Why Choose the Partex ECHS21016BLUE 2:1 Blue Heat Shrink Tubing?
The Partex ECHS21016BLUE is a large-diameter 2:1 blue heat shrink tubing designed for electrical insulation, cable protection and colour-coded conductor identification in industrial and commercial electrical installations. Part of the Partex ECHS heat shrink tubing range, this protective sleeving provides a practical solution for covering large electrical cables, protecting insulated connections and achieving a neat, professional finish on cable assemblies, wiring harnesses and electrical equipment.
Featuring a nominal supplied internal diameter of 101.6 mm and a nominal fully recovered internal diameter of 50.8 mm, the ECHS21016BLUE offers a 2:1 shrink ratio. When suitable heat is applied, the tubing contracts around appropriately sized cables and components, forming a close-fitting protective covering that helps reduce abrasion, mechanical wear and damage caused by routine handling. Its substantial diameter makes it particularly useful for sleeving compatible large multicore cables, cable bundles, insulated connections and wiring harness assemblies.
The distinctive blue finish supports clear cable identification and organised electrical wiring systems. Blue is commonly associated with neutral conductor identification in UK and European harmonised electrical installations, making this tubing useful for appropriate conductor marking applications. Supplied in a convenient 15 m pack, the ECHS21016BLUE is suitable for electrical contractors, control panel manufacturers, industrial maintenance engineers and OEM equipment builders requiring dependable large-diameter heat shrink sleeving for cable preparation, electrical assembly and maintenance work.

Reliable Large-Diameter Cable Protection and Conductor Identification for Industrial Wiring
Heat shrink tubing is widely used in electrical engineering, industrial automation and control panel manufacturing to provide an insulating and protective covering around cables, electrical connections and wiring assemblies. When heated using a suitable controlled heat source, the tubing contracts in diameter to fit around the underlying cable or component. This creates a neat protective sleeve that helps reduce exposure to abrasion, handling damage and mechanical wear while supporting professional cable management.
The Partex ECHS21016BLUE 2:1 blue heat shrink tubing has a nominal internal diameter of 101.6 mm before shrinking and a nominal fully recovered diameter of 50.8 mm. These dimensions make it suitable for appropriately sized large electrical cables, insulated joints, multicore cable assemblies and cable bundles. The blue finish provides a consistent appearance and can support conductor identification in electrical systems where blue denotes a neutral conductor, including suitable electrical distribution and industrial control applications.
For dependable results, the tubing should have sufficient initial diameter to pass over the largest part of the assembly and an appropriate recovered diameter to achieve the required fit. Apply heat evenly using suitable equipment and avoid excessive temperatures that could damage the tubing or underlying insulation. In UK harmonised wiring systems, blue is commonly used for neutral conductor identification; however, conductor marking must always follow applicable electrical wiring standards and installation requirements. Standard heat shrink tubing should not be assumed to provide waterproof sealing or adhesive-lined protection unless those properties are specifically confirmed for the product.
