Flame King 1/4-lb Empty Refillable Propane Cylinder Tank - Reusable & Transportable - Safe and Legal Refill Option - UL1769 Listed Valve

I didn't know anything like this existed until I was searching for safely refillable 1lb propane tanks for a small heater and stumbled across it. I need a torch at work occasionally but even with myself and a couple others using it, a single 1lb tank has lasted me a few years at this point and the tank often gets in the way of what I'm trying to do. I figure this tiny guy with a smaller torch head would be exactly what I need, and so far so good! Filling was pretty easy although I had to modify my adapter (Mr. Heater brand) because it had an alignment pin that didn't fully seat into the tank, and wouldn't let the gasket seal. I just trimmed the end of the pin and continued, no issues at all.I bought the little Bluefire self igniting torch head that someone else in the reviews posted a picture of, and I'm not completely happy with its performance (the adjustment knob is weird) but the size is perfect for this tank and I think the horizontal orientation will give me better access too. About to order a second one of these and try a different head for a fire pit torch at home.Added a picture to show size differences.

Perfect size. The bleeder screw on the side gives you a full fill every time.

Worked excellent!

Very convenient for a small torch. I carry it in my tool bag. Easy to fill. Good size.

Great little bottle for copper sweating work.

I do pyro for a living. This bottle being so small and light is amazing for when we do hand light shoots!It is light weight but has plenty of fuel to do a decent job with a torch.It is so simple to refill this tank! All of my co-workers love it and said they will be getting them as well.I only have one, and regret not getting 2. Only reason being that they are so small and light that it would be nice to have one for backup just encase.But these things are amazing!Costing me pennies to refill and being so handy. I can not recommend these enough.

This cylinder used with a small torch head like the BernzOmatic Basic Use UL2317 Brass Pencil Flame Propane Torch Head (which is surprisingly amazing) is absolutely wonderful. Refill from any propane tank, even a 1lb cylinder. The only safe type of refillable small propane cylinder. Because these have a small vent, when filling they fill quickly (because of the tiny vent) and give a clear indication when filled to safe capacity. Just a reminder, do not believe all the stuff you read about refilling your old non-refillable bottles. All the web instructions will result in a dangerously overfilled cylinder with no expansion space. And there is no way to check the fill level without tediously filling a little way, weighing, filling some more, and finally venting excess, wasting propane. Toss your old bottles.

The valve seal failed after the second refill, and propane squirts from the threads when you attempt to attach any accessory. This seems to be a known and frequent issue, as customer support mailed me a repair kit immediately. I was very disappointed to have to repair a virtually brand-new tank after only a few uses.
