HSMB12RED Partex 2:1 heat shrink tubing, 1.2/0.6mm, red, pack 20m

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.

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.
