They are definitely full …can’t fit no more in there for sure. 😎
@@elvisammo just weight the 1lb bottle before and after to see,you'll find out the weight of the empty bottle is not 1lb more in weight,scales don't lie!
You did not check for excessive pressure which can be in an excessive state.
Hate to tell you but having zero understanding of the dangers of not knowing how much you filled it to is what you have done. Filling these without weighing the end result is wrong wrong wrong. You have potentially left yourself in a dangerous situation and you are completely unaware. Weigh the bottle! Make sure it does not have a total weigh of more than 30 oz then you are doing it right. BTW there is no ‘air’ related to this process- it is either propane gas or propane
liquid

Yup we pay for the tank every time.
This shouldn't be done without a scale.
🖖 👍
