51036 High-Performance PET Cloth Automotive Wire Harness Tape, Black, 19mm x 25m, 1 Roll

This Tesa tape is exactly what I needed for wiring harness work. It sticks securely, doesn’t peel back with heat, and has that professional OEM look you see in factory looms. Easy to tear by hand, wraps tight, and resists fraying. Much better than standard electrical tape — this will be my go-to for car projects from now on.

Perfect excellent for electrical wires

It seemed like the same wiring harness tape on my Audi. Perfect

well its made of clothi used it to cover exposed copper wiring on my EVSE juicebox charging cableits already showing the bare copper again after moving the cable to/from the vehicle charginga few months nowthis is more for engine compartment, under dash wiring, etc.where it will not be exposed to abrasion or movement

Great under hood repair wrap tape for electrical and small cables.

Apparently this tape is well-known in automotive restoration circles and less known to most of us shade tree mechanics. If you're messing around with automotive electrical, this stuff is a must have! I also highly recommend the expandable braided sleeving.This doesn't leave sticky residue on wires like you might experience using plain old electrical tape. It's plenty sticky for wrapping wiring harnesses to provide additional insulation and protection.I would recommend buying a few rolls of this stuff because you WILL go through it fairly quickly, all depending on the length and diameter of the bundle that you're wrapping. This is something that you'll want to keep in your toolbox now that you know about it.

UPDATE: Had a small engine bay fire that took me 20-30 seconds to fully put out. On the wiring that i had wrapped in 51036, the wiring inside of the tape was in perfect shape. The tape "melted" and turned into like a hard plastic case around the wires, and saved the wiring! The wires that were wrapped in the factory tape or that were just bare were destroyed.This 51036 is noticeably stiffer than the 51608 interior tape Tesa offers. Also seems a lot more durable and abrasion resistant, definitely need a razor or sharp knife to cut it, it's not as easily tearable like 51608.Goes on easily, not as stretchy as 51608. Sticks to itself very well. It should be pretty heat resistant and fire retardant. Doesn't seem to leave any residue like regular electrical tape. Looks much cleaner than electrical tape wrapping, sticks better, doesn't leave residue, and is overall a better solution

Great stuff, used on my electrical harness for my truck's engine.
