9. A packing sleeve for a pump fluid end comprising:
a body with a first end, a second end, a bore, an exterior surface, an interior surface, and a center axis;
wherein the exterior surface comprises:
a first exterior tapered surface adjacent to and axially between the first end and a second exterior tapered surface, wherein the first exterior tapered surface has a first angle;
the second exterior tapered surface adjacent to and axially between the first exterior tapered surface and a first exterior cylindrical surface, wherein the second exterior tapered surface has a second angle;
the first exterior cylindrical surface extending axially along the center axis with a first diameter and adjacent to and axially between the second exterior tapered surface and the second end; and
a first exterior cylindrical groove with a first groove depth and a first groove width proximate the first end and axially within the second exterior tapered surface;
wherein the interior surface comprises:
a first inner cylindrical surface extending axially along the center axis with a first inner diameter and is adjacent to and axially between the first end and a first inner transition surface;
the first inner transition surface adjacent to and axially between the first inner cylindrical surface and a second inner cylindrical surface;
the second inner cylindrical surface extending axially along the center axis with a second diameter and adjacent to and axially between the first inner transition surface and a second inner transition surface;
the second inner transition surface extending axially along the center axis and adjacent to and between the second inner cylindrical surface and a third inner cylindrical surface; and
the third inner cylindrical surface extending axially along the center axis with a third diameter and adjacent to and axially between the second inner transition surface and the second end.
