BKL Electronic 074282 Heat Shrink Tubing Black 4.8 mm / 2.4 mm Shrink Ratio 2:1 100 m

Heat shrink tubing made of polyolefin provides reliable electrical insulation and mechanical protection for cables and wires. With a shrink ratio of 2:1, it shrinks to half its original diameter when heated, creating a tight, durable seal. The black tubing is supplied on a 100 m roll, ideal for continuous use in workshops and production environments.

Advantages

Flexible and flame-retardant, this tubing offers excellent dielectric strength of 15 kV/mm. It withstands temperatures from -55 °C to +125 °C and begins shrinking at 70 °C, with full recovery at 110 °C. The recovered wall thickness of approximately 0.5 mm provides robust protection against abrasion and chemicals.

Suitable for

• Electrical insulation of splices and terminations
• Wire bundling and cable management
• Strain relief for connectors and solder joints
• Protection against moisture, dust, and corrosion
