Looking at the 1/16" x 1/4" red rubbery extrusion from the non-functional end of a DC motor. It looks like heat shrink tubing over a much shorter extrusion, but it's softer and I don't see any opening on the end of it.

What is it for? Should I be concerned about damaging it or whatever it's protecting?
