Why Choose the Partex HS212BLUE 2:1 Blue Heat Shrink Tubing?
The Partex HS212BLUE is a versatile 2:1 blue heat shrink tubing designed for insulating, protecting and identifying small electrical wires, cable connections and electronic components. Featuring a 1.2 mm nominal supplied diameter and a 0.6 mm nominal fully recovered diameter, this compact heat shrink sleeve provides a practical solution for applications requiring a neat, close-fitting protective covering around small conductors and wiring assemblies.
With a 2:1 shrink ratio, the HS212BLUE is designed to reduce to approximately half its original diameter when heated under suitable conditions. This allows the tubing to be positioned over a compatible wire or connection before shrinking to form a closely fitting sleeve. Its distinctive blue finish is particularly useful for colour-coded wiring arrangements, helping installers distinguish selected cable groups, circuits or equipment connections according to their own identification systems.
Supplied in a generous 150 m pack, the Partex HS212BLUE is suitable for electrical contractors, electronics manufacturers, control panel builders, maintenance engineers and OEM equipment manufacturers. Its small diameter, heat-activated recovery and cut-to-length flexibility make it an effective choice for precision wiring, cable identification and professional electrical assembly work.

Reliable 2:1 Heat Shrink Protection and Cable Identification for Electrical Installations
Effective electrical insulation and cable identification help maintain organised, accessible and dependable wiring assemblies. The Partex HS212BLUE provides a convenient method of applying a closely fitting sleeve to compatible small conductors, wire joints and electronic connections. Once positioned and exposed to suitable heat, the tubing reduces in diameter around the underlying component, helping create a neat protective covering without requiring separate fastening accessories.
The compact 1.2 mm to 0.6 mm nominal diameter range is particularly useful for precision wiring applications involving small conductors and electronic equipment. The tubing should be selected so that its supplied diameter is large enough to pass over the intended component, while its recovered diameter is sufficiently small to achieve the required fit. The blue finish also allows installers to implement colour-coded cable identification arrangements, supporting easier visual recognition of selected wiring groups during inspection, commissioning and maintenance.
For dependable results, the tubing should be cut cleanly, positioned over the intended wire or connection and heated evenly using appropriate equipment. Excessive or uneven heating should be avoided to prevent damage to the tubing or underlying cable insulation. The HS212BLUE should not be assumed to be adhesive-lined, waterproof, flame-retardant or suitable for a particular operating voltage or temperature without confirmation of the relevant manufacturer specification. Blue colour-coding should also follow the applicable installation requirements and must not be treated as automatic confirmation of a conductor's electrical function.
Typical Applications
- Insulation of small electrical wires and conductor sections.
- Colour-coded identification of compatible wiring groups.
