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 friction Stable, strong adhesion – does not become gummy or degrade over time Excellent flagging resistance – stays in place once applied Professional OEM finish – delivers that clean, factory-style harness look Flexibility with strength – easy to apply while maintaining durability In 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 tape Requires scissors or a blade to cut Conclusion: 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.

Good stuff here for doing wire harness in automotive or other applications. I would recommend getting appropriate size shrink tubing to cinch the end so it doesn't come unraveled over time. It gives a nice oem look to your projects.

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.

Tessa tape works great

Tape quality is as expected, condition of the tape on arrival is another story. Not sure what’s going on here

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

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

TAPE NEGRO SUPER PARA CABLES ELECTRICOS.

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