BKL Electronic 074283 Heat Shrink Tubing 6.4 mm Black 2:1 100 m

Heat shrink tubing with a 2:1 shrink ratio, supplied in black polyolefin with a 6.4 mm diameter that recovers to 3.2 mm. The 100 m roll provides reliable electrical insulation, wire bundling, and strain relief for professional installations.

Advantages

Polyolefin construction offers good chemical resistance and UV resistance. The tubing shrinks at 70 °C and fully recovers at 110 °C, operating from -55 °C to +125 °C. Dielectric strength of 20 kV/mm and a 600 V rating ensure dependable insulation.

Suitable for

• Electrical insulation of splices and terminations
• Wire bundling and harness organization
• Strain relief for connectors and cables
