Why Choose the Partex HSMB48BLUE Blue Heat Shrink Tubing?
The Partex HSMB48BLUE is a versatile blue 2:1 heat shrink tubing designed for electrical insulation, cable identification and protection of wires and connections. Supplied in a convenient 12 m pack, this heat shrink sleeve has a nominal diameter of 4.8 mm before shrinking and 2.4 mm after shrinking, making it suitable for a wide range of electrical installation, maintenance and cable management applications.
As part of the Partex heat shrink tubing range, HSMB48BLUE provides a practical solution for protecting and organising electrical wiring. When heated correctly, the tubing contracts around cables, terminals and connections to provide a close-fitting insulating sleeve. Its blue colour also supports colour-coded cable identification and organised wiring systems.
With its 2:1 shrink ratio, flexible sleeving format and convenient 12 m pack length, the Partex HSMB48BLUE is ideal for electricians, control panel builders, maintenance engineers and industrial automation professionals requiring dependable cable insulation and identification.

Reliable Electrical Insulation and Cable Identification
Heat shrink tubing is widely used in electrical installations to insulate conductors, protect cable connections and provide a tidy finish to wiring assemblies. The Partex HSMB48BLUE works by contracting when suitable heat is applied, allowing the tubing to conform closely to the underlying cable or component.
The 2:1 shrink ratio means that the tubing can reduce from its nominal 4.8 mm diameter to approximately 2.4 mm under appropriate shrinking conditions. For effective installation, select tubing that fits over the largest part of the connection before shrinking and contracts sufficiently around the smallest section. The blue finish makes it particularly useful for organised electrical wiring, cable identification and colour-coded maintenance systems.
Typical Applications
- Electrical wire insulation and cable protection.
- Colour-coded cable identification and wiring organisation.
- Control panel wiring and electrical cabinet assemblies.
- Protection of soldered wire joints and compatible terminals.
- Industrial automation and machinery wiring.
- Electrical maintenance, repairs and cable assembly work.
- Low-voltage electrical installations where the tubing's insulation rating is appropriate.
