Looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief?

ELECFUN heat shrink tubing is a great solution, which used in automotive, marine electronics, DIY, and home wiring projects. Such as: 1.Electrical insulation (wire repairs, insulating terminals wires, protecting charging cables, car battery cable ends) 2. Environmental seal to protect from moisture, UV, fuel, and chemicals 3. Strain relief for electrical terminals 4. Grouping loose wires (usually in wire end) 5. Creating thermal insulation for heat-sensitive components 6. Protecting surfaces against abrasion, peeling, fuel resistant, and denting...

3:1 Shrink Ratio & Dual Wall

When heating with a heat gun or other heater, the tubing will recover to 1/3 of its original diameter, which makes it possible to repair most damaged cable jackets without removing connectors. The dual wall tube provides better rigidity and abrasion. The double thick polyolefin tubing secures durable safe for projects.

Heat Activated Adhesive Lined

Our waterproof tubing has an internal adhesive layer. When heating, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat-activated glue strongly adheres to wires, terminals, or any other surfaces.
