A side-pocket gas lift mandrel having tapered end caps threaded onto the ends of the mandrel with metal-to-metal sealing threads. The thickness of each made up thread set is the same as the thickness of the small end of each end cap, resulting in a mandrel having the same outside diameter as if the end caps were welded on, without sacrificing any inside diameter in the small ends of the end caps, compared to a welded mandrel.
