Why Choose the Partex ECHS248BLACK 2:1 Black Heat Shrink Tubing?
The Partex ECHS248BLACK is a professional black 2:1 heat shrink tubing designed for electrical wire insulation, cable protection, conductor sleeving and general wiring applications. Featuring a nominal supplied diameter of 4.8 mm and a nominal fully recovered diameter of 2.4 mm, this heat shrink sleeving provides a neat, close-fitting covering around suitably sized wires, connections and electrical components.
The 2:1 shrink ratio allows the tubing to recover to approximately half its original internal diameter when heated correctly. This enables the sleeve to conform around compatible conductors, cable joints and wiring assemblies, providing an additional layer of electrical insulation while helping protect covered surfaces against abrasion and general handling wear.
Supplied in a convenient 75 m pack, the ECHS248BLACK is suitable for electrical contractors, control panel builders, equipment manufacturers and maintenance engineers requiring reliable heat shrink sleeving for repeated installation tasks. Its black finish provides a discreet, professional appearance for cable assemblies, electrical panels and equipment wiring.

Reliable 2:1 Heat Shrink Protection for Electrical Cables and Connections
The Partex ECHS248BLACK is designed to create a close-fitting protective sleeve around compatible electrical wires and components. The tubing is positioned over the required section before heat is applied evenly using suitable hot-air equipment. As it warms, the material contracts around the underlying cable or component, helping produce a tidy insulating covering and a professional finish.
With a nominal diameter of 4.8 mm before shrinking and 2.4 mm after full recovery, this tubing is suitable for applications requiring a moderate-diameter heat shrink sleeve. It should be selected so that it passes over the component before heating and contracts sufficiently to grip it afterwards. The 75 m supply length allows installers to cut sleeves to the required dimensions, supporting efficient electrical assembly, maintenance and cable protection work. The tubing should not be assumed to provide a waterproof seal unless the completed assembly has been separately designed and verified for that purpose.
