Why Choose the Partex HSMB16BLACK 2:1 Black Heat Shrink Tubing?
The Partex HSMB16BLACK is a small-diameter black heat shrink tubing designed for electrical insulation, wire protection, cable identification and professional cable management. Featuring a 2:1 shrink ratio, this tubing reduces from a nominal supplied internal diameter of 1.6 mm to 0.8 mm when fully recovered, providing a close-fitting protective sleeve around appropriately sized small wires, conductors and electrical components.
Manufactured by Partex, a specialist in cable identification and electrical installation products, the HSMB16BLACK offers a practical solution for applications requiring precision heat shrink sleeving. Its black finish provides a neat, consistent appearance, making it suitable for electronic wiring, control panels, instrumentation, small cable assemblies and electrical maintenance applications.
Supplied in a convenient 17 m pack, the Partex HSMB16BLACK is suitable for electrical contractors, electronics technicians, control panel builders, industrial manufacturers and maintenance engineers. With its 1.6 mm supplied internal diameter and 0.8 mm nominal recovered internal diameter, it is particularly useful for fine wires, compact electrical connections and small-diameter protective sleeving applications.

Reliable Electrical Insulation and Small-Diameter Wire Protection
Heat shrink tubing is widely used in electrical and electronic installations to provide protective sleeving around conductors, wire connections and electrical components. When suitable heat is applied, the tubing contracts around the underlying component, creating a close-fitting covering that can help protect against abrasion and provide additional electrical insulation where the product is appropriately specified.
The Partex HSMB16BLACK combines a practical 2:1 shrink ratio with a compact 1.6 mm supplied internal diameter. This makes it particularly useful for applications involving fine electrical conductors, small wiring assemblies and components where larger heat shrink tubing would be unsuitable. Once heated, the tubing contracts towards its nominal recovered internal diameter of 0.8 mm.
The small diameter allows installers to apply protective sleeving to individual fine wires while maintaining a tidy and compact wiring arrangement. This can be especially beneficial in electronic equipment, instrumentation systems, industrial control panels and electrical assemblies where space is limited and careful wire management is important.
Black heat shrink tubing is commonly selected for general-purpose protective sleeving and electrical wire insulation. Its understated appearance helps create a consistent finish across cable assemblies while reducing direct exposure of the underlying wire insulation to minor mechanical wear.
Where conductor identification is required, suitable cable markers, labels or other identification products should be used in accordance with the relevant electrical standards. Black sleeving should not be applied in a way that incorrectly identifies the function of a conductor, particularly in installations using harmonised wiring colours.
For effective installation, select tubing with a supplied internal diameter large enough to pass over the intended wire, connector or component and a recovered diameter suitable for achieving the required fit. Cut the tubing to the required length and position it over the area requiring protection.
Apply controlled, even heat using an appropriate heat gun, following the manufacturer's installation recommendations. Particular care should be taken when heating fine wires and small electronic components to avoid damaging delicate insulation or nearby equipment. Where waterproofing, adhesive bonding or a specified environmental seal is required, select a product with the relevant verified properties rather than assuming standard heat shrink tubing provides a sealed connection.
