Why Choose the Partex ECHS248BLUE 2:1 Blue Heat Shrink Tubing?
The Partex ECHS248BLUE is a versatile 2:1 blue heat shrink tubing designed for electrical insulation, cable protection and colour-coded wire identification in industrial and commercial electrical installations. Part of the Partex ECHS heat shrink tubing range, this sleeving provides a practical solution for protecting electrical conductors, insulating connections and achieving a neat, professional finish on cable assemblies.
Featuring a nominal supplied internal diameter of 4.8 mm and a nominal fully recovered internal diameter of 2.4 mm, the ECHS248BLUE offers a 2:1 shrink ratio. When suitable heat is applied, the tubing contracts around appropriately sized conductors and components, creating a close-fitting protective covering that helps reduce abrasion, mechanical wear and damage caused by routine handling.
The distinctive blue finish provides clear visual identification and supports organised cable management in electrical equipment. Supplied in a convenient 75 m pack, the ECHS248BLUE is suitable for electrical contractors, control panel manufacturers, industrial maintenance engineers and OEM equipment builders requiring dependable heat shrink sleeving for wiring, cable preparation and electrical assembly applications.

Reliable Electrical Insulation and Cable Identification for Industrial Wiring
Heat shrink tubing is widely used in electrical engineering, industrial automation and electronics manufacturing to provide an insulating and protective covering around wires, electrical connections and cable assemblies. When heated using a suitable controlled heat source, the tubing contracts in diameter to fit around the underlying conductor or component. This creates a neat protective sleeve that helps reduce exposure to abrasion, handling damage and mechanical wear.
The Partex ECHS248BLUE 2:1 blue heat shrink tubing has a nominal internal diameter of 4.8 mm before shrinking and a nominal fully recovered diameter of 2.4 mm. These dimensions make it suitable for appropriately sized electrical conductors, soldered connections and wiring assemblies. The blue finish provides a consistent appearance and can support cable identification schemes in control panels, automation systems and industrial equipment.
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 electrical installations, blue is associated with neutral conductor identification, so colour selection should follow the applicable wiring requirements. Standard heat shrink tubing should not be assumed to provide a waterproof seal unless a suitable sealing construction is specified.
