ABSTRACT OF THE DISCLOSURE A method and apparatus for dispensing a fluid in a conduit and more particularly for dispensing lubricant within an electrical conduit for facilitating pulling electrical cables through the conduit. The apparatus is in the form of a cartridge disposed in the conduit at an end thereof. The cartridge is made of a pair of sealed and separable members. One of the members is a flanged sleeve forming the casing of the cartridge, in which is coaxially disposed the separable member forming a tubular support member or carrier for a mass of resilient and absorbent lubricant impregnated porous material compressibly packed between the inner surface of the sleeve casing and the carrier. A cable pulling strand, or fishtape, is passed through the tubular carrier, and the cables to be pulled through the conduit are attached to the end of the fishtape. A plug inserted in the open end of the tubular carrier prevents the fishtape and the cables attached thereto from being pulled back through the carrier. The carrier separates from the sleeve casing when a pull is exerted on the other end of the fishtape. The mass of resilient and absorbent material supported by the carrier expands to the inner diameter of the conduit when leaving the sleeve casing and absorbs part of an additional supply of lubricant contained in the cartridge. Pulling the lubricant-impregnated mass of resilient and absorbent material on the carrier ahead of the electrical cables coats the wall of the conduit with a film of lubricant.
