Comparison Fire-Maple Fuel 0.5 vs Primus Summer Gas Cassette

— Gas bottle. Tanks designed to store gas, usually liquefied. Such storage implies a rather high pressure inside, and also does not allow the slightest leakage, which puts forward increased requirements for the reliability of the tanks.

— Fuel tank. Vessels for liquid fuels such as kerosene. In fact, they are ordinary metal flasks with corks or twists (it is undesirable to use plastic due to the accumulation of a static charge when the liquid rubs against the walls). Unlike cylinders, they are usually supplied empty; you need to buy and fill fuel into a flask yourself.

Method of connecting the cylinder with the burner. This is one of the main criteria for choosing a gas cylinder: the type of connection must match the one provided in the burner.

— Threaded (epi-gas). A variant also known as "European carving". A classic threaded connection, characterized by good reliability and allowing you to remove the cylinder before the gas supply is used up.

— collet. Cylinders with such a connection are also called stock, fitting, and colloquially — "dichlorvos" (because such a container resembles an aerosol can with a spray cap removed). A thin tube (rod) is responsible for the connection, clamped in the collet during installation. This option is popular mainly among tourist gas stoves, which have a recess in the case for a cylinder — if the cylinder is located remotely, the connection would not be very reliable. The cylinders themselves often have thinner walls than other connection types, requiring care in handling.

— Valve (Easy Click). Type of connection used mainly in Campingaz and Coleman burners. This mount is easier and faster to connect/disconnect than a threaded mount, while being considered more secure and leak-proof.

— puncture. In accordance with the name, with this connection, the cylinder shell is pierced. Such tanks are intended mainly for domestic use —...at picnics, summer cottages, in long-term camps, etc. This is due to the fact that the cylinder cannot be disconnected from the burner until the gas is completely used up. On the other hand, puncture models are extremely simple and inexpensive.

The same type of connection from different manufacturers may have different sizes and design features. Therefore, when buying, it is advisable to specify not only this parameter, but also the compatibility of the cylinder with a specific burner model (especially if the burner and tank are from different manufacturers). Also note that for tanks for liquid fuels (see "Type") the type of connection is not indicated at all — they are usually made for stoves of a particular brand.

The weight of the fuel filled into the cylinder, excluding the tank itself. Knowing the approximate fuel consumption in the burner, this parameter can be used to estimate how much the reserve in the cylinder will last. The weight of the tank itself is rather small compared to the weight of the fuel, and can usually be neglected when calculating the total weight of the luggage.

The nominal volume of the tank, in fact — the amount of fuel contained in it. On the practical side, this parameter is relevant primarily for flasks for liquid fuel (see "Type") — for gas cylinders, the weight of the gas filled inside is more important. It also allows you to estimate the approximate dimensions of the cylinder / flask.

Burner models for which this tank is suitable. This information can greatly simplify the choice: for a compatible cylinder, there is no need to specify the type and features of the connection. And in the case of fuel tanks, this parameter is generally the only one that determines compatibility.
