EN 417

EN 417 is a European Standard concerning non-refillable metallic cartridges for liquefied petroleum gases.

This informal use is improper, as the EN 417 standard applies also to cartridges that do not have a Lindal valve, such as the valveless, pierceable Epigas canisters often used in Europe.

Unlike a pierceable, disposable canister, a Lindal valve should seal itself if the fuel container is unscrewed from the equipment to which it is attached.

A dirty valve can leak, and the thread can be damaged by external force.

Among suppliers of gas cylinders and camp stoves are Epigas (Coleman), Sievert, GoSystem, Primus, Brunton, Jetboil, Mountain Safety Research, Snow Peak, Trangia, Rothenberger, and Campingaz.
