HellermannTyton HelaShrink 319 Heat Shrink Tubing 2:1, 1.2 mm Supplied Diameter, Black, 1 m Length, 10 Pieces (319-01200)

Heat shrink tubing provides reliable electrical insulation and mechanical protection for wire connections, splices, and cable bundles. This HelaShrink 319 tubing shrinks to half its supplied diameter when heated, creating a tight, durable seal that resists abrasion, chemicals, and UV exposure.

Advantages

Made from cross-linked polyolefin, the tubing is halogen-free and self-extinguishing, making it safe for use in sensitive environments. Its 2:1 shrink ratio ensures a snug fit over irregular shapes, while the wide operating temperature range from -55 °C to +125 °C suits demanding applications.

Suitable for

• Insulating and protecting electrical splices and terminations
• Strain relief for cables and wires
• Bundling and organising wire harnesses
• Mechanical protection against abrasion and impact
