    Abstract: A pump fluid end includes a body that defines a plunger bore and a working fluid bore that intersects the plunger bore to form a cross bore. A packing bore is defined in the plunger bore and includes a packing sleeve bore, a taper relief bore, and a transition bore. The packing sleeve bore transitions to the taper relief bore at a radial shoulder and the taper relief bore transitions to the plunger bore across the transition bore. The transition bore extends between an external corner contiguous with the plunger bore and an internal corner contiguous with the taper relief bore and at least one of the external and internal corners is rounded and exhibits a radius. The packing bore is treated with a surface pre-stressing treatment.
