Why Choose the Partex HSMB191GREY 2:1 Heat Shrink Tubing?
The Partex HSMB191GREY is a practical 2:1 grey heat shrink tubing designed for electrical insulation, cable protection and colour-coded wire identification in industrial, commercial and electrical engineering applications. With a nominal supplied internal diameter of 19.1 mm and a nominal fully recovered internal diameter of 9.5 mm, this heat shrink sleeving is suitable for appropriately sized cables, wiring harnesses, electrical connections and cable terminations.
As part of the Partex HSMB heat shrink tubing range, the HSMB191GREY offers a convenient solution for protecting and organising electrical wiring. Its 2:1 shrink ratio allows the tubing to contract around suitable cables and components when controlled heat is applied, creating a close-fitting protective sleeve. This helps provide additional insulation coverage, reduce exposure to abrasion and everyday mechanical wear, and deliver a tidy, professional finish to electrical installations.
Supplied in a convenient 5 m pack, the Partex HSMB191GREY is suitable for electrical contractors, control panel manufacturers, industrial maintenance engineers and equipment builders requiring dependable larger-diameter heat shrink sleeving. Its distinctive grey finish supports visual cable identification and organised wiring systems, making it particularly useful in electrical cabinets, industrial automation equipment, cable harness production and maintenance applications.

Reliable Cable Insulation and Grey Colour-Coded Wire Identification
The Partex HSMB191GREY heat shrink tubing provides a practical method of insulating and protecting electrical cables, cable joints and wiring assemblies. When controlled heat is applied, the tubing contracts around the underlying cable or component, helping create a close-fitting protective sleeve. Its larger nominal supplied diameter makes it useful for covering appropriately sized cable insulation, connection points and wiring harness sections where smaller heat shrink tubing would be unsuitable.
Its 2:1 shrink ratio means that the nominal internal diameter can reduce from 19.1 mm to approximately 9.5 mm when fully recovered. For effective installation, the tubing must be large enough to pass over the widest part of the assembly before heating, while the recovered diameter should be sufficiently small to grip the intended section. The 5 m pack length can be cut into individual sleeves, helping installers use the appropriate amount of material for cable terminations, conductor protection and wiring harness production.
The grey finish is useful in industrial control cabinets, equipment assemblies and cable management systems where colour coding supports installation, inspection and maintenance. Grey is also associated with a line conductor in certain UK and European wiring conventions, although its use on heat shrink sleeving must follow the applicable identification requirements and installation documentation. This general-purpose heat shrink tubing should not be relied upon to create a waterproof seal; applications requiring moisture sealing should use a suitably specified adhesive-lined product.
Typical Applications
- Electrical insulation of appropriately sized cables and conductors.
- Protection of cable joints and electrical connections.
- Grey colour-coded cable and conductor identification.
- Industrial control panel wiring and cable management.
- Electrical cabinet manufacturing and assembly.
- Industrial automation and machine control systems.
- Protective sleeving for wiring harnesses and cable assemblies.
- Maintenance and repair of electrical equipment wiring.
- Insulation of suitable cable terminations and connection points.
- OEM machinery manufacturing and industrial engineering projects.
