The ornamental design for a tool to crimp non-metallic tubing onto fittings, as shown and described.
FIG. 1 is a front left perspective view of my tool to crimp non-metallic tubing onto fittings showing the design when the tool is open, the front right view being a mirror image;
FIG. 2 is a front right perspective view of the tool of FIG. 1 showing the design when the tool is in operation; and,
FIG. 3 is a slightly different angle of the perspective view shown in FIG. 1 with the jaws of the tool in the closed position.
Evenly-spaced broken lines showing the back hinge end of the tool, pliers, and plumbing components are included for the purpose of illustrating the unclaimed environmental structure of the tool to crimp non-metallic tubing onto fittings and form no part of the claimed design. The unevenly-spaced broken lines which define the bounds of the claimed design form no part thereof.
Both the top and the bottom are devoid of surface ornamentation. Characteristic features of the invention include a pleasant tapering of the jaws opposite the hinged end of the tool.
