Dual Wall Adhesive Heat Shrink Tubing – Professional Cable Protection

Keep your wiring neat, secure, and fully insulated with this Dual Wall Heat Shrink Tubing with Adhesive Glue Lining. Engineered from high-quality polyethylene (PE) with a 4:1 shrink ratio, this tubing forms a waterproof, airtight seal around cables, connectors, and wire splices — making it an essential addition to any electrical or DIY toolkit.

Available in six versatile diameters — 4mm, 6mm, 8mm, 12mm, 16mm, and 20mm — so you can protect everything from delicate sensor wires to heavy-duty power cables.

Made in Mainland China.

Key Features

  • 4:1 Shrink Ratio: Shrinks to one-quarter of its original diameter for a snug, professional fit on a wide range of cable sizes.
  • Dual Wall Construction: Outer PE shell provides mechanical protection and electrical insulation; inner hot-melt adhesive layer bonds tightly for a waterproof, moisture-resistant seal.
  • Six Size Options: 4mm, 6mm, 8mm, 12mm, 16mm, and 20mm supply diameter — suitable for thin signal wires up to thick power cables and conduit bundles.
  • Electrical Insulation: Keeps bare connections safely insulated to prevent short circuits, corrosion, and accidental contact.
  • Heat Activated: Simply apply a heat gun or torch evenly along the tube — no special tools required.
  • Versatile Use: Ideal for automotive wiring, marine and outdoor cabling, home electrical repairs, robotics, bicycle wiring, and workshop projects.
  • Durable PE Material: Resistant to oils, chemicals, abrasion, and UV exposure for long-lasting protection in demanding environments.

Frequently Asked Questions

Q: What does the 4:1 shrink ratio mean for dual wall heat shrink tubing?

A: A 4:1 shrink ratio means the tubing will shrink to one-quarter of its original inner diameter when heat is applied. This makes it ideal for covering irregular shapes, stepped connections, or bundled cables where a standard 2:1 ratio tube may not achieve a tight enough seal.

Q: How do I apply dual wall adhesive heat shrink tubing?

A: Slide the appropriately sized tubing over the cable or connector you want to protect. Using a heat gun, apply even heat along the length of the tube, working from the centre outward. The outer PE layer will shrink while the inner adhesive layer melts and flows to create a waterproof, airtight bond around the cable.

Q: Which size heat shrink tube should I choose?

A: Select a tube whose pre-shrink inner diameter is slightly larger than the cable or connector you need to cover. For example, for a 5mm cable, the 8mm tube would be appropriate. After shrinking at 4:1, it will form a tight, secure seal.

Q: Is this heat shrink tubing suitable for outdoor and marine use?

A: Yes. The dual wall construction with a hot-melt adhesive inner lining creates a moisture-resistant, waterproof seal, making it well suited for outdoor, automotive, marine, and other environments exposed to moisture, oils, and chemicals.
