Why Choose the Partex HS2191RED 2:1 Heat Shrink Tubing?
The Partex HS2191RED is a practical and versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, wire identification and professional cable management. Manufactured by Partex, this red heat shrink sleeving provides a convenient solution for protecting insulated conductors, cable assemblies and electrical connections in industrial automation systems, control panels and electrical installations.
Featuring a 2:1 shrink ratio, the tubing contracts to approximately half its original internal diameter when heated appropriately. This allows it to form a close-fitting protective sleeve around compatible cables, wires and electrical components. The distinctive red colour supports visual cable identification, helping engineers and installers distinguish designated wiring groups, circuits and equipment connections within organised electrical installations.
With a supplied internal diameter of 19.1 mm and a nominal recovered diameter of 9.5 mm, the HS2191RED is suitable for a range of larger-diameter cables, wiring assemblies and conductor protection applications. Supplied in a convenient 50 m pack, this red heat shrink tubing offers a practical bulk solution for electrical contractors, control panel builders, OEM manufacturers and industrial maintenance teams.

Reliable Electrical Insulation and Colour-Coded Cable Protection
Heat shrink tubing such as the Partex HS2191RED provides a convenient method of insulating and protecting electrical wiring. When suitable heat is applied, the tubing contracts around the cable or component, creating a close-fitting sleeve that helps protect against abrasion and handling damage. The 2:1 shrink ratio provides flexibility when selecting tubing for compatible cable and conductor sizes. For effective installation, the tubing must be large enough to pass over the application before shrinking while having sufficient recovery to grip the finished assembly.
The red finish makes the HS2191RED particularly useful for colour-coded cable identification and organised electrical installations. Red sleeving can help distinguish selected wiring groups, cable assemblies or equipment connections where the colour is appropriate under the applicable identification scheme. Its 50 m pack supports repeated installation tasks and electrical assembly work, making it a practical choice for industrial automation, control panel manufacturing and electrical maintenance. Cable identification should always follow relevant wiring standards and site requirements rather than relying on colour alone to determine conductor function.
Typical Applications
- Electrical cable insulation and protection.
- Industrial control panel wiring and assembly.
- PLC and automation equipment cable management.
- Red cable identification and colour-coded wiring systems.
- Protection of compatible larger-diameter conductors and insulated connections.
- Cable harness assembly and equipment maintenance.
- OEM machinery wiring and industrial electrical manufacturing.
