Abstract: An apparatus for wellbore fluid treatment having a body with a lower end, an upper end, an exterior surface and an interior surface defining a long bore open at the upper end, an outlet port spaced from the upper end, and a die in the long bore between the upper end and the outlet port. The outlet port permits the communication of fluids between the long bore and the exterior surface. The die is substantially immovable within the long bore and has an inner open diameter in which a plug is landable to create a seal in the long bore before passing through the inner open diameter.
