Camping cylinders, used to provide fuel for camp kitchens, gas burners and some other equipment, are in most cases disposable. However, in reality, throwing away such wealth is an unacceptable luxury. Not everyone knows that "disposable" cans can actually be refilled quite simply. The main thing is to make an adapter and find (purchase) a large propane tank.
The main difficulty in refilling disposable cartridges is to create an adapter. Fortunately, even a child can build it. For work, we need a pair of clamps, a gas hose, an old burner (such that it has a valve), a lining to the fitting and, in fact, the fitting itself to the cylinder.
First of all, we disconnect the nozzle at the gas burner. We attach the hose to the tube and fix it with a clamp. On the opposite end of the hose we put a fitting, which is also attached with the help of the clamp available in stock. It is he (the fitting) that will be put on a large gas cylinder, and the other end, with a part from the burner, will be connected to the cartridge. Before refueling, the donor balloon must be placed on its side without fail.
Refueling takes only a few seconds. After collecting the entire system together and connecting an empty canister, open the valve and almost immediately screw it back. Before starting refueling, it will not be superfluous to "punch" through the Internet or search for data on its characteristics on the disposable can itself. Namely, how much it should weigh in a tucked state. With the help of the scales, it will subsequently be possible to determine whether the canister is completely filled. So, for example, a container weighing 95 grams after full propane filling weighs 220 grams.
