<p>PURPOSE:To provide a tube fitting, which can be formed and connected easily, by integrally connecting both ends of an intermediate member to the respective opposite ends or a pair of connecting members, which have been provided with an electric heating wire arranged at an internal periphery of the end, into which a tube is to be inserted, and a connector pin arranged at an external periphery. CONSTITUTION:A pair of connecting parts 10 and 11 have respective sleeves 15 and 16 having male threads at the respective central sides and internal diameters into which respective plastic tubes to be connected to the connecting parts 10 and 11 can be inserted. In addition, respective electric heating wires 12 are buried in the internal periphery. Furthermore, respective connector pins 13 and 14 are buried at both ends of the respective connecting members 10 and 11 so as to project outwards respectively, and both ends of the electric heating wires 12 are connected to the connector pins 13 and 14. Furthermore, respective female threads 61 and 62 formed on both ends of an intermediate member 60 are engaged with the respective male threads of the respective connecting members 10 and 11 through packings 63. In order to connect tubes by this tube fitting, the respective tubes are fusion-bonded with this tube fitting by supplying current to the electric heating wires 12 after inserting the tubes into the respective opposite sides of the respective connecting members 10 and 11.</p> |
