Fluid routing plug

A fluid end, comprising:

• a housing having a bore formed therein, the bore comprising a counterbore;
• a fluid routing plug, at least partially disposed within the bore, the fluid end comprising
• a body extending along a longitudinal axis having:
• a first end surface;
• a second end surface;
• and
• a radially disposed outer surface, extending between the first end surface and the second end surface;
• the outer surface including:
• a first surface section positioned proximate the first end surface, the first surface section configured to receive a first annular seal;
• a second surface section proximate the second end surface, the second surface section configured to receive a second annular seal;
• and
• an intermediate surface section disposed between the first surface section and the second surface section;
• wherein the body defines:
• a first plurality of fluid passages, the first plurality of fluid passages extending from the intermediate surface section to the second end surface;
• and
• a second plurality of fluid passages, the second plurality of fluid passages extending from the second end surface to the first end surface;
• wherein each of the second plurality of fluid passages is non-parallel to the longitudinal axis;
• and
• a hardened insert installed within the bore and surrounding at least a portion of the fluid routing plug, the hardened insert engaging a base of the counterbore and engaging the outer surface of the body;
• in which the hardened insert engages one of the first annular seal and the second annular seal.
