What this listing puts on record

A 227 g butane cartridge, stated to attach and detach without losing gas, stated to cook for up to 3 hours or to prepare up to 8 meals, and stated to meet EN 417:2012. The maker asks in its first bullet that you follow the operating instructions of your own appliance.

Two fittings, one listing

The title names the MSF-1a bayonet connection and says the cartridge suits stoves and appliances with a bayonet valve. A bullet repeats MSF-1a. The last bullet then calls these screw cartridges with a standardised 28 UNEF thread.

Both statements are printed by the seller. They do not describe the same connection, and a stove takes one connection. That is not a detail to weigh against the price: it is the entire question this family exists to answer, and the listing answers it twice, differently.

For that reason this page points at no stove. Every other cartridge here that names a fitting is linked to the stoves whose own listings name the same one; this one is linked to none until the wording agrees with itself.

The run time nobody else gives

Up to 3 hours of cooking, up to 8 meals. No flame setting is named, no appliance, no pot. It is still the only duration published anywhere in this family, and an unqualified figure is at least a figure — as long as it is read for what it is.

Before ordering

Ask the seller which connection the cartridge actually carries, and check the answer against the fitting your stove manual names. Use, storage, carriage and disposal of a pressurised cartridge are covered by the maker’s instructions and by the rules of the place you are in; take them from there.

    Magnum twelve 227 g butane cartridges with an MSF-1a bayonet valve

    • The valve name is in the title, so the fitting is settled before the bullets are read
    • EN 417 is named alongside MSF-1a: a standard and a shape, rather than one or the other
    • Butane alone, with nothing said about how it behaves as the temperature falls

    Best for: Restocking a tabletop stove whose manual names the MSF-1a bayonet fitting, a whole season at once.

    Optimus 100 g EN 417 canister, 50/25/25 butane, isobutane and propane

    Best for: Someone who already knows this cartridge shape from the appliance in their hand and is restocking rather than choosing.
