Propane has a Vapor Pressure of about 170 at 70*F while Butane Pressure is only 17 PSIG 's

at 200F Propane is at something 650PSIG of pressure while Butane is 47 PSIG's.

Some risks are involved..That little plastic butane tank on the torch is not all that encouraging !

More frighting !

I will be cautious with my butane / propane refilling and Mixing percentages the stock Steel Can's are 30% propane 70% butane mix and are much lighter weight then the Green propane tanks.
