Tesa 51036 High Heat PET Cloth Electrical Tape - Engine Wire Harness

In this review the Tesa 51036 PET cloth tape is evaluated as a practical solution for anyone needing durable wiring protection in high-temperature environments. The bottom line: this kit of 15 rolls is best for mechanics, restoration hobbyists, and DIYers who want a factory-like finish and reliable protection around engine compartments because it resists heat, chemicals, and abrasion while offering strong adhesion that stays put under stress.

Key Features

• High temperature resistance: Rated to withstand -40 C to 150 C (302 F) for extended periods, it protects wiring in hot engine bays without adhesive breakdown.
• Flame retardant construction: The PET cloth substrate and adhesive formulation minimize fire risk and meet the needs of safety-conscious vehicle work.
• Chemical and fluid resistance: The tape resists oils, coolants, and common engine fluids so wrapped harnesses stay protected in harsh environments.
• Enhanced abrasion and tear resistance: The cloth backing and strong adhesive prevent ripping or fraying when routed over edges or through tight spaces.
• 15-roll kit size: Each set includes fifteen 19 mm x 25 m rolls, providing enough tape for multiple projects or full harness jobs.

Who It's For

This tape is aimed at professional technicians and home mechanics who work on cars, trucks, SUVs, and performance engines from manufacturers like Mercedes, BMW, Audi, VW, and Porsche, where heat and exposure demand more than standard electrical tape. It is especially useful when a neat, factory-style finish and long-term resilience are priorities.

Those who should look elsewhere include casual users who only need small amounts of general-purpose tape for indoor low-heat tasks, or anyone requiring electrically conductive or insulating tapes with specific UL electrical ratings not described for this product.

Pros & Cons

Pros

• Strong adhesion delivers a clean, professional finish that customers say mimics factory harness wrapping.
• High heat and chemical resistance keep wiring protected in engine compartments and other demanding environments.
• Cloth construction resists abrasion and tearing for long-term durability around routed harnesses.

Cons

• Because this is a PET cloth tape with specialized adhesive, it is overkill for light indoor electrical tasks and is sized more for vehicle and industrial use.

Specifications

Our Verdict

The Tesa 51036 kit is a dependable choice for anyone wrapping engine wiring or rebuilding harnesses where heat, fluids, and abrasion are concerns. The combination of PET cloth, a robust acrylic adhesive, and a 15-roll supply makes it good value for automotive and marine projects that need longevity and a factory look.
