Tesa 51036 High Heat PET Cloth Electrical Tape - Durable Engine

In this review the focus is on the Tesa 51036 PET cloth electrical tape and why it is a practical choice for vehicle wiring projects. It is aimed at mechanics, DIY home garage users, and workshop technicians who need a reliable harness wrap that resists heat, chemicals, and abrasion; the single biggest reason to buy is its proven temperature range and flame retardant construction which preserves wiring in harsh engine compartments.

Key Features

• High temperature resistance: Rated to withstand from -40 C to 150 C (302 F) over prolonged exposure, it protects wiring in hot engine bays without adhesive failure.
• Flame retardant PET cloth: The PET cloth construction combined with a flame retardant formula reduces risk of spread and improves safety around heat sources.
• Advanced acrylic adhesive: The solvent-free, triple A adhesive provides strong initial tack and long-term adhesion on cables and harnesses.
• Chemical and fluid resistance: Tested for resistance to common automotive chemicals and fluids so wrapping stays intact near fuel, oil, and coolant lines.
• Abrasion and tear resistance: Reinforced cloth resists ripping and wear from vibration and movement in the engine compartment.
• Bulk kit for projects: Includes eight 19mm x 25m rolls so there is enough tape for multiple harnesses or larger installations.

Who It's For

The Tesa 51036 is best suited to automotive technicians, restoration hobbyists, and anyone working on European cars such as Mercedes, BMW, Audi, VW, and Porsche where durable, factory-style harness wrapping is desired. It also fits marine, RV, and powersport applications where higher heat and fluid exposure are common.

Users who only need general-purpose household electrical tape for low-voltage indoor tasks should look elsewhere; this product is optimized for high-heat, high-abrasion environments rather than basic home wiring or temporary fixes.

Pros & Cons

Pros

• Professional-looking finish that mimics factory harness wrapping and improves cable organization.
• Durable adhesive and cloth construction provide long-term resistance to heat, chemicals, and abrasion.
• Bulk pack of eight rolls offers strong value for workshops and multi-vehicle projects.
• Works across many vehicle types and propulsion platforms for versatile use.

Cons

• Not intended as a substitute for heat-shrink at sealed connector points, so additional materials may be required for fully sealed joints.
• Relatively specialized; overkill for simple indoor low-heat electrical tasks.

Specifications

Our Verdict

The Tesa 51036 PET cloth harness tape is a sensible buy for anyone needing a rugged, heat-resistant wrap that resembles factory installation and holds up to chemicals and abrasion. For automotive and marine wiring projects it offers good value in an eight-roll kit and delivers a clean, long-lasting finish; choose it when durability and professional appearance matter.

Frequently Asked Questions

Can this tape handle continuous engine heat?
Yes. It is rated for sustained exposure up to 150 C (302 F) and is designed specifically for engine compartments.

Is the adhesive solvent-based?
No. The tape uses a solvent-free advanced acrylic adhesive often described as triple A for strong tack without solvent residues.

Will it replace heat-shrink on connectors?
No. It protects and tidies harnesses well, but heat-shrink is recommended for sealed, strain-relieved joints and individual connector insulation.
