OG exemplary drawing
 
1. A fluid end section, comprising:
a housing having a longitudinal axis and opposed first and second surfaces joined by an outer intermediate surface;
a horizontal bore formed within the housing and interconnecting the first and second surfaces, the horizontal bore extending along the longitudinal axis of the housing and configured to receive a fluid routing plug;
a discharge bore formed in the housing and interconnecting the horizontal bore and the intermediate surface;
an intake bore formed in the housing and interconnecting the horizontal bore and the intermediate surface;
a first sealing surface surrounding the horizontal bore and configured to engage a first seal carried by the fluid routing plug, the first sealing surface positioned between the intake bore and the second surface of the housing;
a second sealing surface surrounding the horizontal bore and configured to engage a second seal carried by the fluid routing plug, the second sealing surface positioned between the discharge bore and the intake bore; and
a fluid routing plug engaging surface formed within the housing and surrounding the horizontal bore, the fluid routing plug engaging surface positioned between the intake bore and the second sealing surface;
in which a maximum diameter of the second sealing surface is greater than a maximum diameter of the fluid routing plug engaging surface; and in which the maximum diameter of the fluid routing plug engaging surface is greater than a maximum diameter of the first sealing surface.
