Why Choose the Partex ECHS21016GREY 2:1 Grey Heat Shrink Tubing?
The Partex ECHS21016GREY is a versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, wire identification and professional cable management applications. Part of the Partex ECHS heat shrink tubing range, this grey tubing provides a practical solution for protecting electrical connections, insulating conductors and organising large cable assemblies in industrial, commercial and electrical installation environments.
Designed for general-purpose electrical protection, the tubing contracts when heated to form a close-fitting protective sleeve around cables, wires and compatible components. Its 2:1 shrink ratio allows it to reduce to approximately half its original diameter, helping provide coverage over cable joints, terminations and wiring assemblies. The neutral grey colour also supports cable identification, colour-coded wiring and organised electrical installations.
With a nominal supplied diameter of 101.6 mm, a recovered diameter of approximately 50.8 mm and a convenient 15 m pack, the ECHS21016GREY is particularly suitable for large cables, wiring harnesses and substantial cable bundles. Its bulk supply format allows tubing to be cut to the required length, reducing waste and supporting efficient installation by electrical contractors, panel builders and maintenance engineers.

Reliable Cable Insulation and Electrical Protection
Heat shrink tubing is widely used in electrical engineering to provide insulation and mechanical protection around conductors, cable joints and wiring assemblies. When controlled heat is applied, the tubing contracts around the underlying component, creating a neat protective covering that helps reduce exposure to abrasion and handling damage.
The Partex ECHS21016GREY combines a practical 2:1 shrink ratio with a generous 15 m pack length, making it particularly useful for large-diameter cable preparation and electrical assembly tasks. The tubing can be cut to suit individual installation requirements, while its grey finish helps maintain consistent identification throughout wiring systems. For best results, select tubing that fits over the largest component before shrinking and recovers sufficiently to grip the intended cable or connection.
For electrical installations requiring specific conductor identification, the tubing colour should be selected in accordance with applicable wiring regulations and site identification requirements. Grey sleeving may be used as part of an appropriate conductor identification scheme, but colour alone should not be relied upon without confirming the relevant installation standards.
Typical Applications
- Electrical insulation and protection of large power cables.
- Industrial control panel wiring and cable assembly.
- Protection of large cable joints and electrical terminations.
- Grey colour coding and identification of wiring circuits where appropriate.
- Large cable bundling and wiring harness organisation.
- Electrical maintenance, repair and refurbishment work.
- Machinery wiring and industrial automation installations.
- General-purpose cable protection in workshops and manufacturing facilities.
