ECHS232BLACK Partex 2:1 heat shrink tubing, 3.2/1.6mm, black, pack 150m

Why Choose the Partex ECHS232BLACK 2:1 Black Heat Shrink Tubing?

The Partex ECHS232BLACK is a versatile and reliable 2:1 black heat shrink tubing designed for electrical insulation, cable protection and professional wire finishing 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 organising wiring in control panels, machinery and electronic equipment.

Featuring a nominal supplied internal diameter of 3.2 mm and a fully recovered internal diameter of approximately 1.6 mm, the ECHS232BLACK 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 unwanted exposure of insulated connection areas.

The black finish provides a neat, discreet appearance suitable for professional electrical assemblies and cable harnesses. Supplied in a generous 150 m pack, the ECHS232BLACK is particularly suitable for electrical contractors, industrial maintenance engineers, control panel manufacturers and OEM equipment builders requiring consistent cable sleeving for high-volume wiring and assembly applications.

Reliable Electrical Insulation and Cable Protection 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 small components. When heated using a suitable controlled heat source, the tubing contracts in diameter to fit around the underlying conductor or assembly. This creates a neat protective covering that helps reduce exposure to abrasion, handling damage and mechanical wear.

The Partex ECHS232BLACK 2:1 black heat shrink tubing has a nominal internal diameter of 3.2 mm before shrinking and a nominal fully recovered diameter of 1.6 mm. This makes it suitable for appropriately sized electrical wires, soldered joints and cable assemblies. Its black finish provides a consistent appearance for wiring installations where discreet cable protection and a professional finish are required.

For dependable results, the tubing should be selected with sufficient initial diameter to pass over the largest part of the assembly and an appropriate recovered diameter to achieve the required fit. Heat should be applied evenly using suitable equipment, avoiding excessive temperatures that could damage the tubing or underlying insulation. Standard heat shrink tubing should not be assumed to provide a waterproof seal unless an appropriate sealing construction is specified, and its suitability for any particular electrical insulation duty should be assessed against the installation requirements.
