4:1 Waterproof Dual Wall Heat Shrink Tubing With Glue


E-FLEX® Dual Wall Heat Shrink is a dual-wall, adhesive-lined polyolefin heat shrink tubing. It features a high 4:1 shrink ratio, making it ideal for environmental sealing and protection of components with large diameter differences. The tubing consists of a polyolefin outer layer and an inner hot-melt adhesive that bonds effectively to plastics, steel, and polyethylene. It provides superior protection against water, moisture, and contaminants, with a continuous operating temperature range of -45°C to 125°C.



What's Special about Glue Lined Heat Shrink Tubing?

  • Wide Operating Range: Designed for reliable performance in extreme high and low-temperature environments.  
  • High Shrink Recovery: Requires high heat for a complete and tight seal around components.  
  • Excellent Mechanical Strength: Offers high tensile strength and superior flexibility to withstand physical stress.  
  • Reliable Insulation: Provides high-performance electrical insulation and high volume resistivity for safety.  
  • Flame Retardant: Self-extinguishing properties that meet standard safety requirements.
