Why Choose the Partex HSMB12BLUE Heat Shrink Tubing?
The Partex HSMB12BLUE is a compact blue 2:1 heat shrink tubing designed for electrical insulation, wire identification and protective sleeving in industrial and commercial electrical installations. Supplied in a convenient 20 m pack, this small-diameter tubing provides a practical solution for protecting fine wires, small electrical connections and wiring assemblies.
Featuring a nominal supplied internal diameter of 1.2 mm and a nominal recovered internal diameter of 0.6 mm, the tubing contracts when suitable heat is applied to form a close-fitting protective sleeve around compatible conductors and components. Its 2:1 shrink ratio allows the diameter to reduce to approximately half its original size, making it particularly suitable for precision wiring and small cable identification applications.
The distinctive blue colour supports visual wire identification and organised cable management. As part of the Partex heat shrink tubing range, the HSMB12BLUE is suitable for electrical contractors, electronics technicians, panel builders and maintenance engineers requiring compact protective sleeving for professional wiring applications.
Key Advantages
- 2:1 heat shrink ratio provides controlled diameter reduction when heated.
- 1.2 mm nominal supplied diameter suitable for fine wires and small electrical components.

- 20 m pack length provides material for multiple small wiring applications.
- Provides additional electrical insulation and mechanical protection for compatible conductors.
- Suitable for electronics wiring, control panels, wiring harnesses and electrical maintenance.
Key Features
- Partex HSMB12BLUE heat shrink tubing.
- 2:1 shrink ratio for heat-activated diameter reduction.
- 1.2 mm nominal supplied internal diameter.
- 0.6 mm nominal recovered internal diameter.
- Blue colour for wire identification and organised electrical installations.
- 20 m supplied length.

- Heat-activated protective sleeving for electrical insulation and mechanical protection.
- Can be cut to the required length for individual wiring applications.
Reliable Insulation and Identification for Fine Electrical Wires
Small-diameter heat shrink tubing provides a convenient method of insulating, identifying and protecting fine electrical conductors. When suitable heat is applied, the tubing contracts around the underlying wire or component, forming a close-fitting sleeve that helps reduce exposure to abrasion and general mechanical wear.
The Partex HSMB12BLUE is particularly useful for wiring applications requiring a small initial opening. Its 1.2 mm nominal supplied diameter accommodates suitably sized fine wires, while the 2:1 shrink ratio allows the tubing to recover towards a nominal internal diameter of 0.6 mm.
The blue finish provides an additional visual identification method for organised electrical installations. In systems following applicable UK and European wiring conventions, blue is commonly associated with neutral conductors, although colour identification must always comply with the requirements of the particular installation.
Typical Applications
- Fine electrical wire insulation and protective sleeving.
- Small electrical connections and wire joints.
- Electronics wiring and component assemblies.
- Industrial control panels and automation equipment.
- Blue colour-coded wire and conductor identification.
- Small wiring harnesses and cable assemblies.
- Electrical maintenance, workshop repairs and precision wiring applications.
