The detail adaptor can also be used on its own as a straight jet nozzle tool or along with the 90 degree jet nozzle attachment. These tools are great for cracks and crevices. Make sure to concentrate the steam directly on the area to be treated with as minimal distance as possible, no more than 1” away. The steam will condense and cool off and not be effective to kill pests and their eggs if the jet tip is not directly on the surface being treated. The detail adaptor can be attached directly to the steam gun or to any of the extension tubes.
