Why Choose the Partex HSMB48BROWN 2:1 Brown Heat Shrink Tubing?

The Partex HSMB48BROWN is a versatile 2:1 brown heat shrink tubing product designed for electrical insulation, wire protection, cable identification and professional cable management. Manufactured by Partex, a specialist in cable marking and identification solutions, this heat shrink tubing provides a practical way to protect electrical conductors and create neat, organised wiring installations in industrial and commercial environments.

Featuring a nominal supplied diameter of 4.8 mm and a fully recovered diameter of approximately 2.4 mm, the HSMB48BROWN is suitable for appropriately sized electrical wires, insulated connections and compact cable assemblies. Its 2:1 shrink ratio allows the tubing to contract to approximately half its original diameter when correctly heated, creating a close-fitting protective sleeve around compatible conductors and components.

Supplied in a convenient 12 m pack with a distinctive brown finish, the Partex HSMB48BROWN is ideal for electrical control panel wiring, industrial automation, electronic equipment and cable harness manufacturing. The brown colour provides a useful visual identification option for designated wiring groups and circuits, helping improve cable organisation and simplify maintenance where the chosen colour identification complies with applicable electrical standards.

Key Advantages

  • 2:1 heat shrink ratio provides a close-fitting protective sleeve around suitable electrical conductors.
  • 4.8 mm nominal supplied diameter suitable for small and medium-sized wires and cable assemblies.
  • 2.4 mm nominal recovered diameter for effective coverage of appropriately sized wiring.
  • Brown colour supports visual conductor identification and organised cable management.
  • 12 m pack length provides convenient material for multiple electrical installation and maintenance tasks.
  • Provides additional electrical insulation and mechanical protection when correctly specified and installed.
  • Helps protect insulated wires and cable connections against abrasion, handling damage and general mechanical wear.
  • Can be cut to the required length for individual wiring, cable identification and protective sleeving applications.

Key Features

  • Partex HSMB heat shrink tubing for professional electrical and cable management applications.
  • 2:1 nominal shrink ratio.
  • 4.8 mm nominal diameter before shrinking.
  • 2.4 mm nominal recovered diameter.
  • Brown tubing colour for visual identification and cable organisation.
  • 12 m supplied pack length.
  • Heat-activated shrinking for a close-fitting protective sleeve.
  • Suitable for electrical wires, cable harnesses and compatible insulated connections.
  • Provides an additional protective layer around appropriately sized electrical conductors.
  • Helps create neat, professional cable assemblies and wiring installations.
  • Suitable for industrial automation, electrical control panels and general wiring maintenance.

Reliable Insulation and Identification for Electrical Wiring

Heat shrink tubing provides a convenient method of protecting electrical conductors, insulated connections and cable assemblies. The Partex HSMB48BROWN features a 2:1 shrink ratio, allowing its nominal diameter to reduce from 4.8 mm to approximately 2.4 mm when heated under appropriate conditions.

The tubing is suitable for a range of electrical wiring applications where a neat, close-fitting protective sleeve is required. Its brown finish can help distinguish designated conductors or wiring groups within cable assemblies. In UK and harmonised European electrical installations, brown is commonly used to identify a line conductor, although the correct identification must always be determined by the applicable wiring standard and installation requirements.

When correctly selected and installed, heat shrink tubing helps provide supplementary insulation and protection against mechanical wear. It can also improve the appearance of wiring assemblies by covering suitable insulated connections and exposed sections of cable sleeving. The tubing does not replace correctly rated primary conductor insulation or other required electrical safety measures.

For effective installation, select tubing that passes over the largest part of the wire or component before shrinking and has a recovered diameter small enough to grip the intended surface. Cut the tubing to the required length, position it correctly and apply controlled, even heat using a suitable heat gun. Always follow the manufacturer's recommended installation conditions and avoid overheating adjacent components.

Typical Applications

  • Electrical insulation and protective sleeving for appropriately sized wires.
  • Industrial control panel wiring and conductor identification.
  • Electrical line conductor identification where permitted by applicable standards.
  • Electronic equipment assembly and maintenance.
  • Protection of suitable soldered wire joints and insulated connections.
  • Cable harnesses and wiring looms.
  • Industrial automation and instrumentation wiring.
  • Colour-coded cable organisation and identification.
  • Electrical machinery and equipment wiring.
  • Electrical repair, refurbishment and maintenance work.

Frequently Asked Questions

What is the Partex HSMB48BROWN used for?

The Partex HSMB48BROWN is a brown 2:1 heat shrink tubing product used for electrical insulation, wire protection, conductor identification and professional cable management. It is suitable for appropriately sized electrical conductors, control wiring and cable assemblies.

What does the 2:1 shrink ratio mean?

A 2:1 shrink ratio means the tubing can reduce to approximately half its original diameter when correctly heated. The Partex HSMB48BROWN has a nominal supplied diameter of 4.8 mm and a fully recovered diameter of approximately 2.4 mm.

What size and pack length is the Partex HSMB48BROWN?

The tubing has a 4.8 mm nominal supplied diameter, a 2.4 mm nominal recovered diameter and is supplied in a 12 m pack. It can be cut to suitable lengths for individual wiring and cable protection applications.

What are the benefits of brown heat shrink tubing?

The brown colour provides a useful visual identification option for electrical conductors and cable assemblies. Brown is commonly associated with line conductor identification in UK and harmonised European wiring systems, but the selected identification must always comply with applicable electrical installation standards.

How is the Partex HSMB48BROWN heat shrink tubing installed?

Cut the tubing to the required length, position it over the wire or insulated connection and apply controlled, even heat using a suitable heat gun. The tubing contracts around the underlying surface as it heats. Always follow the manufacturer's recommended installation conditions and ensure the selected tubing is suitable for the intended electrical and environmental conditions.

Trusted Cable Identification and Protection Solutions

Partex provides professional cable identification and management solutions for electrical installations and industrial applications. The HSMB48BROWN 2:1 brown heat shrink tubing offers a practical solution for insulating, protecting and identifying electrical wires, with a convenient 12 m pack suitable for professional control panel wiring, cable assembly and maintenance tasks.
