We claim the ornamental design for a U-bend fitting, as shown and described.

FIG. 1 is a perspective view of a U-bend fitting embodying the ornamental design of the present invention;

FIG. 2 is a front view of the U-bend fitting;

FIG. 3 is a rear view of the U-bend fitting;

FIG. 4 is a side view of the U-bend fitting, the opposite side view being a mirror image;

FIG. 5 is a top view of the U-bend fitting; and,

FIG. 6 is a bottom view of the U-bend fitting.

The broken lines in FIGS. 1-6 are for illustrative purposes only and form no part of the claimed design. More specifically, dashed broken lines indicate unclaimed features. Dot-dash broken lines, shown with heavier weight than the dashed broken lines, define boundaries of the claimed design and may also correspond to unclaimed features, but do not correspond to claimed features.
