Can I use Jetboil with other fuel canisters?

Jetboil is compatible with valves made to the EN417 specification, a standard adopted by manufacturers throughout the world. Please note that the product has not been tested with every different type of fuel canister, and we cannot claim safe operation with any canister other than our Jetpower brand of fuel.  However, if you are unable to find our fuel out on the trail, the following fuel has the same mixture and valve as ours: Brunton, Gigapower, MSR, Primus and Snowpeak.
