Propane for Preppers – Part Three

Print Friendly

One of the more frequent questions I get relative to propane has to do refilling propane tanks.  I am not talking about those 20 pound tanks commonly used with backyard BBQs.  Instead, the questions have to do with refilling those ubiquitous one pound cylinders that are used with portable stoves, lanterns, and heaters.

In this next installment of Propane for Preppers, you are going to learn how to refill your one pound propane tanks.  As you will learn, there are pros and cons mostly relating to safety considerations.  The last thing I want, after all, is for you to blow yourself up along with the rest of the neighborhood.

Propane for Preppers Part Three

Propane for Preppers Part Three is the next installment in the series as written exclusively for BDS by my friend Ron Brown, who has taken considerable time to put together a comprehensive tutorial for you.  This is information you need to know and as you will find, Ron explains things with unbeatable wit and humor!

In case you missed it, here is a link to Part One and Part Two.  Otherwise, let us continue on to Part Three.

Propane for Preppers – Part Three

The Economics of Refilling

A store-bought one-pounder is double or triple the cost of a home-filled cylinder.

My propane supplier just now filled our 200-pound tank behind the house. He charged $3.86 per gallon including 3% sales tax. A gallon of propane weighs 4.23 lb. so my propane cost $.91 per pound (3.86 / 4.23 = .91).

A so-called ‘one-pounder’ holds 16.4 ounces (465 grams) or 1.025 pounds (16.4 / 16 = 1.025).

Using these figures, were I to home-fill a propane one-pounder, it would cost $.93 per cylinder (.91 x 1.025 = .93).

Wal-Mart’s lowest-priced one-pounders are $2.90 per cylinder including 8% sales tax.

On this basis, store-bought cylinders are triple the cost of home-filled cylinders (2.90 / .93 = 3.12).

But here’s a worst-case scenario. Another dealer, locally, charges a flat $12 (including sales tax) to refill a 20-pounder, be it empty or almost full. In other words, he’s topping it off for $12.

If you reserve a 20-pounder exclusively for refilling and always top it off when it gets down to 50%, then you’re effectively paying $1.20 per lb. Even so, if you do the arithmetic, it works out that a store-bought one-pounder is more than double the cost of home refilling.


All the propane one-pounder brands I’ve seen (currently on the market in the USA) carry this disclaimer on the label: “Never refill this cylinder. Federal law forbids transportation if refilled – penalty up to $500,000 and 5 years imprisonment (49 U.S.C. 5124).”

Coleman’s statement is even stronger: “Never refill this cylinder. Refilling may cause explosion. Federal law forbids . . . blah, blah, blah.” The explosion bit does not appear on other brands.

Coleman one-pounders sold in Canada and Coleman one-pounders circa 1980 carry softer warnings. In Canada the label says, “Do not refill cylinder.” NEVER is replaced with ‘do not.’ And there is no mention of explosion. The old 1980 label says, “It is HAZARDOUS TO REFILL this cylinder.” [emphasis theirs] Quite different from NEVER. And, again, no mention in 1980 of explosion.

In the business world, these are classic CYA statements (Cover Your Fanny). The propane company doesn’t care if you refill the cylinder. They just don’t want to get hauled into court. So to escape any legal liability they say, “Never refill . . .” That gets them off the hook.

U.S.C. stands for United States Code; ‘49’ is the chapter. You can Google for it. And then argue all day about what it means. Does it apply only to ‘commerce’ and not to private individuals? As a federal law, does it apply only to interstate transportation across state lines? Or does it apply to intrastate transportation as well?

The 49 U.S.C. 5124 statement even appears on Coleman-Canada propane labels. I assume its function is to scare people. I don’t see where it would have any more relevance in Canada than the Canadian age of consent has in the USA. (Raised in 2008, BTW, from fourteen to sixteen.)

Transportation notwithstanding, I strongly doubt it is a crime to REFILL a propane cylinder. If it were, then Mr Heater [20] and MacCoupler [21] and EZ Adapters [22] and CE Compass [23] and Gascru [24] and Schnozzle [25] (all of which are brands of refill adapters) would be accessories. As would Amazon, eBay, and your local hardware store where the adapters are sold.


Cylinder leakage is a legitimate concern.

One-pounders have a Schrader valve as their main valve. A Schrader valve is what you have in your car or bicycle tire. The Schrader valve seat, the seal, is rubber.

Bigger tanks (such as the 20-pounder we’ll use as a source-tank in refilling), employ brass needle valves. Big difference in reliability and life expectancy.

When you attach and detach a one-pounder to an appliance (stove, lantern, etc.) gaseous propane travels through the cylinder’s Schrader valve. When you refill, liquid propane travels through the valve. I’m not sure if that does any harm but I’m certain it lacks any benefit.

Of course, the sporting-goods company wants you to throw out the old cylinder and buy new. As discussed in Part One, brass end caps with O-rings will stop a cylinder from leaking. But if you don’t test the cylinder after refilling, and if you don’t install a brass end cap plus O-ring on the leakers, you’ll be traveling down the road wafting a trail of gaseous propane behind you, extremely flammable stuff.

As the old saying has it, “Your right to swing your fist ends with the beginning of my nose.” Rephrased: “Your right to travel the highway with a leaking propane cylinder ends just before you blow up me and my family.”

Curiosity got the best of me and I cut the top off a one-pounder. You can see the bottom end of the main Schrader valve and a reverse Schrader valve, for lack of a better term, that serves as the cylinder’s pressure-relief valve. The relief valve appears upper-left in the image; it’s barely visible on the outside of the cylinder but inside it is bigger than the main valve.

As discussed in an earlier installment, one-pounders are prone to leaking. I’ve had it happen several times. Please don’t casually dismiss the possibility.

Propane 1 Pound Cylinder Cut Open

So Here’s How You Do the Doin’

First, to paraphrase Mark Twain, there are two kinds of men. Those who learn by reading the directions. And all the rest of us who must pee on the electric fence and find out the hard way. So let’s get to it.

1. Materials. We need (1) an empty one-pounder, (2) an adapter, and (3) a 20-pounder at least half full.

We also need (4) an insulated sleeve to slip over the one-pounder and (5) a brass pushpin, discussed below, with which to release pressure from the one-pounder.

(6) Leather gloves are a good idea to avoid frostbite if something goes wrong. As are (7) safety goggles. Frostbitten fingers are one thing; frostbitten corneas (should you get hit in the face with a blast of liquid propane), quite another.

2. Environment. We need a heavy-duty table (like a picnic table) to work on. Being outside, a ‘floor’ of blacktop or concrete would be welcome. We don’t need a table-leg to sink into mud or soft dirt and dump our tanks on the ground. Oops.

It is imperative to work outside where there is good air circulation (to disperse any puff of propane that may escape as we screw and unscrew cylinders). And to disperse a ‘propane cloud’ should the unthinkable occur.

In 2012, Stanley Johnson (Polk County, Minnesota) had a fatal explosion – it was his wife who died actually, not he – while refilling a one-pounder inside his garage. Propane is heavier than air. It pools on the floor. Outside, Stanley would have had a fire. Inside, he had an explosion.

3. Procedure. Turn the 20-pound supply-tank upside down. The valve where (liquid) propane will exit is then at the bottom. Inside the tank, liquid propane is immediately above the valve. Gaseous propane is at the top, next to what is now the ceiling of the tank.

Propane Tank Refill Adapter

Propane Tank Upside Down

4. Screw the adapter into the supply-tank. This is tricky spot #1 because we’re dealing with a left-hand thread (meaning that, when tightening, it turns counter-clockwise, contrary to ordinary nuts-and-bolts). We snug the adapter tight with a 1⅛” open-end wrench. ‘Snug’ is all we need. It’s the adapter’s rubber O-ring that forms the seal.

5. Screw the one-pounder, the receiving-tank, into the other end of the adapter. (Note that we’re starting with the supply-tank and the receiving-tank at the same temperature.) When attaching the one-pounder, it’s the old “righty-tighty, lefty-loosey” because we’re dealing with an ordinary right-hand thread.

One pound propane tank connection to larger tank

Propane Tank Connection

But it’s really tricky spot #2. Why? Because one end of the adapter has a left-hand thread and the other end has a right-hand thread. If we over-tighten the receiving-end we simultaneously loosen the supply-end.

My solution is to leave the open-end wrench in place to serve as a handle. It’s then easy to prevent loosening the adapter from the supply-tank. The wrench can be removed when we no longer need a handle.

Open End Wrench to Propane Tank

Propane Tanks Hooked Together

6. Once the tanks are hooked firmly together, remove the handle/wrench, tip the supply-tank up on its side (slightly) to gain access to its triangular valve-knob, then reach under there and open the valve full.

7. Wait one minute for the filling to complete. You can hear a hissing noise (for 10-30 seconds) as the transfer takes place but I’ve found that one minute gives better results than ending the fill right after the hissing stops. Five minutes, on the other hand, does not give better results than one minute.

8. Turn off the triangular valve-knob and remove the newly-filled one-pounder. This is tricky spot #3. Turn off the supply-tank before unscrewing the receiving-tank.

I really need to impress this upon you. DO NOT REMOVE THE ONE-POUNDER BEFORE YOU TURN OFF THE 20-POUNDER.

Although I just said it three different ways, one forgetful moment will reward you with a propane cloud – generated by liquid propane, under pressure, gushing out of the 20-pounder. A propane cloud has the potential for a major fire or explosion. One spark at considerable distance – your neighbor lighting his BBQ grill, for example – can do the trick. This is not kid stuff. You are coloring outside the lines here.

I mentioned in an earlier installment that, with today’s OPD valves, if no appliance is hooked up to the tank then no propane will exit the tank even if the valve is left open. Great! HOWEVER, when we remove the just-filled one-pounder, the 20-lb. source tank is still hooked up to an appliance: the ADAPTER.

My fear is that, once you see how easy it is to refill a one-pounder, you’ll lose respect for the potential danger. Just the other day my wife and I saw a woman walk into a telephone pole – ALMOST – while texting. She was coming towards us on the sidewalk but not really paying attention to what she was doing. She stopped with the pole just six inches from her nose.

We laughed out loud. She was horribly embarrassed. She was so distracted by the phone that she forgot where she was walking. Is that so much different than watching the girls sunbath next door and neglecting to turn off the 20-pounder before we remove the one-pounder? DISASTER!

Refilling is both easy and safe IF we stay focused.

Once you’ve launched a propane cloud, BTW, reaching into that cloud to turn off the forgotten valve will produce frostbite. Converting from liquid to vapor (and that’s what the propane is doing) requires heat. Just like when liquid water turns into gaseous steam, heat is required.

Heat. Calories. Your hand will supply calories. And when your hand gives up calories your hand gets cold. Google for ‘frostbitten fingers’ and click ‘images.’ I guarantee it will make an impression.

At this point (assuming you’re still alive and all is well), you’ve detached the one-pounder with 280 grams of propane inside. That’s 60% of the one-pounder’s 465-gram capacity.

Your results may vary. The 60% figure is ‘typical.’ I’ve gotten everything from 54% to 75% using this same procedure and I’ve given up trying to understand the variance.

9.  If you’re satisfied with a 60% refill then you’re done. But most of us, I suspect, would rather have 100%. No problem. Here’s how:

First, release some pressure from the receiving tank that we just filled to 60% (the one-pounder). Do this by pushing in on the one-pounder’s Schrader valve located top-center on the cylinder. It’s like letting air out of a tire. Depress the valve-stem for 5-10 seconds.

Do it outside. Hold the one-pounder upright. That will release gaseous propane from the top of the cylinder. Holding the one-pounder upside down will release liquid propane. Not good.

Use a brass rod to depress the Schrader valve. This is important. Brass is non-sparking. A ‘lift wire’ for use on your flush toilet is just under ⅛” in diameter plus being brass. Perfect.

Lift Wire

Releasing Propane Pressure After Refilling

In this procedure, you’re not really ‘releasing pressure’ per se. Rather, the Schrader-valve pressure-release chills the receiving-tank. You can feel in your hands the one-pounder get cold. The colder tank temperature equates to lower pressure inside the tank; pressure varies directly with temperature.

10. Immediately screw the one-pounder back onto the adapter. Don’t linger. Slide the insulated sleeve over the one-pounder. You just took steps to make the one-pounder cold; now keep it cold.

My insulated sleeve is a homemade cardboard cylinder covered with three layers of bubble wrap. The sleeve’s bottom-end was made by winding an inch-wide strip of bubble wrap into a ‘wheel’ (slightly oversize), then shoehorning the wheel into the hole in the bottom of the cardboard cylinder.

Even before adding the insulated sleeve, there’s precious little clearance between the side of the one-pounder and the tabletop. With the sleeve in place, all clearance disappears. Hence the 20-pounder must perch fairly close to the edge of the table so that the one-pounder (and sleeve) can hang completely off the edge.

Chill the propane receiving tank

11. Next, repeat steps #6-8. That is:

(6) Open the valve on the supply-tank.

(7) Wait one minute for filling to occur.

(8) TURN OFF THE SUPPLY TANK, remove the insulated sleeve, and unscrew the receiving-tank.

At this point you can expect your receiving-tank to contain somewhere between 435 and 480 grams net. That’s a range from 94% to 103% of the one-pounder’s 465-gram capacity. Gee, 100% has a nice ring to it. (Your results may vary.)

If you do the chill-thing with the Schrader valve but, in the next step, fail to use an insulated sleeve, you can expect 325-400 grams net in the one-pounder. That’s 81% to 86% of its capacity. (Your results may vary.)

So . . . can you use this technique to top off your not-so-well filled one-pounders? That is, can you chill the cylinder via the Schrader valve and then keep the cylinder cold in an insulated sleeve? Can you do that with a one-pounder now filled to 60%, say, and bring it up to 100%?  Can you? Yes.

12. Assuming, again, that you are still alive and have survived step #8 (twice), weigh the newly-filled cylinder to check for over-filling.

A brand new one-pounder holds 465 grams net of propane. The tare weight is 400 grams. That’s a gross weight of 865 grams or 30.5 ounces. If your cylinder is overfilled, you can burn off the excess with an appliance (stove burner, for example) or keep poking the Schrader valve with your brass rod – psst – until the cylinder is merely full, not overfull.

If you use the psst method, do it outside.

In a later installment we’ll discuss the dangers of overfilling and the necessity of leaving some headspace in the cylinder. For the moment, please take it on faith that you DO NOT want to overfill any propane cylinder.

13. Immerse your newly filled one-pounder in a basin of water and check it for leaks.

If it blows bubbles from the main valve, you can poke at it with your brass rod and attempt to get the valve seated properly. Do it with the cylinder upright so that gaseous propane escapes, not liquid propane. Failing that (and, to be honest, the brass-rod thing has never worked for me), install a brass end cap plus O-ring as discussed in Part Two.

If you have no way of capping off a leaker, install it on a stove burner (or other appliance) and run the device until the one-pounder is empty. Do not store propane in a leaking cylinder. You don’t need neighbors complaining about the funny smell or the noise of an explosion. You know how picky neighbors can be.

If the one-pounder blows bubbles from the safety valve, don’t even try and fix it. Just use up the gas immediately and dispose of the cylinder.

Theoretically you could pull-and-snap-release the stem of the safety valve with needle-nose pliers in an attempt to seat it properly but that’s steel-on-steel; non-sparking it ain’t. And if you’re really aggressive, I’ve heard tell of people pulling the valve stem right out of the cylinder. Woot, woot!

Yanking the valve stem out of a full one-pounder would constitute a genuine emergency. Should it happen, hold the cylinder upright. If you turn it upside down, liquid propane will surge out; a propane cloud. And let’s hope you’re outside when it happens. Everything you can think of produces sparks. Electric motors when they start. Light switches. Uncle Harry when he lights his cigar.

But, hey, if the one-pounder is full and doesn’t leak and you’re still alive and the barn didn’t burn down and your nose hairs didn’t get singed and you don’t have frostbite . . . then you can swagger along home with bragging rights, eh?

Plus you saved $1.97. That’s my kinda afternoon.

The Final Word

Everyone likes to save money, right? It only makes sense, really, to save what we can where we can.

Refilling on pound propane tanks can be a great money-saver and convenient as all heck as long as you adhere to the utmost in safety precautions.  On the other hand, if you are not mechanically inclined and do not have an outside area in which to work, refilling-one pound propane tanks may not be for you.  It may, in all honesty, be fatal.

I do not mean to scare you; only to exercise diligence and caution, okay?

Coming up in part four of Propane for Preppers is a discussion of refilling 20-pounders as well as the long-term storage of one-pounders. We’ll also cover carbon monoxide and oxygen starvation. Should be interesting, no?

Propane for Preppers – Part Three — 24 Comments

  1. I have done this a few times.
    Put the one pounder cylinders in the freezer for half and hour before refilling them.
    This will close to the 100% fill rate.

    • Thanks for your interest but I strongly recommend AGAINST chilling a one-pounder in the freezer. I have used the freezer method myself and it has always resulted in overfilling. Granted, it’s what you’ll see most often on YouTube but I personally believe that the people recommending it are wrong. Gas (headspace) in the cylinder can be compressed. Liquid cannot be compressed (not liquid water and not liquid propane).

      Let’s say you fill your one-pounder FULL (leaving no headspace) then leave it in the parking lot in the back of your SUV in the summer with the windows rolled up. The cylinder gets warm. The liquid expands. The cylinder vents some propane through its safety relief valve but then ruptures if the valve is not up to the task. Tell me it ain’t never gonna happen.

      Installment #5 of this series will discuss the dangers of overfilling in more detail.

      • The “chillin'” method is what was recommended by the manufacturer of the filling device that I bought from Cabela’s MANY years ago. It works well. I don’t put mine in the freezer, I just sink them in an ice chest full of ice for about 15 minutes before filling.

        • Regardless of your refill method, it is most important that you check, with a scale, the weight of your one-pounder after refilling. Otherwise, you are just guessing. I hate to be hardnosed about this, but propane is not something to estimate or guesstimate. I’ve come to have a very healthy respect for the stuff.

          Just because you’ve done it for years without checking on a scale and without incident is not proof of its safety. After all, you might cross the road without looking for years. And get away with it for years. But that doesn’t mean it’s safe to do so.

          I use an inexpensive plastic scale (Salter brand) with a 0-7 lb. weight range capability. As mentioned above (in Part 3 of Propane for Preppers), anything above 865 grams or 30.5 ounces gross weight indicates overfilling. The excess needs to be bled off. If you’ve been estimating all along, please buy a scale and check out your actual results. You might be surprised.

          This really is important.

  2. Outstanding article! One of the BEST, I’ve ever read or seen on any preparedness website. Well Done! (and thank you!!)

  3. Interesting read for sure, thank you Ron, I really enjoyed it!


    As you said: “On the other hand, if you are not mechanically inclined and do not have an outside area in which to work, refilling-one pound propane tanks may not be for you.”

    This should cover 80% of the population.

    I’m easily capable of refilling the cylinders, but why?

    A new one pounder from Wally is $2.97. If as you said you save $1.97, there is a difference of One dollar. To save the one dollar, you need to buy an adapter (Sears $ 8.95) a cap and O-ring if there is a leak (about $3.65), and a scale to check proper fill. And of course there is a question how much your time is worth.

    So in recap: 80% of the population should not try this, and for the other 20% this is not a saving.

    It is still a fun read!

    • Thanks for your input, Magyar, but your 80% figure should, in my mind, be more like 10%. For example, I know a lady who was brought up in a house full of servants. She literally had never changed a light bulb before she was married. She laughs about it today, telling how she sat on the bed and cried when her new husband forced her to do it. In my mind, SHE is the kind of person who has no business refilling propane one-pounders.

      And I agree, the cost savings are small. TODAY. But there’s comfort in knowing how to do things. I no longer change the oil in my car, for example. But I’ve done it and I know how. And if you take that little capability and multiply it by a hundred – or a thousand – other things that you know how to do, it gives you some independence. When TSHTF, I would prefer to feel I can cope as opposed to feeling helpless.

      Being able to refill a propane one-pounder could, in the right circumstance, be priceless knowledge. I have a book out on Amazon (“The New 2000-Hour Flashlight”) where one reader commented, “I live in South Florida and wish I had had this information when after Hurricane Wilma we were 3 weeks without electricity.” THAT is when you need to know how to refill propane one-pounders. TODAY, I agree, saving $1.97 is a “who cares?” But THEN, it means you’ll have light; it means you’ll be able to cook supper. I guess maybe it’s a prepper thing

  4. Thanks for the article. I have the adapter for emergencies, but have never used it. I feel much more confident about it now. Thanks a TON!!!!!!

    • Thanks, Kevin, for your interest. The fact that you have an adapter? Super! Because there’s no substitute for it. In fact, supercalifragilisticexpialidocious! But I would urge you to use your adapter and actually refill a one-pounder. As I have said so many times, like sex, reading about it and doing it are two different things.

  5. Thanks for your interest, Mark, and for your time to write up your remarks. In fact, I have a Worthington one-pounder setting on the desk beside me as I write this. Under HANDLING AND STORAGE the label says “4. Never refill this cylinder.” If your Worthington cylinders do not say that, then it is most likely that you are looking at older cylinders. You yourself may have owned them for several years OR they may have been setting on a store shelf for several years. To the folks who rebuild antique cars, this would be called “new-old stock.” Picture a car headlight, brand new, still sealed in the factory box. But manufactured in 1921. Mom-and-pop hardware stores are full of new-old stock. Propane one-pounders are no exception. I assure you that Worthington one-pounders made and sold TODAY are labeled, “Never refill this cylinder.”

  6. I have been doing this for at least 25 years. It is easy. I reuse the cylinders for my propane fogger. I just fill them at equalized pressure and keep another on hand when it runs out. (I don’t worry about getting them filled 100%)

  7. Electric fences were not around in Mark Twain’s day. The quote came from Will Rogers

  8. I have always kept a small supply of non leaded gas with stabilizer and changed it out yearly. It is in sealed DOT approved containers tightly capped and stored in a large plastic covered 4 x 2 foot snap lid also sealed to keep out rain etc. Why with all my care to keep my emergency fuel ready do I lose a portion of they fuel to evaporation. Any ideas on keeping this gas whole.
