HSMB64BROWN Partex 2:1 heat shrink tubing, 6.4/3.2mm, brown, pack 12m

Why Choose the Partex HSMB64BROWN 2:1 Heat Shrink Tubing?

The Partex HSMB64BROWN is a versatile 2:1 brown heat shrink tubing designed for electrical insulation, cable identification and wire protection in industrial, commercial and electrical engineering applications. With a nominal supplied internal diameter of 6.4 mm and a nominal fully recovered internal diameter of 3.2 mm, this heat shrink sleeving is suitable for appropriately sized electrical conductors, cable joints and wiring assemblies.

As part of the Partex HSMB mini-box heat shrink tubing range, the HSMB64BROWN provides a convenient way to protect and organise electrical wiring. Its 2:1 shrink ratio allows the tubing to contract around wires and components when heated, creating a close-fitting protective covering that helps reduce abrasion, improve insulation coverage and provide a neat, professional finish. The brown colour also supports consistent identification in colour-coded electrical systems.

Supplied in a convenient 12 m pack, the Partex HSMB64BROWN is ideal for electrical contractors, control panel builders, industrial maintenance engineers and equipment manufacturers requiring dependable heat shrink sleeving. Its combination of practical dimensions, flexible construction and distinctive brown finish makes it a useful choice for electrical cabinet assembly, machinery wiring, cable harness production and routine maintenance work.

Reliable Cable Insulation and Brown Conductor Identification

The Partex HSMB64BROWN heat shrink tubing provides a practical method of protecting electrical conductors, cable joints and wiring assemblies. When controlled heat is applied, the tubing contracts around the underlying wire or component, helping create a close-fitting protective sleeve. This makes it useful for covering suitable cable terminations, providing additional insulation and reducing exposure to abrasion during normal handling and operation.

Its 2:1 shrink ratio means that the nominal internal diameter can reduce from 6.4 mm to approximately 3.2 mm when fully recovered. To achieve a secure fit, the tubing should be large enough to slide over the widest part of the assembly before heating, while its recovered diameter should be smaller than the section it needs to grip. Installers can cut the 12 m length into sections appropriate for individual connections, allowing efficient use during panel building, cable preparation and maintenance.

The brown finish is particularly useful in electrical installations where conductor colours help technicians identify circuits and wiring functions. Brown is commonly associated with line conductors under relevant UK and European wiring conventions, although the actual purpose of each conductor must always be confirmed against the applicable standard 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 wires and conductors.
• Protection of cable joints and electrical connections.
• Brown colour-coded conductor and cable identification.
• Industrial control panel wiring and cable management.
• Electrical cabinet manufacturing and assembly.
• Industrial automation and machine control systems.
• Protective sleeving for cable harnesses and wire assemblies.
• Maintenance and repair of electrical equipment wiring.
• Insulation of suitable cable terminations and connection points.
• OEM machinery manufacturing and industrial engineering projects.
