Duct Tape Hellermann Tyton 711-00400

HellermannTyton 711-00400 is a silicone self-amalgamating tape designed for outdoor and high-temperature electrical applications. The tape resists weathering, UV exposure and oil, and fuses into a solid mass after application. It is suitable for insulating high-temperature silicone‑insulated cables, protecting outdoor machinery and transformer connections, and for general sealing and repair tasks. Dimensions: 9.1 m length, 25 mm width, 0.51 mm thickness; temperature resistance up to 180 °C and elongation at break of 400%.

Advantages

The tape is chemically cross-linked silicone rubber that self-amalgamates and self-cleans, creating a continuous, water‑tight and erosion‑resistant layer. Its triangular cross-section with a centre line enables precise half‑overlap application and reliable creepage resistance. The material fuses into a solid mass after wrapping, improving mechanical stability and long-term performance in outdoor or oily environments.

Suitable for

• Insulating high-temperature silicone‑insulated cables
• Sealing and protecting outdoor machinery and transformer connections
• Bundling, marking and repairing cable harnesses and wiring
• Temporary or permanent sealing where weather and UV resistance are required

How to use

Clean and dry the surface before application. Start wrapping from the end of the repair or cable, stretching the tape slightly to activate self‑amalgamation and overlap by approximately half using the centre line as a guide. Continue wrapping until the target area is fully covered, then press the final turn to ensure fusion into a continuous mass. Allow time for the material to fuse and stabilize before subjecting the repair to mechanical load or full environmental exposure.

Usage recommendations

Use this tape on compatible silicone‑insulated cables and metallic or polymer surfaces free of heavy contaminants. For electrical insulation on live circuits, follow local safety regulations and apply only when allowed by procedures. Store in a cool, dry place away from direct sunlight to preserve material properties.
