Flame King 1LB EMPTY Propane Cylinder Tank – Refillable – Reusable – Safe and Legal Refill Option – DOT Compliant – 16.4 oz for Camping, Backpacking, and Hiking, Green

Updated review: I bought this tank as a spare to go along with the refill setup that includes a tank. When I tried to fill this tank, I was not able to get it to take propane. I assumed it was a defective tank, and reached out to Flame King for guidance. They replied within a couple of days and asked me to check the refill adapter to see if there was a blue plastic sleeve and o-ring on the center stem. Sure enough, there was and once I removed those, this spare tank connected properly and I was able to refill it without issues. Turns out, the tank cylinders have this blue plastic sleeve insert with an o-ring at the base. These will sometimes come off - I assume due to built up gas pressure. Slide them off of the refill adapter, drop the o-ring on top of the tank valve opening, and press the o-ring down into the opening with the blue plastic sleeve until it is flush with the valve. Easy-peasy! I added a couple of photos to show what I’m talking about. All-in-all, these tanks are great and kudos to Flame King for their quick assistance!

These things are great. I have 6 of the greens ones and bought this blue one for my torch guns. Was missing the 2mm (5/64") Allen Key on this one and two green ones. It just had the tape but I have 4 others from the green bottles I purchased. Refill them with my 20lb tank to be cost effective of about $1 per fill compared to $5 per store bought can.

These seem to be quality built and perfect refill bottle. Easy enough to use, do the job. A little more expensive than I think they should be, like everything I guess, but ise them a few times and save money. I’ve always just re-filled store bought cheaper ones just fine. This is nicer, and I like the drain -off valve style to help relief of pressure while you fill.

works great and you can use any refill adapter...I bought a few of these and sometimes there is no allen key with the tank...you might need to buy your own 2mm allen key if it is not included as it is supposed to be...but these are easy to fill up...you need to turn the large tank you are filling from upside down and keep the small tank you are filling upright...use the allen key to open the release valve on the small tank so the air pressure can escape while filling the tank...when the white propane vapor begins shooting out of the release valve on the small tank, the tank is full and you immediately close the release valve with the allen key...best to leave the key in the release valve until you are finished ...obviously you want to do this process away from any flame or spark and in a well ventilated area...outside is best..also, it is wise to make sure both tanks are roughly the same temperature...if the small tank is a lot colder than the big tank containing the propane, you might fill the small tank too much because if it is really cold the propane will condense more as it fills...then later when it warms up it will expand and potentially bulge out and deform your tank...which could lead to a much bigger problem as you might imagine...in fact, it is even advisable not to fill the small tank if either tank is very cold, as you'll run into the same overfilling scenario once the small tank is brought into a warmer environment after being filled while either tank is very cold...I keep both tanks in a heated shed/garage for several hours before taking them outside to refill the smaller tank when I'm refilling during the winter months...warmer months don't require any of these refilling precautions, unless for some odd reason you keep your big tank and/or small tank in a freezer...these refillable tanks do not have a pressure release valve built into them that will automatically release pressure if you accidentally overfill the tank...if you are confused by my precautions above, just remember not to refill the small tank if the small tank is really cold (like you left it outside and it is winter cold when you go to refill it) or if the propane in the big tank is really cold (like the big tank was sitting outside in winter cold when you go to use it to refill a small tank)...will it cause an explosion if you do this? probably not the first time, or second time, or third time....but it certainly could at any time...so just be careful

I absolutely love the concept of refillable 1 pound propane tanks do not get me wrong. In fact, I have bought almost ten of these 1 lb tanks so that I would never have to use a disposable 1 pounder ever again. Tremendous waste and they can't even be recycled because it's "too expensive". All that steel going to waste in some landfill.. Just the thought alone makes me sick. As someone who uses quite a bit of propane regularly, I was very relieved and happy to discover this product. I was in love with this product until I had not one, but two tanks fail rather catastrophically on me within a week of eachother. They were almost brand new too, not more than a month old. After refilling them when disconnecting the tanks from the 20 pound tank as I was unscrewing the 1 pound tanks the same thing happened both times: the entire contents of the tank escaped when the valves failed. ALWAYS REFILL PROPANE TANKS OUTSIDE. The parts get absolutely freezing cold during the gas transfer due to the physics involved which is why you wear gloves when doing the refill, and if I hadn't been wearing gloves I am sure I would have done serious injury to myself by frostbite. As I unscrewed the 1 pound tanks, a couple rotations in and freezing liquid propane began spraying out everywhere. Reacting quickly I shut off the 20lb tank and brought the tank out to the middle of my driveway and set it down a safe distance away from where I had been doing the refill. The entire time propane shooting out the top like a geyser. I knew it was not coming through the bleeder valve because the gas was escaping far too quickly and was shooting straight up which isn't the direction it sprays when exiting the bleeder valve, which is designed to shoot gas out to the side... I then found the reason why it was escaping so violently when I inspected the refill adapter still on the 20 pound tank but the valve on the leaking tank was frozen to the adapter... That's right, the valve from the refillable tank was stuck to the refill adapter which was still screwed in to the 20 pound tank. I don't know if it stuck to the adapter because it was like 30 degrees outside already + the tanks always get super cold during refills as the gas flows from tank A to tank B, or if it was my use of a standard propane refill adapter instead of using the expensive Flame King brand refill adapter, (which costs $50 vs. the $8 ones commonly used that one can purchase at Walmart or on Amazon/eBay), all I know for sure is that these experiences have left me wary of these particular refillable propane tanks. Bear in mind also that I had filled these tanks dozens of times the exact same way with the exact same refill adapter without ANY problems. So I'm definitely going to look in to another brand of refillable tank. Edit : June 21 2019 had another tank fail on me, leaks propane when I unscrew the torch or whatever’s attached to it, it remains leaking fuel until something else is connected all the way but as soon as the seal on the threads loosened propane emerges from the bottle. It’s nothing like Aladdin’s genie coming out of the lamp, its a liability and now I’m having serious doubts about whether or not the remaining 3 good tanks I have are going to fail too. My faith in this product is has taken a downward dive and I keep wondering how long I can use the positive environmental impact as an reason to keep using a product that has such serious safety flaws. Around a 50% fail rate out of the half dozen to dozen of these or so I have bought.

I used this all the time. I don't even fill it up all the way with the release. Great for dab smokers. I still use it for other things.

Got these for camping, specifically for Coleman lanterns. They fit in the base just like the disposables, and of course being refillable they are much cheaper to use over time. Easy to fill with the Flame King refill tool.

Valeu.ok

Great product

Pretty simple to refuel. Looks to be of good quality
