The Coleman C300 Performance cartridge contains 240 g of butane/propane gas mix, which burns steadily across a wide range of temperatures at lower altitudes, making it a good everyday fuel for backpacking stoves, lanterns and small burners. It has a standard EN417 screw-on connection and Coleman's double-safety resealable valve, so it can be removed from an appliance and refitted later without leaking. It suits Coleman screw-thread gas appliances such as the FyreLite and FyreStorm stoves and other EN417 appliances. The cartridge is about 105 x 90 mm. Store in a cool, ventilated place away from flames. Never pierce or burn the cartridge, even when empty.
