Why Choose the Partex HS2127BLUE 2:1 Blue Heat Shrink Tubing?
The Partex HS2127BLUE is a versatile 2:1 blue heat shrink tubing designed to provide electrical insulation, cable identification and mechanical protection for wires and electrical connections. Supplied in blue, this heat shrink sleeving is suitable for professional electrical installations, control panel assembly, cable harness manufacturing and industrial maintenance applications.
Manufactured as part of the Partex heat shrink tubing range, HS2127BLUE provides a practical solution for protecting and organising electrical wiring. When heated appropriately, the tubing contracts around the cable or component, producing a close-fitting protective sleeve that helps reduce exposure to abrasion and everyday handling damage. Its blue finish also supports visual identification of wiring and cable assemblies where this colour is appropriate for the installation.
With a nominal supplied internal diameter of 12.7 mm, a nominal fully recovered diameter of 6.3 mm and a 2:1 shrink ratio, HS2127BLUE is suitable for appropriately sized electrical cables, conductor bundles, cable joints and electrical connections. Supplied in a 50 m pack, it offers a convenient solution for repetitive wiring operations, electrical assembly and industrial production environments.

Reliable Cable Insulation and Protection for Industrial Electrical Installations
Heat shrink tubing provides a practical method of insulating and protecting electrical conductors, cable joints and terminations. The Partex HS2127BLUE uses heat-activated contraction to form a close-fitting sleeve around suitable wiring, helping to improve cable organisation and reduce exposure to abrasion during normal service. Its nominal 12.7 mm supplied diameter makes it useful for cable assemblies requiring a larger initial opening than smaller heat shrink tubing sizes.
The 2:1 shrink ratio allows the tubing to contract from its nominal 12.7 mm supplied diameter towards a 6.3 mm fully recovered diameter. This provides flexibility when covering conductors, cable bundles and components with variations in diameter. The blue colour can assist with cable identification in electrical panels and wiring harnesses. In harmonised UK and European AC wiring systems, blue is commonly used to identify neutral conductors, although colour selection must always comply with the applicable wiring standards and conductor identification scheme.
The 50 m pack is convenient for repeated cutting and installation in electrical workshops, control panel production and industrial maintenance environments. For reliable results, select tubing that can pass over the cable or connection before shrinking and recover sufficiently to grip the finished assembly. Apply heat evenly using an appropriate heat gun and allow the sleeve to cool before handling. Where environmental sealing is required, select a suitable adhesive-lined or sealing product rather than assuming standard heat shrink tubing provides a watertight joint.
