An apparatus and method for uniformly dispensing a fluid, such as a lubricant, in the interior of a conduit for easing the installation of wires or other conductors within the conduit employ a series of tubing sections filled with the fluid and a corresponding series of interconnected elongated rods. The tubing sections are attached by clamping loops to the interconnected rods so that a portion of the tube wall in each section is clamped closed. One end of the section includes a slit or other opening through which the fluid within the tubing section can be dispensed. The sections of tubing are inserted into a conduit by means of the interconnected rods, and the fluid is dispensed from the tubing sections into the conduit interior by pulling the tubing sections relative to the clamping loops in the rods and thereby progressively and continuously moving the clamped tube wall portion along each section toward the opening at the one end of the section to expel the fluid.
