Why Choose the Partex ECHS21016YELLOW 2:1 Heat Shrink Tubing?
The Partex ECHS21016YELLOW is a large-diameter 2:1 heat shrink tubing designed for electrical insulation, cable protection and wire identification in industrial, commercial and electrical engineering applications. Supplied in a distinctive yellow finish, this heat shrink sleeving offers a practical solution for protecting larger electrical cables, covering compatible cable connections and organising substantial wiring assemblies.
Featuring a nominal supplied internal diameter of 101.6 mm and a fully recovered internal diameter of 50.8 mm, the ECHS21016YELLOW provides a 2:1 shrink ratio. When suitable heat is applied, the tubing contracts to approximately half its original internal diameter, allowing it to form a close-fitting protective sleeve around appropriately sized cables, cable bundles and electrical components.
Supplied in a convenient 15 m pack, the Partex ECHS21016YELLOW is particularly suitable for electrical panel builders, wiring harness manufacturers, industrial maintenance engineers and production environments. Its generous supplied diameter makes it useful for sleeving compatible large cable assemblies and components, while the highly visible yellow finish supports colour-coded cable identification and helps distinguish selected wiring groups during installation and maintenance.

Reliable Electrical Insulation and Protection for Large Cable Assemblies
Heat shrink tubing provides a convenient method of insulating electrical conductors, covering compatible cable joints and protecting wiring assemblies. The Partex ECHS21016YELLOW 2:1 heat shrink tubing contracts when suitable heat is applied, allowing the sleeve to conform closely to appropriately sized cables and electrical components. This helps create a neat, organised installation while providing an additional protective layer against everyday mechanical wear.
The 101.6/50.8 mm diameter configuration makes this tubing particularly useful for compatible large-diameter electrical cables, substantial wiring harnesses and cable bundles. Its generous supplied diameter allows it to pass over appropriately sized components and cable assemblies before shrinking. The yellow finish provides strong visual contrast against many common cable sheath colours, making it useful for distinguishing selected cable groups, identifying wiring sections and supporting organised cable management.
For effective installation, ensure the tubing fits over the cable or component before heating and has sufficient recovery to grip it securely. Apply heat evenly using a suitable controlled heat source and follow the manufacturer's installation guidance. The final fit depends on the outside diameter and shape of the sleeved assembly, so the correct tubing size should be selected before installation.
Where yellow sleeving is used for conductor identification, ensure the application complies with relevant wiring standards and site-specific identification requirements. The colour alone should not be relied upon to establish a conductor's electrical function. Heat shrink tubing should also not be assumed to provide a waterproof seal unless the relevant sealing properties have been confirmed.
