ABSTRACT:
An electroconductive composite tube assembly is provided. The assembly includes a metal end member having at least one cylindrical wall. A tube main body of PTFE and having an outer circumferential surface is further provided. The outer circumferential surface of the tube main body is disposed in engagement with an inner circumferential surface of the cylindrical wall of the metal end member. An electroconductive tube formed from a heat-shrinkable resin is disposed over the cylindrical wall of the metal end member and over the outer circumferential surface of the tube main body. The electroconductive tube is heat-shrunk into laminated engagement with both the cylindrical wall of the metal end member and with the outer circumferential surface of the tube main body to enable efficient grounding of the electrostatic charges developed in the composite tube.
