Why Choose the Partex HSMB191RED 2:1 Heat Shrink Tubing?

The Partex HSMB191RED is a versatile 2:1 red heat shrink tubing designed for electrical insulation, cable protection and colour-coded conductor 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 electrical cables, wiring harnesses, cable terminations and connection assemblies.

As part of the Partex HSMB heat shrink tubing range, the HSMB191RED provides a convenient method of 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 mechanical wear, and deliver a neat, professional finish to electrical installations.

Supplied in a convenient 5 m pack, the Partex HSMB191RED is ideal for electrical contractors, control panel manufacturers, industrial maintenance engineers and equipment builders requiring dependable larger-diameter heat shrink sleeving. Its distinctive red finish supports visual cable identification and organised wiring systems, making it particularly useful in industrial automation equipment, electrical cabinets, wiring harness production and routine maintenance applications.

Key Advantages

  • Professional 2:1 red heat shrink tubing for electrical insulation and cable protection.
  • 19.1 mm nominal supplied diameter reducing to approximately 9.5 mm after full recovery.

Reliable Cable Insulation and Red Colour-Coded Wire Identification

The Partex HSMB191RED 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 particularly 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 its 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 red finish is useful in industrial control cabinets, electrical equipment assemblies and cable management systems where colour coding supports installation, inspection and maintenance. Red sleeving may be used to distinguish selected circuits, conductors or wiring groups within a documented identification scheme, including certain DC wiring applications where appropriate. However, red colour alone must not be treated as confirmation of polarity or conductor function. 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.
  • Red 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.
  • Identification of selected DC conductors where the wiring convention permits.
  • Maintenance and repair of electrical equipment wiring.
  • OEM machinery manufacturing and industrial engineering projects.

Frequently Asked Questions

What is the Partex HSMB191RED heat shrink tubing used for?

The Partex HSMB191RED is used for electrical insulation, cable protection and red colour-coded wire identification. It is suitable for appropriately sized cables, cable terminations, electrical connections and wiring assemblies in control panels, industrial machinery and electrical equipment.

What is the shrink ratio of the Partex HSMB191RED?

The tubing has a 2:1 shrink ratio. Its nominal internal diameter is 19.1 mm before shrinking and approximately 9.5 mm after full recovery. The actual fit depends on the dimensions of the underlying cable or component.

How much heat shrink tubing is supplied in one pack?

Each pack of Partex HSMB191RED contains 5 m of red heat shrink tubing. The tubing can be cut into individual lengths to suit different electrical insulation, identification and cable protection tasks.

Can red Partex heat shrink tubing be used for positive conductor identification?

Yes. Red heat shrink tubing may be used to identify positive conductors in certain DC electrical systems where this matches the applicable wiring convention. However, red sleeving does not automatically indicate positive polarity, and conductor functions must always be confirmed against the relevant electrical standards and installation documentation.

How do you install the Partex HSMB191RED heat shrink tubing?

Cut the tubing to the required length, slide it over the cable or component and apply controlled heat using a suitable hot-air heat gun. Heat evenly until the tubing contracts around the surface. Follow the manufacturer's installation instructions and avoid overheating the tubing, underlying cable insulation or nearby components.

Trusted by Electrical and Industrial Professionals Worldwide

Partex heat shrink tubing provides a practical solution for electrical insulation, cable identification and industrial maintenance applications.
