Dual Wall Glue-Lined Heat Shrink Tubing – Waterproof Cable Protection in 6 Sizes

Keep your wiring neat, secure, and fully protected with this Dual Wall Heat Shrink Tubing. Featuring a powerful 4:1 shrink ratio and an inner adhesive (hot-melt glue) lining, this tubing creates an airtight, waterproof seal around cables, connectors, and splices — ideal for automotive, marine, electrical, and DIY applications. Available in six diameter options: 4mm, 6mm, 8mm, 12mm, 16mm, and 20mm.

Made in Mainland China.

Why Choose Dual Wall Heat Shrink Tubing?

  • 4:1 Shrink Ratio: Shrinks to a quarter of its original diameter for a snug, reliable fit over a wide range of cable sizes.
  • Inner Glue Layer: The hot-melt adhesive liner melts when heated, flowing around irregularities to form a watertight, corrosion-resistant seal — far superior to single-wall tubing.
  • PE Construction: High-quality polyethylene material delivers excellent electrical insulation, mechanical abrasion resistance, and durability.
  • 6 Size Options: Diameters of 4mm, 6mm, 8mm, 12mm, 16mm, and 20mm mean you'll always have the right fit for any cable or connector.
  • Versatile Use: Perfect for automotive wiring, marine wiring harnesses, outdoor electrical connections, wire splices, and hobbyist or workshop projects.
  • Easy to Apply: Simply slide over the cable and apply even heat from a heat gun to shrink and seal in seconds.

Frequently Asked Questions

Q: What is the shrink ratio of this dual wall heat shrink tubing?

A: This heat shrink tubing features a 4:1 shrink ratio, meaning it shrinks to one-quarter of its original diameter when heat is applied. This makes it suitable for covering a wide variety of cable and connector sizes with a secure, snug fit.

Q: Do I need a special tool to apply this heat shrink tubing?

A: A standard heat gun is recommended for best results. Apply even heat along the length of the tubing and it will shrink down while the inner glue layer melts to create a waterproof seal. A lighter can be used in a pinch, but a heat gun provides more even and controlled shrinkage.

Q: Is this tubing waterproof?

A: Yes. The dual wall construction includes a hot-melt adhesive inner lining that flows and seals around the cable when heated, creating an excellent waterproof and moisture-resistant barrier — ideal for outdoor, automotive, and marine environments.

Q: Which diameter size should I choose?

A: Choose a diameter that is slightly larger than the widest point of the cable or connector you need to cover. For example, use the 4mm or 6mm for thin gauge wires, 8mm or 12mm for medium cables and connectors, and 16mm or 20mm for larger bundles or heavy-duty connectors. Because of the 4:1 ratio, each size accommodates a broad range of cable dimensions.
