Why Choose the Partex HSMB12RED 2:1 Heat Shrink Tubing?

The Partex HSMB12RED is a high-quality 2:1 red heat shrink tubing designed for electrical insulation, wire identification and cable protection in industrial, commercial and electrical engineering applications. With a nominal supplied internal diameter of 1.2 mm and a nominal recovered internal diameter of 0.6 mm, this compact heat shrink sleeving is particularly suitable for fine wires, small electrical connections and precision wiring assemblies.

As part of the Partex HSMB heat shrink tubing range, the HSMB12RED provides a convenient solution for insulating and organising electrical conductors. Its 2:1 shrink ratio allows the tubing to contract around wires and components when heated, creating a close-fitting protective sleeve that helps reduce abrasion, improve insulation coverage and deliver a neat, professional finish.

Supplied in a convenient 20 m mini-box, the Partex HSMB12RED is ideal for control panel builders, electrical contractors, electronics technicians and industrial maintenance engineers requiring dependable small-diameter heat shrink sleeving. Its distinctive red colour supports visual wire identification and colour-coded electrical installations, while the flexible construction makes it suitable for detailed wiring and assembly work.

Key Advantages

  • High-quality 2:1 heat shrink tubing for electrical insulation and wire protection.
  • 1.2 mm nominal supplied diameter reducing to approximately 0.6 mm after full recovery.
  • 20 m mini-box provides convenient dispensing, storage and handling.
  • Small-diameter construction ideal for fine wires and compact electrical connections.
  • Red colour supports visual wire identification and colour-coded cable management.
  • Flexible heat-shrinkable polyolefin construction conforms closely around suitable wires and components.
  • Helps protect electrical conductors against abrasion and everyday mechanical wear.
  • Provides a neat, professional finish for electrical wiring and cable assemblies.
  • Can be cut to the required length to minimise material waste.
  • Suitable for industrial automation, control panel wiring and electronics assembly.

Key Features

  • Partex HSMB mini-box heat shrink tubing for professional electrical applications.
  • 2:1 nominal shrink ratio for close-fitting wire insulation.
  • 1.2 mm nominal internal diameter before shrinking.
  • 0.6 mm nominal recovered internal diameter.
  • Red sleeving for electrical insulation and visual identification.
  • 20 m pack length suitable for repeated installation and maintenance tasks.
  • Cross-linked polyolefin construction for flexible electrical insulation.
  • Standard-wall heat shrink tubing for general-purpose cable protection.
  • Suitable for fine conductors, small wire joints and compact wiring assemblies.
  • Helps reduce abrasion and mechanical wear on covered wires.
  • Heat-activated recovery using suitable hot-air equipment.
  • Can be cut into customised lengths before installation.

Precision Insulation and Red Colour-Coded Wire Identification

The Partex HSMB12RED heat shrink tubing provides an effective method of insulating and protecting small electrical conductors, fine wires and compact cable assemblies. When exposed to controlled heat, the tubing contracts around the underlying wire or component, creating a close-fitting protective covering that helps reduce exposure to abrasion and mechanical damage.

Its 2:1 shrink ratio makes it particularly useful for covering small-diameter conductors where a controlled reduction in sleeve diameter is required. The tubing can be cut to the desired length before installation, allowing technicians and engineers to produce neat, consistent protective coverings for electrical connections and wiring assemblies. The 20 m mini-box is convenient for workshops, production benches and maintenance teams that regularly use small sections of heat shrink sleeving.

The red finish is especially useful in control cabinets, electronics assemblies and industrial wiring systems where colour coding helps technicians distinguish between conductors or circuit groups. Red sleeving may be used for identification according to an installation's wiring convention, but colour alone should not be treated as confirmation of a conductor's electrical function. As standard non-adhesive heat shrink tubing, the HSMB12RED is intended for insulation and mechanical protection rather than waterproof sealing.

Typical Applications

  • Electrical insulation of fine wires and small conductors.
  • Protection of compact wire joints and electrical connections.
  • Red colour-coded wire and cable identification.
  • Industrial control panel wiring and cable management.
  • Electronics assembly and low-voltage wiring applications.
  • Industrial automation and machine control wiring.
  • Electrical equipment manufacturing and assembly.
  • Maintenance and repair of small electrical cable assemblies.
  • Protective sleeving for compact wiring harnesses.
  • OEM machinery manufacturing and industrial engineering projects.

Frequently Asked Questions

What is the Partex HSMB12RED heat shrink tubing used for?

The Partex HSMB12RED is used for electrical insulation, wire protection and red colour-coded cable identification in applications involving fine conductors, small electrical connections and compact wiring assemblies.

What is the shrink ratio of the Partex HSMB12RED?

The tubing has a 2:1 shrink ratio, meaning its nominal internal diameter reduces from 1.2 mm to approximately 0.6 mm when fully recovered.

How much heat shrink tubing is supplied in one pack?

The Partex HSMB12RED is supplied in a 20 m mini-box, allowing installers to dispense and cut the tubing into individual lengths for electrical insulation, wire protection and identification applications.

What types of wires can the Partex HSMB12RED protect?

The tubing is suitable for fine wires and small electrical components that fit within its 1.2 mm supplied internal diameter and can be securely covered by its nominal 0.6 mm recovered internal diameter. Select the tubing according to the dimensions of the wire or component, allowing sufficient recovery for a secure fit.

How is the Partex HSMB12RED installed?

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