A protector for an electric submersible pump system has a pressure resistant housing and a mandrel sealingly engaged with an interior of the housing to define a fluid tight chamber in an annular space between the housing and the mandrel. The mandrel has a fluid port at one longitudinal end. A labyrinth tube is in sealed fluid communication with the fluid port, and is wound around the mandrel to longitudinally traverse the mandrel toward another longitudinal end thereof and back toward the fluid port. An end of the labyrinth tube is fluidly exposed in the fluid tight chamber.
