Why Choose the Partex ECHS2381BLUE 2:1 Blue Heat Shrink Tubing?
The Partex ECHS2381BLUE is a practical and versatile 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 an effective solution for covering electrical cables, insulating suitable connections and achieving a neat, professional finish on wiring assemblies and cable harnesses.
Featuring a nominal supplied internal diameter of 38.1 mm and a nominal fully recovered internal diameter of 19 mm, the ECHS2381BLUE offers an approximately 2:1 shrink ratio. When suitable heat is applied, the tubing contracts around appropriately sized cables and components, creating a close-fitting protective covering that helps reduce abrasion, mechanical wear and damage caused by routine handling. Its larger diameter makes it particularly useful for protecting compatible multicore cables, cable bundles, insulated joints and wiring harness assemblies.
The distinctive blue finish provides clear visual identification and supports organised cable management in electrical equipment. Blue is commonly associated with neutral conductor identification in UK and European harmonised electrical installations, making this tubing suitable for appropriate identification applications. Supplied in a convenient 30 m pack, the ECHS2381BLUE is ideal for electrical contractors, control panel manufacturers, industrial maintenance engineers and OEM equipment builders requiring dependable heat shrink sleeving for cable preparation, electrical assembly and maintenance work.

Reliable Electrical Insulation and Cable 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 ECHS2381BLUE 2:1 blue heat shrink tubing has a nominal internal diameter of 38.1 mm before shrinking and a nominal fully recovered diameter of 19 mm. These dimensions make it suitable for appropriately sized larger electrical cables, insulated joints, cable bundles and wiring assemblies. The blue finish provides a consistent appearance and can support conductor identification in electrical systems where blue denotes a neutral conductor, including suitable distribution equipment and control panel installations.
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, colour identification must always follow the applicable wiring standards and installation requirements. Standard heat shrink tubing should not be assumed to provide a waterproof seal unless a suitable sealing construction is specified.
