Why Choose the Partex ECHS21016BLACK 2:1 Black Heat Shrink Tubing?
The Partex ECHS21016BLACK is a large-diameter black heat shrink tubing designed for cable protection, additional electrical insulation, wire sleeving and cable management applications. Featuring a 2:1 shrink ratio and nominal diameters of 101.6 mm before shrinking and 50.8 mm after shrinking, this tubing provides a practical solution for sleeving larger electrical cables, cable bundles and compatible wiring assemblies in industrial and commercial electrical installations.
As part of the Partex ECHS heat shrink tubing range, the ECHS21016BLACK contracts when heat is applied, forming a close-fitting sleeve around appropriately sized cables and electrical components. Its black finish provides a neat, professional appearance, making it suitable for general-purpose cable protection and sleeving applications within industrial machinery, electrical distribution equipment and automation systems.
Supplied in a convenient 15 m pack, the ECHS21016BLACK is suitable for electrical contractors, industrial panel builders, maintenance engineers and OEM equipment manufacturers requiring larger-diameter heat shrink sleeving. Its 101.6 mm supplied diameter and 50.8 mm recovered diameter make it particularly useful for larger compatible cable sizes, cable bundles and electrical connection assemblies where a substantial sleeving diameter is required.
Key Advantages
- 2:1 heat shrink ratio provides effective diameter reduction for close-fitting cable sleeving.
- 101.6 mm supplied diameter reduces to approximately 50.8 mm after unrestricted shrinking.
- Large-diameter format accommodates appropriately sized larger cables, wiring bundles and electrical assemblies.
- Black finish provides a neat and consistent appearance for electrical cable installations.
- 15 m pack length provides a practical supply for larger cable sleeving and maintenance tasks.
- Provides an additional covering that can help protect suitable cables against abrasion and everyday mechanical handling.
- Can be cut to the required length for individual cables, joints and wiring assemblies.
- Suitable for industrial electrical installations, machinery wiring, control systems and electrical maintenance applications.

- 15 m pack length for professional electrical installation requirements.
- Tubular format suitable for cutting into application-specific lengths.
- Heat-activated shrinking provides a close-fitting covering around compatible cables and components.
- Suitable for cable protection, additional electrical insulation and wiring organisation where the tubing's properties meet the installation requirements.
Large-Diameter Cable Protection for Industrial Electrical Systems
Heat shrink tubing is widely used in electrical engineering to provide an additional protective covering around compatible cables, conductors and wiring components. When heat is applied evenly, the tubing contracts around the underlying cable or component, creating a close-fitting sleeve that can help protect against abrasion and everyday mechanical handling. Tubing should be selected according to the cable dimensions and the electrical, thermal and environmental requirements of the installation.
The Partex ECHS21016BLACK combines a practical 2:1 shrink ratio with a substantial supplied diameter, making it suitable for larger electrical installations where standard small-diameter heat shrink sleeving may not accommodate the cable or component. Its nominal 101.6 mm supplied diameter allows installation over appropriately sized larger cables and wiring assemblies, while its 50.8 mm recovered diameter enables the tubing to contract around compatible components.
For electrical contractors, automation engineers and industrial maintenance teams, the 15 m pack provides a convenient supply for repeated large-diameter cable sleeving tasks. The tubing can be cut into shorter sections to suit individual cable assemblies, helping maintain a consistent appearance throughout electrical installations. Before installation, the selected tubing should be checked for adequate clearance over the largest component and a suitable recovered diameter for the intended fit. Where specific insulation ratings, environmental protection or sealing performance are required, the relevant manufacturer technical data should be checked before use.
Typical Applications
- Additional sleeving and protection for larger compatible electrical cables.
- Protection and organisation of appropriately sized cable bundles.
- Industrial machinery and automation equipment cable installations.
- Electrical distribution equipment and switchgear cable assemblies.
- Industrial control cabinet and electrical panel wiring.
- Sleeving of suitable larger cable joints and electrical connections.
- Electrical maintenance, refurbishment and cable management work.
- OEM equipment manufacturing and industrial electrical installations.

Frequently Asked Questions
What is the Partex ECHS21016BLACK heat shrink tubing used for?
The Partex ECHS21016BLACK is used for larger-diameter cable protection, additional electrical sleeving and cable management in industrial electrical installations, machinery wiring, electrical distribution equipment and compatible cable assemblies.
What does the 2:1 shrink ratio mean?
A 2:1 shrink ratio means the tubing can reduce to approximately half its original diameter when heated without an obstruction. The ECHS21016BLACK has a nominal supplied diameter of 101.6 mm and a nominal recovered diameter of 50.8 mm.
How much heat shrink tubing is supplied in one pack?
The Partex ECHS21016BLACK is supplied in a 15 m pack, providing tubing that can be cut to the required lengths for individual cable protection, electrical installation and maintenance tasks.
What are the benefits of black heat shrink tubing?
The black finish provides a neat, consistent appearance for electrical cable sleeving and protection applications. It is particularly useful for general-purpose electrical installations where a uniform cable finish is preferred and specific colour-coded identification is not required.
Where can the Partex ECHS21016BLACK tubing be installed?
This tubing is suitable for appropriately sized cables and wiring components used in industrial machinery, electrical control panels, automation equipment, switchgear, distribution systems and cable assemblies. It is positioned over the component before controlled heat is applied to shrink it into place.
