Why Choose the Partex HSMB64BLUE 2:1 Blue Heat Shrink Tubing?
The Partex HSMB64BLUE is a versatile and reliable blue heat shrink tubing designed to provide electrical insulation, cable protection and a neat, professional finish to wiring installations. Featuring a 2:1 shrink ratio, this tubing contracts to approximately half its original internal diameter when heated, allowing it to fit securely around suitably sized cables, wires and electrical connections.
As part of the Partex HSMB heat shrink tubing range, HSMB64BLUE is suitable for cable insulation, wire protection, conductor identification and general electrical assembly work. Its blue finish supports colour-coded cable management, helping installers distinguish wiring groups and identify conductors in electrical panels, machinery and industrial automation systems.
With a nominal supplied internal diameter of 6.4 mm, a fully recovered internal diameter of approximately 3.2 mm and a 12 m pack length, this blue heat shrink tubing offers a practical solution for electrical contractors, panel builders, maintenance engineers and industrial automation specialists. Its cut-to-length format makes it particularly useful for cable harnesses, insulated connections and colour-coded wiring assemblies.

Reliable Cable Insulation and Colour-Coded Wire Protection
Heat shrink tubing provides a practical method of insulating, protecting and identifying electrical wiring. When suitable heat is applied, the tubing contracts around the cable or component, creating a close-fitting sleeve that helps protect against abrasion, handling damage and accidental contact with covered conductive parts. The Partex HSMB64BLUE uses a 2:1 shrink ratio, allowing its nominal internal diameter to reduce from 6.4 mm to 3.2 mm when fully recovered.
The blue finish is particularly useful in installations where visual cable identification and consistent colour coding are important. It can be used to identify selected wiring groups, protect appropriately sized cable connections and provide a uniform appearance across electrical assemblies. Where conductor colours have a defined electrical meaning, the tubing must be used in accordance with applicable wiring regulations and site identification standards. For dependable results, the tubing should be selected according to the dimensions of the cable or component and installed using appropriate controlled heating equipment.
Typical Applications
- Electrical cable insulation and protection.
- Colour-coded cable and conductor identification.
- Industrial control panel wiring and cable management.
