Why Choose the Partex HS2381BLUE 2:1 Heat Shrink Tubing?
The Partex HS2381BLUE is a practical and versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, wire identification and professional cable management. Manufactured by Partex, this blue heat shrink sleeving provides a convenient solution for protecting insulated conductors, larger cable assemblies and electrical connections in industrial automation systems, control panels and electrical installations.
Featuring a 2:1 shrink ratio, the tubing contracts to approximately half its original internal diameter when heated appropriately. This allows it to form a close-fitting protective sleeve around compatible cables, cable bundles and electrical components. The distinctive blue colour supports visual cable identification, helping engineers and installers distinguish designated wiring groups, circuits and equipment connections within organised electrical installations.
With a supplied internal diameter of 38.1 mm and a nominal recovered diameter of 19 mm, the HS2381BLUE is suitable for a range of larger-diameter cables, wiring assemblies and conductor protection applications. Supplied in a convenient 30 m pack, this blue heat shrink tubing offers a practical solution for electrical contractors, control panel builders, OEM manufacturers and industrial maintenance teams.

Reliable Electrical Insulation and Colour-Coded Cable Protection
Heat shrink tubing such as the Partex HS2381BLUE provides a convenient method of insulating and protecting 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 and handling damage. The 2:1 shrink ratio provides flexibility when selecting tubing for compatible cable and conductor sizes. For effective installation, the tubing must be large enough to pass over the application before shrinking while having sufficient recovery to grip the finished assembly.
The blue finish makes the HS2381BLUE particularly useful for colour-coded cable identification and organised electrical installations. Blue sleeving can help distinguish selected wiring groups, cable assemblies or equipment connections where the colour is appropriate under the applicable identification scheme. Its 30 m pack supports repeated installation tasks and electrical assembly work, making it a practical choice for industrial automation, control panel manufacturing and electrical maintenance. Where blue is used to identify neutral conductors under applicable wiring standards, it should be applied consistently with the relevant installation requirements.
Typical Applications
- Electrical cable insulation and protection.
- Industrial control panel wiring and assembly.
- PLC and automation equipment cable management.
- Blue cable identification and colour-coded wiring systems.
- Protection of compatible larger-diameter conductors and insulated connections.
- Cable harness assembly and equipment maintenance.
- OEM machinery wiring and industrial electrical manufacturing.

Frequently Asked Questions
What is the Partex HS2381BLUE heat shrink tubing used for?
The tubing is used for electrical insulation, cable protection and wire identification in electrical installations, industrial automation systems, control panels and machinery wiring. Its blue finish can also help distinguish designated wiring groups and cable assemblies.
What does the 2:1 shrink ratio mean?
A 2:1 shrink ratio means the tubing can shrink to approximately half its original internal diameter when sufficient heat is applied. The HS2381BLUE has a nominal supplied internal diameter of 38.1 mm and a recovered internal diameter of 19 mm.
What size is the Partex HS2381BLUE tubing?
The tubing has a 38.1 mm supplied internal diameter and a 19 mm nominal recovered internal diameter. It is suitable for compatible larger-diameter cable and wiring applications where the tubing can pass over the assembly before shrinking and recover sufficiently to achieve a close fit.
How much heat shrink tubing is supplied?
The Partex HS2381BLUE is supplied in a 30 m pack, providing a convenient quantity for electrical installation, control panel building, cable identification and maintenance work.
What are the benefits of blue heat shrink tubing?
Blue heat shrink tubing provides clear visual identification while helping organise and protect cables within electrical installations. It can distinguish designated wiring groups or equipment connections where blue is appropriate under the applicable identification scheme. The tubing also provides an additional protective sleeve against abrasion and handling damage. Conductor identification must follow relevant wiring standards and site requirements.
