ECHS232BLUE Partex 2:1 heat shrink tubing, 3.2/1.6mm, blue, pack 150m

Why Choose the Partex ECHS232BLUE 2:1 Heat Shrink Tubing?

The Partex ECHS232BLUE is a blue 2:1 heat shrink tubing product designed for electrical wire insulation, cable identification and protection of small electrical connections. Featuring a nominal supplied diameter of 3.2 mm and a nominal recovered diameter of 1.6 mm, this tubing provides a practical solution for electrical installation, control panel wiring, electronics assembly and cable harness manufacturing.

With its 2:1 shrink ratio, the ECHS232BLUE is designed to reduce to approximately half its original diameter when correctly heated and allowed to recover fully. This enables the tubing to conform closely around appropriately sized wires and components, creating a neat insulating sleeve. Its distinctive blue colour also supports visual wire identification and colour-coded electrical wiring arrangements.

Supplied in a generous 150 m pack, the Partex ECHS232BLUE is particularly suitable for electrical contractors, panel builders, electronics technicians and cable assembly manufacturers requiring consistent quantities of heat shrink sleeving for repeated installation and production work.

Effective Wire Insulation and Blue Cable Identification

The Partex ECHS232BLUE provides a practical method of insulating and identifying electrical wires using heat-activated tubing. Its nominal supplied diameter of 3.2 mm allows it to be positioned over appropriately sized conductors or components, while its 2:1 recovery ratio enables the tubing to shrink towards a nominal recovered diameter of 1.6 mm when sufficient heat is applied.

For effective installation, the tubing should be selected according to the dimensions of the item being covered, cut to the required length and heated evenly using suitable equipment. The blue colour can support an established electrical wiring identification scheme, while the 150 m supply quantity makes it convenient for workshops and production environments. Applications requiring specific dielectric ratings, operating temperatures, flame classifications or environmental certifications should be checked against the relevant Partex product specifications before installation.
