How to Make the Best Motor Insulation Tubes

If ever one needed proof that it’s the simplest, littlest things that often perform the mightiest wonders, motor insulation tubes could provide it!

These tubes generally have an inside diameter of no more than .026″ to 2” and a wall thickness of just .0015″ to .012″. Yet they well insulate the electrical connections in motors, protecting them against mechanical, thermal, and environmental damage.

Motor insulation tubes perform some other useful duties, as well. They can, for instance, serve as shaft spacers and insulators in electric motor armatures, protect battery cables, act as heat shield dielectric barriers, provide lead wire insulation, and be used either as coil forms for starters or alternators, wire splice insulation, or slot insulators and liners.

Little wonders, indeed! And if you were going to make the best motor insulation tubes yourself, you’d want make sure they:

  • had extractable levels below 2% so they’d also work beautifully in hermetic applications such as air conditioners and refrigerators,
  • were tough enough to resist cut-through at splice connections, and
  • could resist vibratory abrasion when used to insulate crossover and lead wires.

The good news is, you don’t have to make your own to get the best motor insulation tubes. PPG has already made them for you. We offer a number of different types, too. Explore our website. Then Contact Precision Products Group if you’d like further details.
