Accessory fitting used with equipment for filling surface cracks

A material handling fitting consisting of a tube having inlet and outlet ends, with the tube being stepped between its ends and having a plurality of respectively opposed outer and inner land areas of progressively smaller to larger diameters from one of its ends to the other. The different respective outer and inner land areas are sized to correspond to and telescopically cooperate selectively with inner and outer land areas respectively of substantially conventional material dispensing members, over a wide range of sizes and types. Upon two of such members being telescoped simultaneously with the opposite fitting ends, separable leakproof joints can be established for defining a continuous passageway between the dispensing members via the fitting, suited for conveying therethrough material under pressure.
