Heat shrinkable Dual wall tubes are designed to provide environmental sealing in automotive splices. Hot melt adhesive prevents entry of moisture between the wires.
Applcation
- The tubing is inserted over the splice area and on heating the tube starts shrinking and the adhesive melts and squeezed around where the wires are crimped or welded connectors.
- Light duty wire harnessing for electrical and electronic applications.
- Provides electrical insulation and protection for in-line components.
- Used as strain relief for electrical wire connection.
- Good flexibility and provides mechanical protection.
- Flame retardant tubes lowers the risk of electrical fires.
