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.

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
