Why Choose the Partex HS21016YELLOW 2:1 Heat Shrink Tubing?
The Partex HS21016YELLOW is a versatile 2:1 yellow heat shrink tubing designed for electrical insulation, cable protection, cable identification and professional wiring management. Manufactured by Partex, this yellow heat shrink sleeving provides a practical solution for protecting larger-diameter insulated conductors, cable bundles and wiring assemblies in industrial automation systems, electrical control panels and machinery 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 and electrical components. The distinctive yellow finish provides excellent visual contrast, making it particularly useful for identifying designated cable groups, equipment connections and wiring assemblies within organised electrical installations.
With a supplied internal diameter of 101.6 mm and a nominal recovered diameter of 50.8 mm, the HS21016YELLOW is suitable for compatible large-diameter cables, cable bundles and conductor protection applications. Supplied in a convenient 15 m pack, this yellow heat shrink tubing offers a practical solution for electrical contractors, industrial control panel manufacturers, OEM equipment builders and electrical maintenance teams.

Reliable Electrical Insulation and High-Visibility Yellow Cable Protection
Heat shrink tubing such as the Partex HS21016YELLOW 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 101.6 mm supplied internal diameter makes the HS21016YELLOW particularly useful for compatible larger cable assemblies and wiring bundles that require protective sleeving. Its nominal recovery to 50.8 mm enables the tubing to contract around appropriately sized applications, providing a neat and organised finish. Installers should select the tubing according to the dimensions of the complete assembly, including any connectors, joints or other components over which the sleeve must pass.
The bright yellow finish supports high-visibility cable identification in industrial automation, control panel assembly and electrical maintenance environments. Yellow sleeving can be used to distinguish designated wiring groups or equipment connections where this is appropriate under the applicable identification scheme. Supplied in a 15 m pack, the tubing is suitable for repeated installation and manufacturing tasks. Solid yellow sleeving must not be confused with the green/yellow combination reserved for protective earth conductor identification under applicable UK and European wiring conventions.
Typical Applications
- Electrical cable insulation and protection.
- High-visibility identification of compatible cable assemblies.
- Industrial control panel wiring and cable management.
- PLC and automation equipment wiring organisation.
- Protection of compatible large-diameter insulated conductors.
- Cable bundle sleeving and wiring harness protection.
- Industrial machinery wiring and electrical equipment assembly.
- OEM manufacturing, electrical installation and maintenance projects.

Frequently Asked Questions
What is the Partex HS21016YELLOW heat shrink tubing used for?
The tubing is used for electrical insulation, cable protection and cable identification in electrical installations, industrial automation systems, control panels and machinery wiring. Its large supplied diameter makes it suitable for compatible larger cables and wiring bundles, while its yellow finish supports high-visibility identification.
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 HS21016YELLOW has a nominal supplied internal diameter of 101.6 mm and a recovered internal diameter of 50.8 mm.
What size is the Partex HS21016YELLOW tubing?
The tubing has a 101.6 mm supplied internal diameter and a 50.8 mm nominal recovered internal diameter. It is suitable for compatible large-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 HS21016YELLOW is supplied in a 15 m pack, providing a convenient quantity for larger cable protection, electrical installation, cable identification and maintenance applications.
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, cable bundles 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.
