164 Pcs Electrical Heat Shrink Kit

This electrical-grade heat shrink kit comprises 164 individual polyolefin tubes, each delivering a dependable 2:1 shrink ratio. Available in five core colours — yellow, blue, black, green and red — and eight inner diameters: 1.0 mm, 2.0 mm, 3.0 mm, 4.0 mm, 6.0 mm, 8.0 mm, 10.0 mm and 14.0 mm. Tube lengths are either 40 mm (ideal for terminal insulation and fine-gauge wires) or 80 mm (recommended for cable boots, connector strain relief and dual-layer protection). Shrink behaviour is thermally controlled: begins at +70°C, completes at +110°C. Approved for long-term service between -55°C and +125°C. Mechanical and electrical characteristics include 10.4 MPa tensile strength and 15 kV/mm dielectric strength. Net package weight is 40 g. Specifically developed for electricians, hobbyists and maintenance teams requiring durable insulation, clean wire organisation, traceable colour coding and physical protection against chafing, moisture and dust ingress. Frequently applied in home automation setups, EV battery interconnects, robotics wiring, HVAC control systems and school electronics labs. The included quantities mirror documented field usage: 60 pcs of 1.0×40 mm (yellow/black/red/green), 30 pcs of 2.0×40 mm (yellow/black/red/blue), 20 pcs of 3.0×40 mm (yellow/black/red/green), 16 pcs of 4.0×40 mm (yellow/black/red/blue), 12 pcs of 6.0×40 mm (yellow/black/red/green), 10 pcs of 8.0×80 mm (yellow/black/red/blue), and 8 pcs each of 10.0×80 mm and 14.0×80 mm (yellow/black/red/green/blue) — balancing breadth with usability.
