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.

Subject: What is this red rubbery DC motor part?

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

Thank you.
