Why Choose the Partex HS2381YELLOW 2:1 Heat Shrink Tubing?
The Partex HS2381YELLOW is a versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, conductor identification and professional cable management. Manufactured by Partex, this yellow 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 yellow 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 HS2381YELLOW is suitable for a range of larger-diameter cables, wiring assemblies and conductor protection applications. Supplied in a convenient 30 m pack, this yellow heat shrink tubing offers a practical solution for electrical contractors, control panel builders, OEM manufacturers and industrial maintenance teams.
Key Advantages
- 2:1 heat shrink ratio provides a close-fitting protective sleeve when correctly installed.

Reliable Electrical Insulation and High-Visibility Cable Identification
Heat shrink tubing such as the Partex HS2381YELLOW 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 bright yellow finish makes the HS2381YELLOW particularly useful for high-visibility cable identification and organised electrical installations. Yellow 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 in industrial automation, control panel manufacturing and electrical maintenance. Solid yellow sleeving must not be confused with the green/yellow colour combination reserved for protective earth conductors under applicable UK and European wiring conventions.
Typical Applications
- Electrical cable insulation and protection.
- Industrial control panel wiring and assembly.
- PLC and automation equipment cable management.
- Yellow cable identification and colour-coded wiring systems.
- High-visibility identification of compatible cable assemblies.
- 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 HS2381YELLOW 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 bright yellow 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 HS2381YELLOW has a nominal supplied internal diameter of 38.1 mm and a recovered internal diameter of 19 mm.
What size is the Partex HS2381YELLOW 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 HS2381YELLOW 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 yellow heat shrink tubing?
Yellow heat shrink tubing provides high-visibility cable identification while helping organise and protect cables within electrical installations. It can distinguish designated wiring groups or equipment connections where yellow is appropriate under the applicable identification scheme. Solid yellow sleeving is different from the green/yellow combination used for protective earth conductor identification, and conductor marking must follow relevant wiring standards.
Trusted Cable Identification and Protection from Partex
Partex cable identification and electrical installation products support organised, dependable wiring systems. The HS2381YELLOW 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.
