When there is a pressure difference between the two tanks, the higher pressure tank will force propane to move to the tank with the lower pressure until the pressure in both tanks equalizes. To help this along, leave the Larger Propane Tank in the sun to warm it up and raise the internal pressure AND cool the 1 pound Propane Cylinder by placing it in a cooler environment such as inside a freezer, refrigerator, ice cooler or at the very least, in the shade which lowers the internal pressure of the bottle.
In order to know how much propane you have in the bottle once it is refilled, you have to know the weight of the empty bottle prior to filling it. We use a Kitchen Scale for this step. Kitchen Scale. When you connect the Propane Refill Adapter into the valve of the larger tank, remember it has left-handed threads so turn the adapter to the left to tighten. You may need to use a wrench to get a snug fit but firm hand-tightening with a pair of Work Gloves has always worked for us.
Propane Refill Adapter. Just screw the 1 pound cylinder to the Propane Refill Adapter being careful not to cross-thread! On a related note, these adapters make awesome camping gifts and are especially nice as inexpensive stocking stuffers at Christmas time! As a side note: Propane Refill Adapters are some of the most popular gifts given to campers during the holiday gift-giving season.
There is nothing worse than telling your guests you forgot you used your home tank to refill your camping gear and you begin frantically searching for the nearest propane refill near me that is open on a Sunday afternoon in order to finish cooking the hamburgers! To avoid triggering the sudden lock out, just open the valve much more slowly at first. There will be a point where there is enough pressure in the little bottle to keep the safety valve from closing, then you can fully open the large tank valve.
We usually get just under 1 pound of propane in a refilled cylinder which is well within the safety limits of the max-rated capacity of the cylinder. Unscrew the 1 lb propane refilled cylinder from the Propane Refill Adapter and replace its plastic thread protector cap to safeguard the threads. Now, remove the adapter from the larger propane tank by turning the Adapter to the right remember these are left-handed threads. Note: When people consider how to store propane tanks, they usually protect them from being dented but they often neglect to protect the threads because it is so easy to misplace the caps.
Your camping propane cylinders will last much longer if you cap them during transportation and storage. To ensure you have not exceeded the max-rated capacity of the 1 lb cylinder, use a Kitchen Scale to weigh the refilled cylinder and calculate the net propane weight by subtracting the empty weight from the new refilled weight. Use a soap that has no phosphorus which attacks copper and brass.
Now you are done and ready to use your refilled camping propane cylinder with some totally cool gear … check these out! Dawn Dish Soap. Laws vary by jurisdiction so check with local authorities to see if propane cylinder refilling is legal in your area.

Most people use 1 lb Propane Cylinders to provide energy for cooking food on their best camping grill stove. We have used these cylinders with camping lights and other types of camping equipment too. An explosion caused by the rupture of a DOT 39 cylinder due to refilling was reported in Polk County, FL in , killing the individual and injuring her husband. If this is so illegal how come its so easy to get a refill adapter from Amazon? I mean, it was very easy, no warning anywhere And came with this card as well.
Don't get me wrong, i absolutely understand there are major dangers when handling combustible gases but my question is really trying to fig out why its so damn easy to get one if so damn dangerous..? But nope! There are def comments dating just a few months back. Reply 5 months ago. Check your DOT regulations! Saves time by changing bottles less often! Propane handling and plumbing takes a licensed professional, not a DIY situation!
Reply 1 year ago. I'm with you. Another post says use the refillable kind. I'm going to treat myself with the ones that somebody else makes. Of course I don't use a whole big lot of them anyway.
This looks like a great way to save money so you have it to spend at the hospital after this thing blows up in your face. You pay to play. Walmart has best prices. Reply 3 years ago. I have been refilling disposable cylinders for over 30 years for personal use without so much as an incident, much less an accident. Ppl blow them selves up because they dont know what they are doing or use improper equipment. Refilling cylinders is perfectly fine doing it the correct way.
All though refilling a store cylinder I would not do more than once or twice. They are not made to withstand repetitive pressure. Air gas used to carry them.
In the US this is a crime. Hey friend. You're using a 20 lb propane tank to fill a 1 lb propane tank This is why you can magically fill 20 1lb tanks off of your 5lb master. Reply 3 years ago. I like to get my small tanks cold before i fill them Reply 2 years ago.
Hi, I see this post is about a year old. If you don't have an answer, this may help with your question. Thanks for sharing. I have an electric one. And I'm completely satisfied with its work. It's very fast and not expensive. Plus, they helped me with all the settings.
Valid Concern 1 Vented propane is flammable and is a hazard once it's out of the tank. It's more of a hazard than you might think because once it's out of the tank it mixes with oxygen in air. Rather than the calm flame you see in a stove or lamp it can explode as it burns all at once.
No one has been able to find a photo of a failed tank because there's a safety pressure-relief valve to vent it if need be. The tank itself will never fail. Maybe if you remove the safety valve and replace it with a bolt. Somewhere around a thousand PSI. The pressure of propane vapor a gas over some amount of pure liquid is a function of temperature. There's a graph.
In the tank the molecules of propane go back and forth between the liquid and the gas. There's a balance reached between the evaporation and condensation rates. The evaporation rate depends on temperature but the condensation rate doesn't so the balance depends on the temperature. The warmer it is, the higher the pressure of the vapor. If there is any amount of liquid and any amount of gas, that graph is obeyed. Nothing you can do will change the vapor pressure.
It's set to a quite high pressure. It's there to stop the tank from rupturing. It's a steel tank. That pressure is high.
It's somewhere around PSI. That's something like 25 bar if you're looking at the vapor pressure graph. Put the tank in boiling water and the pressure will want to rise to double that. The valve should open to prevent that. The tanks are required to have a minimum burst pressure of PSI so they are actually designed somewhat higher. Call it PSI. There's a wide difference between those pressures. These tanks are meant to be discarded after a single use. They aren't meant to open and close repeatedly so when they do open they have a closing-failure rate.
Over time a small leak can release the entire contents into an enclosed area like your trunk or a storage cabinet and you're facing Valid Concern 1.
I don't have the complete data on the physical properties but Wikipedia says that the volume wants to expand 1. Lasts forever and so cheap to refill. Last year I used it for my Coleman 2 burner stove and lantern. Rather than the stansport tree or equivalent, I just bought a splitter and hoses for those times I am running both.
Late last year I added a little red campfire to my gear and use the tank for that as well. I have been using a 1 gallon. Also use it when camping from my truck. When I do fill it up the person filling it always has to comment: Oh…what a cute little tank. Wow, I wish I could afford to go camping enough for my 16 oz disposable propane tanks to become a major expense! Also part of the reason the little propane tanks last longer for me - in addition to not being able to camp as much as I would like - is that I will sometimes cook on a grill, over the fire pit or using my alcohol stove.
I enjoy the variety of cooking types as well as having more options. There is prison time and a huge pentalty behind this. These cylinders are not considered recycleable as they are never fully empty of flamable, potentially explosive gasses, but rather are considered hazardous waste, which is why I hate them. Having said that it is a common thing for people to refill these canisters using those cheap bottle adapters from Amazon, Walmart, or any of countless vendors. If we have any attorneys here it would be a good thing to chime in and clarify this point.
Now assume you DID refill one, and transported it, and an accident happened where say a tank blew up in the back of your truck.
