1. A fluid end kit, comprising:
a housing having an external surface, an internal chamber, and at least two conduits independently interconnecting the external surface and the internal chamber, each conduit comprising a longitudinal axis;
a first plug configured to be closely received within a selected one of the conduits and configured to block the flow of fluid within such conduit, the first plug comprising:
a body, comprising:
an axis that is configured to be colinear with the longitudinal axis; and
one and only one circumferential recess formed therein; and
a second plug configured to be closely received within the same selected one of the conduits as the first plug and configured to block the flow of fluid within such conduit, the second plug comprising:
a body, comprising:
an axis that is configured to be colinear with the longitudinal axis; and
one and only one circumferential recess formed therein;
in which the respective recesses would be axially offset if the first and second plugs were superimposed.
