I have used about half a dozen of the gas cans i refilled and I'm still alive with no issues.
I have just refilled them all. All filled easily, but one wouldn't fill more than halfway, so put it in the freezer for half an hour and then it filled up.

I can understand people being worried about the pressure, but the thin plastic tube that connects the large donor propane tank to the small coleman cans isn't splitting or bulging so thats good enough.

Hi, Coleman C500 canisters are steel not aluminium.
They rust in the top.
Plus test with a magnet, it sticks anywhere on em.

This is it, just shake/ warm the can, take off any wetsuit and you can empty it.

Why would anyone even consider disposing of a 25 % full gas cartridge ? You just use it until it's almost empty and then just place the canister in a bowl of hot water or use a USB heater to use the remaining gas. I'm truly flummoxed 🤔

Each to their own... But it honestly only takes a matter of minutes, and allows you to reclaim the 25% of gas in each can that would otherwise be thrown away.

I personally cant see the point of getting the dregs out of a almost empty gas canister. Much easier just to buy a fresh new one for how little they cost.

I'm all for saving a bit of money here and there and don't want to piss on your parade ! However, this sort of practice could easily lead to disaster for anyone not fully aware of the risks. Even with all the info already posted, there will be people on here that don't fully understand what they are doing. I'm not saying that it can't be done, because obviously it can, but maybe this sort of thing shouldn't be advocated on a public forum without some form of legal disclaimer. Do the canisters not actually state - Do Not Refill ?

Does your adapter have any means to regulate pressure, ie a screw or valve built in?

If not... Just be careful running the stove at full bore when on propane. The extra pressure of propane could literally spurt liquid fuel out everywhere, ie all over a hot stove.

I have found the adaptor to connect my stove too
I have two, but one won't seal, but an additional O ring would sort that if needed.

900g is about right, I've had them over a kilo without any issues. They have a pressure releif valve so you shouldn't be able to blow one up.

I do have a few coleman 1lb bottles so I can have a dabble with them.
I have the adaptor, but it isn't as straightforward as you have to unscrew to weigh it.
Can anyone tell me the weight of a filled coleman 1lb bottle...
I have marked the empty can with 421g, so about 15oz, and the full bottle should have 1lb of gas in it, so about 2lbs (32oz, 910g) full.
