Why Choose the Partex HSMB16BLUE 2:1 Blue Heat Shrink Tubing?
The Partex HSMB16BLUE is a small-diameter blue heat shrink tubing designed for electrical insulation, fine wire protection, conductor 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 HSMB16BLUE offers a practical solution for precision wiring applications. Its distinctive blue finish supports organised cable identification and can be particularly useful in installations where blue is specified for neutral conductor identification under applicable UK and European harmonised wiring conventions.
Supplied in a convenient 17 m pack, the Partex HSMB16BLUE is suitable for electrical contractors, electronics technicians, control panel builders, industrial manufacturers and maintenance engineers. With its compact 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.
The combination of a 2:1 shrink ratio, small tubing diameter and blue colour makes the HSMB16BLUE a practical choice for electrical and electronic assemblies requiring both protective insulation and a clear visual identification system.

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 HSMB16BLUE 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.
The blue colour provides an additional identification benefit. In UK and European harmonised electrical wiring systems, blue is commonly used to identify neutral conductors. Blue heat shrink tubing can therefore support appropriate conductor identification when installed in accordance with the applicable electrical standards and the requirements of the specific installation.
For equipment wiring, instrumentation and other specialist systems, blue sleeving may also be used as part of a documented cable identification scheme. However, it should not be applied in a way that incorrectly identifies the electrical function of a conductor. Where blue denotes neutral, avoid using it to identify line, protective earth or mixed-function conductor groups.
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. The HSMB16BLUE should not be assumed to provide adhesive sealing or a particular waterproof rating without confirmation from the manufacturer's technical documentation.
