ECHS224BLUE Partex 2:1 heat shrink tubing, 2.4/1.2mm, blue, pack 150m

Why Choose the Partex ECHS224BLUE 2:1 Blue Heat Shrink Tubing?

The Partex ECHS224BLUE is a blue 2:1 heat shrink tubing product designed for electrical wire insulation, cable identification and protection of suitable electrical connections. Featuring a nominal diameter of 2.4 mm before shrinking and 1.2 mm after shrinking, this tubing provides a practical solution for covering small-diameter wires and components in electrical installations, control panels and industrial equipment.

With its 2:1 shrink ratio, the tubing contracts to approximately half its original diameter when heated under appropriate conditions. This allows it to fit around compatible wires and components, providing a close-fitting protective covering after shrinking. Its blue finish can also support visual cable identification and colour-coded wiring arrangements where appropriate.

Supplied in a 150 m pack, the Partex ECHS224BLUE is particularly suitable for electrical panel builders, cable assembly manufacturers, industrial maintenance teams and installers requiring substantial quantities of small-diameter heat shrink tubing for repeated insulation, cable identification and termination work.

Key Advantages

• 2:1 shrink ratio allows the tubing to reduce to approximately half its original diameter.

Reliable Wire Insulation and Colour Identification for Electrical Assemblies

Heat shrink tubing is widely used in electrical installations to provide a close-fitting covering around conductors, wire joints and small components. When selected in the correct size and installed using suitable heating equipment, the tubing contracts around the underlying surface to help provide insulation, mechanical protection and a tidy cable assembly finish. Coloured heat shrink tubing can also support visual identification of conductors and cable assemblies, making wiring easier to organise and maintain.

The Partex ECHS224BLUE features a 2.4 mm supplied diameter and a 1.2 mm recovered diameter, making it suitable for applications where small-diameter blue heat shrink tubing is required. Installers should ensure that the tubing can pass over the component before shrinking and that its recovered diameter is appropriate for the finished assembly. Heating should follow the manufacturer's recommendations to avoid damaging the tubing or underlying cable insulation. Where conductor identification is safety-critical, the colour must be used in accordance with applicable wiring standards rather than treated as a universal identification method.

Typical Applications

• Insulation of small electrical wires and conductors.
• Protection of compatible electrical connections and wire joints.
• Industrial control panel wiring and assembly.
• Colour-coded electrical cable identification.
• Electrical cable harness manufacturing.
• Electronic equipment wiring and component protection.
• Automation equipment and instrumentation wiring.
• Electrical equipment manufacturing and OEM assembly.
• Repair and refurbishment of suitable cable insulation.
• High-volume electrical installation and maintenance work.
