Why Choose the Partex HS212RED 2:1 Heat Shrink Tubing?
The Partex HS212RED is a compact 2:1 heat shrink tubing solution designed for electrical insulation, wire identification, cable protection and professional wiring applications. Supplied in red with a nominal expanded diameter of 1.2 mm and a recovered diameter of 0.6 mm, this heat shrink sleeve is particularly suitable for small-diameter conductors, fine wiring and compact electrical assemblies.
Featuring a 2:1 shrink ratio, the Partex HS212RED reduces to approximately half its original internal diameter when correctly heated, allowing the tubing to form a close-fitting sleeve around suitably sized wires and components. This makes it a practical choice for insulating individual conductors, covering small electrical joints, protecting wiring from light abrasion and providing clear visual identification in control panels and wiring harnesses.
The distinctive red heat shrink tubing provides an easily recognisable finish for cable identification and organised electrical installations. Supplied in a generous 150 metre pack, the HS212RED is particularly convenient for electrical panel builders, electronics technicians, OEM manufacturers and maintenance engineers who require consistent access to small-diameter heat shrink sleeving for repetitive installation and assembly tasks.

Precision Heat Shrink Insulation for Fine Wiring and Electrical Assemblies
The Partex HS212RED 2:1 heat shrink tubing is designed for installations requiring a compact protective sleeve around small electrical conductors. With a nominal diameter of 1.2 mm before shrinking and 0.6 mm after full recovery, it is particularly useful for fine wiring, small terminal connections and electronic assemblies where larger sleeving may be unsuitable.
When heat is applied evenly using a suitable heat gun or controlled heating tool, the tubing contracts around the underlying wire or component. This creates a close-fitting finish that helps protect the covered area from incidental contact, light abrasion and handling damage. The tubing should be selected so that its expanded diameter can pass over the component and its recovered diameter provides an appropriate fit.
The red finish is useful for distinguishing wiring groups, identifying selected conductors and maintaining consistent cable management practices. In control panels and equipment assemblies, colour-coded heat shrink tubing can help technicians recognise wiring arrangements more quickly during installation, inspection and maintenance. Colour identification should always follow the applicable wiring standards and site conventions.
The generous 150 metre supply makes the HS212RED suitable for repetitive production and installation work. Installers can cut individual sleeves to the required length, reducing unnecessary material waste and accommodating a variety of small electrical connections and cable identification tasks.
For installations requiring a specified insulation voltage, flame-retardancy classification, operating temperature range, chemical resistance or adhesive-lined moisture sealing, the relevant manufacturer ratings should be confirmed before use. A standard 2:1 shrink ratio does not by itself establish these performance characteristics.
Typical Applications
