Why Choose the Partex HS2191GREY 2:1 Grey Heat Shrink Tubing?
The Partex HS2191GREY is a versatile 2:1 grey heat shrink tubing designed for electrical insulation, cable identification and mechanical protection of wires, cable bundles and electrical connections. Featuring a nominal supplied diameter of 19.1 mm and a nominal recovered diameter of 9.5 mm, this heat shrink sleeving provides a practical solution for protecting larger conductors and cable assemblies in industrial electrical installations.
Part of the Partex heat shrink tubing range, HS2191GREY uses heat-activated contraction to form a close-fitting sleeve around appropriately sized cables and components. The tubing helps protect covered wiring against abrasion and routine handling damage while providing a neat, professional finish. Its grey colour also supports visual identification and cable organisation where this colour is appropriate to the installation's wiring identification scheme.
With a 2:1 nominal shrink ratio, the tubing can contract from its supplied diameter of 19.1 mm towards a recovered diameter of 9.5 mm when heated correctly. Supplied in a convenient 50 m pack, Partex HS2191GREY is suitable for control panel manufacturers, electrical contractors, industrial maintenance engineers and OEM equipment builders requiring cut-to-length protective sleeving.

Reliable Insulation and Protection for Larger Cable Assemblies
The Partex HS2191GREY provides a convenient solution for protecting cables and electrical connections that require a larger sleeve opening. Its nominal 19.1 mm supplied diameter allows the tubing to be positioned over appropriately sized cable bundles, wiring transitions and components before heat is applied. Once heated correctly, the tubing contracts around the assembly to create a close-fitting protective covering.
The 2:1 shrink ratio offers flexibility when selecting tubing for cable assemblies with variations in diameter. The nominal recovered diameter of 9.5 mm allows the tubing to reduce significantly from its original size, helping installers achieve a tidy and consistent finish. Correct sizing is essential: the tubing must fit over the largest part of the assembly before shrinking and recover sufficiently to grip the intended surface.
Its grey finish makes HS2191GREY useful for colour-coded cable management and visual identification where permitted by the relevant wiring standards. In harmonised UK and European three-phase AC wiring systems, grey is commonly used to identify the L3 line conductor. However, the appropriate conductor identification must always be determined by the applicable electrical installation requirements rather than colour alone.
The 50 m pack is particularly convenient for panel-building workshops, electrical assembly operations and maintenance departments that regularly prepare cable sleeving. Installers can cut the required length, position it over the conductor or cable assembly and apply controlled heat using an appropriate heat gun. For applications requiring moisture sealing, a specifically rated adhesive-lined or sealing product should be selected rather than assuming standard heat shrink tubing provides a watertight seal.
