Abstract: This invention relates to an improved attachment for a propane/butane fuel container of the aerosol type to provide torches, burners, heaters, lanterns, and the like. In one embodiment the attachment itself includes a torch and control valve, while in other embodiments it is an adaptor to connect conventional or separate devices to the container. The attachment has a cylindrical boss with a central well which screws onto the threaded stem portion of the fuel container to an assembled position in which an actuator pin opens a self-sealing outlet valve in the container. The attachment has a first O-ring seal seated inside the well and a second O-ring seal seated around the inlet boss just below an outwardly extending shoulder. As the assembly is tightened into position on the fuel container, these two O-ring seals are simultaneously compressed, the first against the upper surface of the stem portion and the second against the annular rim of the container.
