Abstract: A downhole tool is described can be used for handling waste fluids separated from desired hydrocarbon production fluids. The waste fluids are injected into a disposal formation. The tool is produced to avoid blockage of fluid flow passages and to reduce or eliminate the creation of a pressure differential across the tool. The tool is adaptable to be used with various sizes of pumps, to accommodate various pump intake filters and to conform to API tolerances. The downhole tool includes: an inner tube having a longitudinal bore, a seal disposed at the lower end of the longitudinal bore, an outer tube having an outer surface and being disposed about and spaced from the inner tube. An annulus is formed between the inner tube and the outer tube and is open at each end. A threaded connection is formed at the upper end of the outer tube to connect the outer tube to a tubing string such that the annulus opens into the tubing string's longitudinal bore.
