Why Choose the Partex HS2191BLACK 2:1 Black Heat Shrink Tubing?
The Partex HS2191BLACK is a versatile and practical black heat shrink tubing designed for electrical insulation, cable protection, wire identification and professional cable management. Featuring a 2:1 shrink ratio, this tubing reduces from a nominal supplied internal diameter of 19.1 mm to 9.5 mm when fully recovered, providing a close-fitting protective sleeve around appropriately sized cables, wire bundles and electrical components.
Manufactured by Partex, a recognised specialist in cable identification and electrical installation products, this black heat shrink tubing provides an effective solution for protecting electrical connections and improving the finish of cable assemblies. Its black colour provides a discreet, professional appearance, making it particularly suitable for electrical control panels, industrial machinery, cable harnesses and maintenance applications where a consistent finish is required.
Supplied in a convenient 50 m pack, the HS2191BLACK is well suited to electrical contractors, control panel builders, industrial manufacturers and maintenance engineers requiring a bulk supply of protective sleeving. With its 19.1 mm supplied diameter and 9.5 mm nominal recovered diameter, it is particularly useful for larger conductors, cable bundles, electrical terminations and protective sleeving applications in industrial and commercial environments.

Reliable Electrical Insulation and Cable Protection
Heat shrink tubing is widely used in electrical and industrial installations to provide protective sleeving around conductors, cable connections and electrical components. When suitable heat is applied, the tubing contracts around the underlying component, creating a neat, close-fitting covering that helps protect against abrasion and provides additional electrical insulation where appropriate.
The Partex HS2191BLACK combines a practical 2:1 shrink ratio with a larger 19.1 mm supplied internal diameter, making it particularly useful for applications involving larger cables, grouped conductors and electrical connections. Its black finish provides a consistent appearance across cable assemblies while helping protect the underlying wiring against minor mechanical damage.
Black heat shrink tubing is commonly selected for general-purpose protective sleeving, cable harness assembly and electrical maintenance applications. It can help organise cable bundles, cover suitable connection areas and provide a tidy finish to electrical equipment. Unlike dedicated colour-coded identification sleeving, black tubing is particularly useful where a neutral appearance is preferred and specific conductor identification colours are not required.
For effective installation, select tubing with a supplied internal diameter large enough to pass over the intended cable, connector or component and a recovered diameter suitable for the required fit. Cut the tubing to length and apply controlled, even heat using an appropriate heat gun, following the manufacturer's installation recommendations and avoiding excessive heating of the underlying cable insulation. Where a moisture-resistant seal or environmental barrier is required, a suitably specified sealing product should be selected rather than assuming standard heat shrink tubing is waterproof.
