Why Choose the Partex HS2381BROWN 2:1 Heat Shrink Tubing?
The Partex HS2381BROWN is a versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, conductor identification and professional cable management. Manufactured by Partex, this brown heat shrink sleeving provides a practical 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 brown colour supports visual conductor identification and can help distinguish designated wiring groups or electrical circuits in accordance with applicable wiring standards.
With a supplied internal diameter of 38.1 mm and a nominal recovered diameter of 19 mm, the HS2381BROWN is suitable for a range of larger-diameter cables, wiring assemblies and conductor protection applications. Supplied in a convenient 30 m pack, this brown heat shrink tubing offers a practical solution for electrical contractors, control panel builders, OEM manufacturers and industrial maintenance teams.

Reliable Electrical Insulation and Brown Conductor Identification
Heat shrink tubing such as the Partex HS2381BROWN 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 brown finish makes the HS2381BROWN particularly useful for colour-coded electrical installations and conductor identification. Under current UK and harmonised European wiring conventions, brown is used to identify a line conductor in single-phase AC installations and the L1 line conductor in three-phase systems. Brown sleeving can therefore assist with identifying appropriate conductors and connections when installed in accordance with the relevant standards. The 30 m pack supports repeated installation tasks in industrial automation, control panel manufacturing and electrical maintenance. Colour identification should always be verified against the installation's wiring documentation and applicable requirements.
Typical Applications
- Electrical cable insulation and protection.
- Brown line conductor identification in appropriate AC electrical installations.
- Industrial control panel wiring and assembly.
- PLC and automation equipment cable management.
- Colour-coded identification of compatible cable assemblies and connections.
- Protection of larger-diameter insulated conductors and cable bundles.
- OEM machinery wiring, cable harness assembly and electrical maintenance.

Frequently Asked Questions
What is the Partex HS2381BROWN heat shrink tubing used for?
The tubing is used for electrical insulation, cable protection and conductor identification in electrical installations, industrial automation systems, control panels and machinery wiring. Its brown finish can also help identify designated line conductors where required by the applicable wiring standards.
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 HS2381BROWN has a nominal supplied internal diameter of 38.1 mm and a recovered internal diameter of 19 mm.
What size is the Partex HS2381BROWN 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 HS2381BROWN is supplied in a 30 m pack, providing a convenient quantity for electrical installation, control panel building, conductor identification and maintenance work.
Why is brown heat shrink tubing used for conductor identification?
Brown heat shrink tubing can be used to identify line conductors in accordance with UK and harmonised European wiring conventions. Brown is the recognised colour for the line conductor in single-phase AC systems and L1 in three-phase systems. The tubing also provides a protective sleeve against abrasion and handling damage, but conductor identification must follow the applicable wiring standards and installation documentation.
Trusted Cable Identification and Protection from Partex
Partex cable identification and electrical installation products support organised, dependable wiring systems. The HS2381BROWN 2:1 heat shrink tubing provides a practical solution for insulating, protecting and identifying compatible larger-diameter cables and conductors in industrial automation, control panel assembly and electrical maintenance applications.
