Heavy-Duty Dual Wall Heat Shrink Tubing | 12mm Diameter, 3:1 Ratio (Red - 1m Length)

Protect, insulate, and fully waterproof your heavy-gauge electrical joins with this premium 12mm Red Dual Wall Heat Shrink Tubing. Supplied in a convenient 1-metre length, this commercial-grade polyolefin tubing features an advanced 3:1 shrink ratio, meaning it collapses down to a tight 4mm diameter to provide a seamless, form-fitting protective barrier over large cable lugs, splices, and battery terminals.

Engineered with an internal hot-melt adhesive lining, the outer wall shrinks tightly under heat while the inner layer melts and flows. This encapsulates the entire joint, creating a permanent, watertight, and dustproof environment seal that completely blocks out moisture, salt, and atmospheric corrosion.

Key Features

  • Advanced 3:1 Shrink Ratio: Highly versatile sizing that easily slides over bulky terminals or lugs and shrinks down small enough to grip the bare cable tightly.

  • Dual Wall Co-Extrusion: Built with a flame-retardant outer layer for ultimate physical toughness and a hot-melt adhesive inner liner for a flawless, watertight seal.

  • Superior Strain Relief: Vastly improves the mechanical strength of the cable transition, absorbing vibrations and physical pulling forces to prevent structural failures.

  • Flame and Chemical Resistant: Manufactured to withstand extreme engine bay environments, resisting fuels, hydraulic oils, acids, and environmental solvents.

  • Industrial Compliance: Crafted to comply with RoHS, REACH, and ISO manufacturing standards, making it the choice for professional trade installations.
