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.
