1. A baffle press-fit against an inner portion of an outer tube defining an interior of a hydraulic damper, the baffle comprising:
a first wall;
a second wall, opposite the first wall;
a circumferential third wall having a centerline axis and interconnecting the first wall and the second wall and confronting the inner portion of the outer tube; and
a channel formed between at least a portion of the circumferential third wall and the inner portion of the outer tube, the channel comprising:
an inlet formed along at least a portion of the first wall and the circumferential third wall, and defined by a first cross-sectional area;
an outlet formed along at least a portion of the second wall and the circumferential third wall, and defined by a second cross-sectional area, the outlet being circumferentially offset from the inlet with respect to the centerline axis; and
a groove formed along at least a portion of the circumferential third wall and fluidly coupling the inlet to the outlet, and defined by a third cross-sectional area, wherein the third cross-sectional area is constant between the inlet and the outlet.
