You may be able to buy pre-made heat shrink tubing but I have a specific label maker for those. All those ends have regular black adhesive lined heat shrink, yellow labeled heat shrink and then a clear heat shrink over it all.
I'm sure there are other brands out there but the brand label maker I use is DYMO.
Wow! I never would've guessed there was three layers of heat shink on each terminal. Thanks for sharing the information.
