The screw thread and valve arrangement on the MSR Pocket Rocket(tm) conforms to the industry standard, so it can be threaded onto iso-propane/butane canisters from many different manufacturers, such as Sno-Peak and a variety of off-brand canisters. This is not true universally of all propane burners. As I recall, Primus has a proprietary valve arrangement which forces you to use Primus canisters. This is not true of the MSR or Sno-Peak burners and some others.
