Self-amalgamating Tape, EB79493150, red, 25 mm × 4.27 m

Self-amalgamating Tape EB79493150 in red, 25 mm × 4.27 m, is a stretchable, yet cohesive insulating tape that fuses to itself to form a seamless, rubber-like layer. When wrapped under tension it creates a tight, conforming seal that provides electrical insulation, water and moisture resistance, and mechanical protection for cables, connectors, and repaired sections. The tape is sized for hand application and intended for both temporary repairs and longer-term protection in indoor and outdoor environments.

Advantages

The tape combines strong elasticity with self-amalgamating properties to produce a continuous, gap-free cover without adhesive residue. Its rubber-like finish maintains flexibility across a range of temperatures and withstands mechanical abrasion and weather exposure. The product is easy to apply by hand, requires no primer or heat to bond, and can be used on irregular surfaces and complex shapes thanks to its conformability.

Suitable for

• Insulating and sealing electrical cable joints and splices
• Emergency repairs of damaged cable insulation
• Moisture sealing for outdoor connections and terminals
• Bundling and mechanical protection of wires and harnesses

Key specifications

• Color: red
• Width: 25 mm
• Length: 4.27 m
• Material type: self-amalgamating elastomeric tape
• Surface finish: cohesive, non-adhesive until stretched and wrapped
• Typical properties: elastic, conformable, weather-resistant

How to use

Clean and dry the surface to be wrapped to remove oils, dirt and loose particles. Stretch the tape while wrapping so that each turn overlaps the previous by at least 50% to ensure full cohesion and a seamless finish. Apply firm tension during wrapping to activate amalgamation; secure the end with additional wraps. For cable joints, start and finish the wrap on sound insulation beyond the damaged area to provide adequate mechanical support. No additional adhesives or heat are required.

Usage recommendations

Store the roll in a cool, dry place away from direct sunlight and ozone-generating equipment. For long-term underground or continuously submerged applications, verify suitability for specific conditions and consider additional protective layers. Wear gloves if prolonged handling is required to maintain hand comfort and cleanliness.
