Insulation tape Tesa Isolierband flex 4163 — white, 33 m x 19 mm

Tesa Isolierband flex 4163 — white, 33 m x 19 mm is a flexible electrical insulation tape designed for insulating, bundling and repairing wiring in residential and light commercial applications. The tape combines conformability with reliable adhesive performance to create a secure, neat finish on joints and cable sheaths. Its white color provides a clean appearance and simple color-coding for installations.

Advantages

The tape offers flexible handling that follows irregular shapes and tight radii while maintaining consistent adhesion. It provides good electrical insulation properties and a tidy visual result when applied to joints or wrapped around conductors. The product is easy to unwind and cut to length, enabling precise application during maintenance and repair tasks.

Suitable for

• Insulation of electrical splices and joints
• Bundling and securing wire harnesses
• Repairing minor damage to cable sheaths
• Color-coding and marking in installations
• General household and light commercial electrical maintenance

Key specifications

• Color: white
• Length: 33 m
• Width: 19 mm
• Material type: flexible PVC-based electrical insulation tape
• Adhesion: pressure-sensitive adhesive suitable for electrical applications
• Properties: conformable, tearable by hand for quick application

How to use

Clean and dry the surface of wires or cable sheaths before applying the tape. Start wrapping with a half-overlap on the first turn to ensure complete coverage, and continue with even tension until the damaged area or splice is fully covered. For bundling, wrap several turns to achieve the desired thickness and secure finish. Tear the tape by hand or cut with scissors at the end of the application, pressing the final layer to ensure adhesion.

Recommendations

Use this tape for indoor electrical work and light-duty outdoor tasks where exposure to direct sunlight, extreme temperatures or prolonged moisture is limited. For high-voltage applications, professional-grade materials and local regulations should be consulted. Store the tape in a cool, dry place away from direct sunlight to preserve adhesive properties.
