An apparatus for providing, in a continuous or intermittent manner, a superheated vapor of an organic liquid, such as methylene chloride, for reflowing plastic surfaces or causing a plastic material to flow onto a surface to create a film or coating thereon. The apparatus includes a tubular metal member defining a flow passage for both the liquid and gaseous phases of the liquid being vaporized. A vapor flow control member having a vapor flow orifice is provided at one end of the tubular member while the other end of the tubular member communicates with a source of organic liquid under pressure through an on-off valve. A source of electrical energy is connected in circuit with the tubular member through a switch operated concurrently with the valve whereby electrical current is caused to flow through the tubular member to heat the member to a temperature adequate to vaporize the liquid flowing therethrough. The tubular member is electrically and thermally insulated by a shield and a handle associated with the shield contains the valve and switch.
