Heat-shrink Double Insulation Roll Tesa 05418-00001-02 2.5 cm x 0.095 cm Ø 2.2 cm Black

Tesa Double Insulation Roll is a heat-shrink insulation product in black designed to provide an additional protective layer for electrical wiring, connectors and splices. The roll delivers a compact insulating sleeve after shrinkage, helping to reduce the risk of short circuits and mechanical wear. Its flat roll format allows cutting to required lengths for repair, retrofitting or new installations where a double insulation barrier is required.

Advantages

This heat-shrink double insulation roll features a consistent wall thickness and an inner diameter that enables easy application over wires and small connector assemblies. The material shrinks uniformly when heated to form a tight, protective layer that resists abrasion and improves insulation performance. Supplied in a roll format, it is convenient for on-site cutting to length and reduces waste compared with pre-cut sleeves.

Suitable for

• Electrical wire insulation and repair
• Sealing and insulating crimped connections and soldered joints
• Adding a secondary insulation layer to cables and harnesses
• General maintenance and retrofit work in household and light industrial settings

Key specifications

• Color: black
• Width: 2.5 cm
• Wall thickness (before shrink): 0.095 cm
• Inner diameter (before shrink): 2.2 cm
• Form: roll for cutting to length
• Function: heat-shrink double insulation for electrical protection

How to use

Cut an appropriate length from the roll to cover the exposed section of wire or connector plus a small overlap on each side. Slide the material over the component to be insulated, ensuring full coverage of the connection or splice. Apply heat evenly with a heat gun, hot-air tool or suitable alternative until the material shrinks uniformly and conforms tightly around the substrate. Allow the sleeve to cool before handling to ensure a stable insulating layer.

Recommendations

Use appropriate heat tools and observe manufacturer safety guidance for heat-shrinkable materials. Avoid open flames and excessive heat that could damage underlying components. For critical electrical applications, verify compatibility with operating temperatures and insulation requirements before installation.
