The Polish-made camping gas cylinder GZWM Camping Сylinder BT-0.5 was purchased with the expectation of using it as a backup gas source. Or, if necessary, as a gas source for supplying a gas burner or gas lamp for a cylinder of the European threaded Epi-Gas standard.
Camping gas cylinder GZWM BT-0.5, adapters for filling the cylinder at gas stations and Epi-Gas gas burners.
The inability to precisely control the flow rate and the remainder of the gas in the main five-liter gas cylinder, which is constantly used for cooking or heating in cases of outings by car, made us think about acquiring a backup gas source. As a result, the choice was made in favor of the GZWM Camping Сylinder BT-0.5.

Workmanship of a gas cylinder GZWM BT-0.5 liked. The operation of his crane is very soft, without any step differences, which allows you to smoothly and with good accuracy to regulate the power of gas supply. In the transport position, the external thread of the valve is protected by a plastic cap. The gas bottle valve is equipped with the left-hand male thread G 3/8 LH, which is not very common and popular in our area.
Therefore, in order to ensure the possibility of refueling it at an automobile gas gas station, an adapter for a thread of standard W21.8 was additionally purchased&# 215; 1/14 LH. And for the possibility of using a cylinder to power a gas burner or gas lamp for a tourist cylinder of the Epi-Gas standard, another adapter.
Connection to a tourist gas burner or gas lamp occurs as usual. The only inconvenience is that due to the shape of the GZWM BT-0.5, its use with a burner that does not have a hose and is wound directly on the cylinder will be somewhat difficult. You will have to come up with some kind of stand or extensions to ensure sufficient stability of the dishes on the burner, while boiling water or cooking.
Use of the camping gas cylinder GZWM BT-0.5 in hiking trips.
Judging from the point of view of weight and dimensions, the use of a camping gas cylinder GZWM BT-0.5 in hiking trips would be hardly advisable. It loses to one large standard cylinder at 450 grams in size and only very little, by 50 grams, exceeding the volume of refueling gas. And two cylinders of 450 grams, slightly outperforming them, loses outright by volume of gas.
