Why Choose the Partex ECHS2254GREY 2:1 Heat Shrink Tubing?
The Partex ECHS2254GREY is a grey 2:1 heat shrink tubing product designed for electrical cable insulation, conductor identification and protection of cable connections. Featuring a nominal supplied diameter of 25.4 mm and a nominal fully recovered diameter of 12.7 mm, this tubing provides a practical solution for larger cable assemblies, electrical installations, control panel wiring and industrial maintenance applications.
With its 2:1 shrink ratio, the ECHS2254GREY is designed to reduce to approximately half its original diameter when correctly heated and allowed to recover. This enables the tubing to conform around appropriately sized cables, cable joints and components, creating a neat protective covering. Its distinctive grey colour supports visual cable identification and organised electrical wiring arrangements, including line conductor identification where applicable.
Supplied in a convenient 30 m pack, the Partex ECHS2254GREY is suitable for electrical contractors, panel builders, cable assembly manufacturers and maintenance engineers requiring larger-diameter grey heat shrink sleeving for installation, repair and production work.

Effective Cable Insulation and Grey Conductor Identification
The Partex ECHS2254GREY provides a practical method of insulating and identifying electrical cables using heat-activated tubing. Its nominal supplied diameter of 25.4 mm allows it to be positioned over appropriately sized cables, connections and components, while its 2:1 nominal recovery ratio enables the tubing to shrink towards a nominal recovered diameter of 12.7 mm when sufficient heat is applied.
For effective installation, the tubing should be selected according to the outside diameter of the item being covered, cut to the required length and heated evenly using suitable equipment. The grey colour can support an established electrical conductor identification scheme, including the identification of the L3 line conductor in installations following applicable UK three-phase wiring conventions. The 30 m supply quantity makes it convenient for workshops and production environments. Applications requiring specific dielectric ratings, operating temperatures, flame classifications, adhesive sealing or environmental certifications should be checked against the relevant Partex product specifications before installation.
