A pair of spaced tubular half-shells (16,18,32,34) are stamped in each of two separate sheets (12,14) of metal which are then joined at their margins (44) to form two mixer tubes each having an inlet end with a venturi for connection to a fuel gas supply and an outlet (42) end adapted for connection to a burner. The space between the mixer tubes is stamped to form a pair of grooves (52,54) which lock and seal the sheets together to prevent the fuel/air mixture from leaking from one mixer tube to the other. |
