Wire harnessing tapes helps manufacturers to form, route and protect cables to facilitate production of electrical distribution systems and vehicle assembly as well as ensuring functionality in all conditions reducing the risk of short circuits or malfunctions.
Nowadays, cars are not only examples of high-quality mechanical engineering but also true high-performance computers. Thanks to their complex sensor and control systems, vehicles may need up to 8 km of cable and wires for data and power transmission. This is why we offer wire harness tapes and sleeves covering all vital automotive applications – from providing protection against noise and abrasion to resisting temperature and environmental conditions.
The automotive sector is always innovating. So, our experts work closely with wire harness manufacturers and OEMs to ensure they meet the demands of the major players. For example, we’re developing 2D and 3D shaping solutions using our wire harness tapes to optimize space, minimize routing, and save up to 80% weight compared to non-tape solutions.
Manufacturers worldwide rely on tesa® wire harness tapes thanks to their exceptional durability and reliability. Easy to tear by hand, with excellent cable compatibility and a stable unwinding force, our tapes can be easily integrated into manual and automatic assembly line processes. They are a cost-effective, flexible solutions for protecting vital electrics from abrasion, noise, heat, and age. As part of a sustainable supply chain, we are committed to an eco-friendlier production.
Here at tesa, we offer an extensive assortment of wire harnessing tapes. We work closely with manufacturers across the world to develop the right solutions for the automotive industry. That’s why our high-performance tapes feature a choice of adhesive formulations, backing technologies, and coating processes. And of course, all our tapes meet relevant industry standards and norms.
Our product assortment is designed to meet your needs. So, whether you are looking for reliable bundling or flexible sleeves, noise dampening, or added protection from abrasion or heat damage, there is a tesa tape that offers the flexibility, durability, and reliability you demand.
Compared to other traditional solutions, wire bundling tapes offer significant efficiency and cost advantages. In addition to general bundling applications, our tapes are ideal for spiral wrapping and covering splices too. Many of our wire bundling tapes are optimized for smooth and efficient manual applications – soft, flexible, and easy to tear by hand. All feature a stable unwinding force and are flame, age, and flagging resistant.
Our versatile sleeves are increasingly popular in manufacturing, where wire bundles are becoming progressively thicker and stiffer and routing space is at a premium. By minimizing or in some cases even eliminating adhesive contact to the wires, our solutions provide high harness flexibility while still guaranteeing a secure bond. The tesa® sleeve assortment can be easily and efficiently applied lengthwise. With additional noise dampening and abrasion resistance, they are the logical choice for anyone looking for lightweight, flexible, and space saving cable management.
Car passengers expect a quiet, smooth ride. Any sound in the cabin can quickly become annoying or even concerning. It’s therefore paramount that manufacturers ensure noises are reduced to a minimum. Noise dampening tapes from tesa are available with PET fleece or PA velour backings to deliver basic to high sound dampening performance. They can withstand numerous challenges such as mechanical and chemical stress as well as extreme temperature variations.
tesa’s abrasion protection tapes are engineered to deliver long-lasting performance in demanding automotive environments. Featuring solvent-free acrylic adhesive and durable PET or PA cloth backings, these tapes ensure exceptional cable compatibility across all standard wire harness applications.
Designed for extended durability, especially in high-stress areas such as engine compartments, tesa tapes provide reliable protection against mechanical wear. Their abrasion-resistant properties help maintain the integrity of wiring systems over time, offering manufacturers a trusted solution for long-term wire harness protection.
Harness parts installed in close proximity to heat sources such as engines, motors, or turbocharges can often be exposed to radiant heat. To combat the threat of heat damage to vital electrical wiring, the tesa selection of heat protection tapes use durable, long-lasting aluminum coated glass cloth backing. The shiny aluminum surfaces reflect heat and ensure maximum thermal effectiveness under very high temperatures up to 200 °C (392 °F). The selection of tesa® heat protection tapes also includes products featuring acrylic adhesives that are compatible with new halogen-free cable jacketing materials (PE/PP). For enhanced protection against high heat exposure, tapes featuring a silicone rubber laminated glass fiber cloth backing or a self-fusing silicone backing provide superior mechanical durability, excellent electrical insulation, and long-term reliability.

As the development of new e-powertrains and additional features for electric vehicles progresses, automotive wire harnessing will continue to grow in complexity. This is mainly due to factors such as the integration of multi-voltage levels, along with further modularization and miniaturization of components.
To address these challenges, we offer innovative solutions for 48V and high-voltage systems. Our colored cloth and fleece marker tapes increase safety and provide visual differentiation for specific harnesses within the vehicle, for example, by highlighting “no-cut zones.” Additionally, our crash protection tapes safeguard critical components from damage and potentially severe impacts to passengers. Our EV wiring tapes are specifically designed to ensure the comfort, safety, and reliability of electric vehicles.
With the automotive transformation to electric vehicles, safety is a rising concern in automotive design. At tesa, we address this challenge with high-performance wire harnessing tapes targeting the most critical risk areas: fire protection, abrasion resistance, and crash safety. Our solutions, e.g., tesa® 67003, 69000, and 63000, are engineered to protect cables under extreme conditions, helping manufacturers enhance vehicle safety and meet evolving industry standards.
Vehicles are becoming more advanced, and so are their electrical systems. Automation is essential to managing this growing complexity while maintaining agile and efficient production. Our tapes are designed to support high efficiency workflows by enabling precise and repeatable results in automated assembly. Whether you use standard machines or advanced robotics, our tapes help speed up wire wrapping, ensure consistent quality, and optimize resource use. This empowers OEMs and wire harness manufacturers to accelerate production and keep pace with increasing design challenges
Here at tesa, we recognize the importance of sustainability, not only for us, but for our customers too. We are constantly developing more eco-friendly adhesive solutions and products. We have identified five action areas for our business
As part of our mission, we aim to provide cutting-edge solutions for eco-friendly wire harnessing that support environmental responsibility without compromising on quality. For example, our tesa® 61623 rPET non-woven wire harness tape (opens in a new window or tab) features a solvent-free, rubber-based adhesive and backing with 80% PCR PET content.
