Tubo termorretrátil HellermannTyton 300-30160 3:1, 3 mm, preto, 10 m

Heat shrink tubing with 3:1 shrink ratio, supplied internal diameter 3 mm, recovered internal diameter 1.5 mm, black, 10 m length. Made of cross-linked polyolefin, it provides electrical insulation, mechanical protection, bundling, and strain relief.

Advantages

Cross-linked polyolefin material offers good chemical resistance and UV resistance for black tubing. The 3:1 shrink ratio allows coverage of irregular shapes and connectors. Dielectric strength >20 kV/mm provides reliable electrical insulation. Operating temperature range from -55°C to +125°C suits harsh environments. UL224 VW-1 flammability rating ensures self-extinguishing properties.

Suitable for

• Electrical insulation of wires and connections
• Mechanical protection against abrasion and impact
• Bundling and organizing cables
• Strain relief for connectors and terminations
