3 Tesa 51036 PET Cloth High Heat Electrical Tape for Wire Harness, Cables for Automotive Engine, Protect Against High Temperature, Abrasion, Chemical & Fluid | Flame Retardant | Black

As an engineer with over 15 years of experience in the wire harness manufacturing industry, I can confidently say that the Tesa 51036 PET Cloth High Heat Electrical Tape meets true OEM standards.This is not your typical electrical tape. It’s the same style of PET cloth tape widely used in automotive production for harness wrapping. The material and adhesive combination provide excellent heat resistance and long-term durability, especially in demanding environments like engine bays.What stands out from a professional standpoint:High abrasion resistance – ideal for protecting harnesses against vibration and frictionStable, strong adhesion – does not become gummy or degrade over timeExcellent flagging resistance – stays in place once appliedProfessional OEM finish – delivers that clean, factory-style harness lookFlexibility with strength – easy to apply while maintaining durabilityIn my hands-on experience, this tape performs significantly better than standard vinyl electrical tape, particularly in high-temperature and high-vibration conditions. It’s clearly designed for long-term reliability and consistent performance.Cons:Higher cost compared to basic electrical tapeRequires scissors or a blade to cutConclusion:If you’re working on automotive wiring—whether professionally or as a serious DIYer—this tape is absolutely worth it. It provides a reliable, OEM-quality solution for proper harness protection and finishing.

Great product that is very durable and easy to use. I have used them on engine wiring for heat resistance.

Top notch. Used daily in hand making complex Fiat industrial engine wiring harnesses. Wire grouping wrapped every 14 inches to bundle wires. Harnesses are clamped to engine body. Wiring is covered with split sleeving and tape wrapped around sleeve to hold fast and closed. Heat does not cause to unravel, very tough and durable.

Im a master mechanic and this is the best electrical tape I have ever used.

I need to repair and replace the 20 year old wiring harness material on my older Toyota Sequoia. This tape was easy to apply, great texture and stickiness, and appears to be very durable. I wanted the proper high heat tape that could be used around the engine, without melting or worse (catching fire). This tape is key for safely replacing the old wire harness cover and to prevent oil leakage from soaking the wires. Great product for this task.

I rate this a 4 because I have not used it yet. Appears to be exactly what I was wanting for a project that is upcoming.Great delivery time. Thanks

Stuff is awesome, looks like it belongs there , isn’t all gummy like electrical tape.

I've used a lot of Tesa 51608 tape and got some of this 51036 for where I wanted more abrasion resistance.For those wondering what the difference is between this 51036 and the 51608,51036 is stickier, tougher, not "fluffy", and can't be torn by hand.51036 has pretty much zero stretch.51608 is handier to use since you don't need a sharp knife or scissors to cut.51608 also has a little stretch making it easier to neatly bundle cables.51608 has less stick than the 51036. It sticks well to itself but not so well to other materials. Probably ideal for a cable loom tape.Both are great tapes, but each has their place.Also - a warning - watch out for some vendors selling similar description (not Tesa) tape at a reduced price. I tried some of it and it was pure junk. Wouldn't stick to anything.BTW, this vendor - Prime Ave - is good to deal with. Answered questions I had promptly.

This tape is very high quality and will clean up and old looming.
