A method of making a polymeric sleeve comprising:

• placing a lower mold component, the lower mold component structurally defines a negative image of an insertion end of the polymeric sleeve, and the lower mold component defines a negative image of a first portion of a main passageway of the polymeric sleeve;
• assembling into mating relationship a disk assembly, the disk assembly structurally defines a negative image of an internal volume of the polymeric sleeve, and the disk assembly defines a negative image of at least two stanchions and a first flange;
• stacking the disk assembly into mating relationship with the lower mold component;
• coupling a rod member to the disk assembly, an exterior surface of the rod member defines a negative image of the main passageway from the internal volume to a vent end of the polymeric sleeve;
• closing an outer mold assembly around the disk assembly and rod member, an interior surface of the outer mold assembly structurally defines a negative image of an outer surface of the polymeric sleeve;
• and
• injecting a polymeric compound in a liquid state into the outer mold assembly.

A mold system for creating a polymeric sleeve, the mold system comprising:

• a lower mold defining a mold surface and a stem that protrudes upward from the mold surface along a longitudinal axis;
• a disk assembly configured to stack into mating relationship with an upper end of the stem, the disk assembly defining at least two channels into a first interior volume that circumscribes the longitudinal axis;
• and
• a rod configured to couple to an upper surface of the disk assembly and extend along the longitudinal axis.
