Why Choose the Partex HSMB254BLUE 2:1 Blue Heat Shrink Tubing?

The Partex HSMB254BLUE is a versatile and reliable blue heat shrink tubing designed for electrical insulation, cable identification and protection of wires and electrical connections. Featuring a 2:1 shrink ratio, this tubing contracts when heated to provide a neat, close-fitting protective covering around compatible cables, conductors and electrical components.

As part of the Partex HSMB heat shrink tubing range, it provides a practical solution for electrical installers, maintenance engineers and control panel builders requiring effective cable protection and identification. Its blue colour supports clear visual identification and colour-coded wiring installations, while its heat-activated shrinking action enables a professional finish on cable assemblies and electrical connections.

With a nominal supplied diameter of 25.4 mm, a recovered diameter of 12.7 mm and a 5 m pack length, the HSMB254BLUE is suitable for insulating and protecting appropriately sized larger cables, cable bundles and electrical connections in industrial machinery, electrical control panels and general wiring applications.

Key Advantages

  • 2:1 heat shrink ratio provides a close-fitting protective sleeve around compatible cables and electrical connections.
  • 25.4 mm nominal supplied diameter accommodates larger cables and appropriately sized wiring assemblies.
  • 12.7 mm nominal recovered diameter enables effective insulation and protection when correctly installed.
  • Blue colour supports visual identification and colour-coded electrical wiring systems.
  • 5 m pack length provides convenient material for multiple electrical installation tasks.
  • Helps protect wiring against abrasion and minor mechanical damage.
  • Cut-to-length tubing offers flexibility for different cable sizes and installation requirements.

Key Features

  • Partex HSMB heat shrink tubing series.
  • 2:1 nominal shrink ratio.
  • 25.4 mm diameter before shrinking.
  • 12.7 mm nominal diameter after shrinking.
  • Blue finish for visual cable identification and colour coding.
  • 5 m pack suitable for electrical installation and maintenance applications.
  • Heat-activated shrinking for a neat and close-fitting protective covering.
  • Suitable for cable insulation, wire protection and cable bundle identification.
  • Can be cut into individual lengths to suit specific wiring requirements.

Reliable Cable Insulation and Protection for Industrial Electrical Systems

Heat shrink tubing is widely used in electrical engineering to provide insulation, protect conductors and improve the organisation of cable assemblies. When suitable heat is applied, the tubing contracts around the underlying cable or component, creating a close-fitting sleeve that helps reduce exposure to abrasion and everyday handling damage.

The Partex HSMB254BLUE is designed for applications where blue cable identification and heat shrink protection are required. Its 2:1 shrink ratio makes it suitable for appropriately sized cables and electrical connections, while the convenient 5 m pack allows electrical engineers and installers to cut the tubing to the required length for each installation. The larger nominal supplied diameter makes it particularly useful for cable bundles, larger conductors and electrical wiring assemblies where smaller heat shrink tubing would not provide sufficient clearance before shrinking.

Typical Applications

  • Electrical cable insulation and wire protection.
  • Control panel wiring and electrical cabinet assembly.
  • Industrial machinery and automation wiring.
  • Blue cable identification and colour-coded wiring systems.
  • Protection of larger cables and compatible cable bundles.
  • Insulation of compatible cable joints and electrical terminations.
  • Electrical maintenance, servicing and repair applications.
  • OEM equipment manufacturing and cable harness assembly.
