Heavy Duty 3:1 6mm-50mm Heat Shrink Tubing Per Meter – Adhesive Lined Heat Shrink for Battery Cables, Lugs & Electrical Wiring

Razorback 3:1 Glue Lined Heat Shrink Tubing

Razorback 3:1 Glue Lined Heat Shrink Tubing is designed to provide maximum insulation, sealing, and protection for electrical connections in demanding environments. Ideal for automotive, 4WD, marine, caravan, solar, and 12V electrical systems, this heavy-duty adhesive lined heat shrink creates a strong waterproof seal when heated.

Featuring a 3:1 shrink ratio, the tubing shrinks to one third of its original size, allowing it to easily slide over cable lugs, terminals, connectors, and uneven shapes before forming a tight and secure seal. The internal adhesive lining melts during heating, bonding to the cable and connector to create a moisture-resistant barrier that protects against water, dust, vibration, and corrosion.

Manufactured from premium polyolefin heat shrink material, Razorback heat shrink delivers long-lasting durability and professional results. It is perfect for battery cable terminations, inverter wiring, Anderson plug cables, and heavy-duty electrical connections where reliable insulation is essential.

Whether you are wiring a dual battery system, solar setup, marine electrical system, or automotive installation, Razorback glue lined heat shrink tubing ensures strong protection and a clean professional finish.
