The ornamental design for a flow-through piping cap, as shown and described.
FIG. 1 is side view of the disassembled flow-through piping cap disclosed herein. The piping cap is disassembled to show the three individual pieces that make up the piping cap;
FIG. 2 is a side view of the assembled flow-through piping cap disclosed herein. Flow-through piping cap is symmetrically cylindrical, therefore a view from any side about its cylindrical axis would result in the same image;
FIG. 3 is a bottom-side view of the flow-through piping cap disclosed herein; and,
FIG. 4 is a top-side view of the flow-through piping cap disclosed herein.
The surface shading is for purposes of illustrating the contour and appearance of the claimed surface upon which is illustrated, but is not actually seen on the surfaces of the flow-through piping cap.
