PRO POWER - 4:1 Flexible Adhesive Lined Flame Retardant Heat Shrink Tubing - 4mm

The PRO POWER - 4:1 Flexible Adhesive Lined Flame Retardant Heat Shrink Tubing is a premium, professional-grade solution for insulating, sealing, and protecting electrical connections. This dual-layer tubing is engineered for exceptional performance in demanding environments, combining a flame-retardant polyolefin outer layer with a specialised internal adhesive lining.

The low shrink temperature and low shrink point glue activate quickly and reliably, ensuring a tight, uniform seal around wires and components. This creates a robust, permanent barrier that offers outstanding waterproofing and acts as a mechanical strain buffer, protecting connections from vibration, abrasion, and environmental stress.

Key Features & Applications

Ideal for professional automotive, marine, and industrial electrical work, this heat shrink tubing is widely applied for sealing automotive wiring harnesses, preventing gas leaks, managing drain points, and waterproofing multi-strand wire and cable branches. Its flame-retardant properties provide an added layer of safety, helping to prevent the spread of flames in the event of an electrical fault.

The 4:1 shrink ratio allows the tubing to contract significantly, accommodating a wide range of wire gauges and irregular shapes for a secure, custom fit. The flexible construction ensures it can be used in tight spaces and around bends without cracking or compromising the seal. The black colour provides a discreet, professional finish that blends seamlessly with most wiring looms.
