Why Choose the Partex HSMB64BLACK 2:1 Black Heat Shrink Tubing?

The Partex HSMB64BLACK is a versatile and reliable black heat shrink tubing designed to provide electrical insulation, cable protection and a neat, professional finish to wiring installations. Featuring a 2:1 shrink ratio, this tubing contracts to approximately half its original diameter when heated, allowing it to fit securely around suitably sized cables, wires and electrical connections.

As part of the Partex heat shrink tubing range, HSMB64BLACK is suitable for cable insulation, wire protection, cable identification systems and general electrical assembly work. Its black finish provides a uniform appearance for wiring installations while helping protect covered components against abrasion and routine handling damage.

With a nominal supplied internal diameter of 6.4 mm, a fully recovered internal diameter of approximately 3.2 mm and a 12 m pack length, this black heat shrink tubing offers a practical solution for electrical contractors, panel builders, maintenance engineers and industrial automation specialists. Its cut-to-length format makes it suitable for cable harnesses, insulated connections and electrical control panel assemblies.

Key Advantages

  • 2:1 heat shrink ratio provides a close-fitting protective sleeve around suitably sized cables and components.
  • 6.4 mm supplied diameter reduces to approximately 3.2 mm after full recovery.
  • Black finish provides a neat and consistent appearance in electrical installations.
  • Provides an additional layer of electrical insulation and mechanical protection when correctly selected and installed.
  • 12 m pack length allows tubing to be cut to suit individual installation requirements.
  • Suitable for professional cable management, electrical wiring assemblies and industrial control panels.
  • Helps protect insulated connections and cable sections against abrasion and handling damage.

  • Black colour for a consistent wiring finish.
  • 12 m pack length for flexible cutting and installation.
  • Heat-activated shrinking provides a close-fitting protective covering.
  • Suitable for cable insulation, wire protection and electrical assembly applications.
  • Can be cut into shorter sections for individual cable and connection requirements.
  • Designed for use in electrical installation, maintenance and cable harness assembly work.

Reliable Cable Insulation and Protection for Electrical Installations

Heat shrink tubing provides a practical method of insulating and protecting electrical wiring. When suitable heat is applied, the tubing contracts around the cable or component, creating a close-fitting sleeve that helps protect against abrasion, handling damage and accidental contact with covered conductive parts. The Partex HSMB64BLACK uses a 2:1 shrink ratio, allowing its nominal internal diameter to reduce from 6.4 mm to 3.2 mm when fully recovered.

The black finish is particularly useful for electrical assemblies requiring a consistent and professional appearance. The tubing can be installed over appropriately sized insulated wire sections, cable joints and electrical components to provide an additional protective covering. For dependable results, the tubing should be selected according to the dimensions of the cable or component and installed using appropriate controlled heating equipment. It should not be treated as a substitute for a correctly rated connector, enclosure or primary insulation system unless the complete installation has been suitably assessed.

Typical Applications

  • Electrical cable insulation and protection.
  • Insulation of suitably sized wire joints and electrical connections.
  • Industrial control panel wiring and cable management.
  • Low-voltage electrical wiring assemblies.
  • Protection of cable harnesses and wire bundles.
  • Automation equipment and control system installations.
  • Electrical equipment maintenance and repairs.
  • OEM cable harnesses and wiring assemblies.
  • Protective sleeving for cables exposed to routine handling and abrasion.
  • General electrical installation and workshop applications.

Frequently Asked Questions

What is the Partex HSMB64BLACK heat shrink tubing used for?

The Partex HSMB64BLACK is used for electrical insulation, cable protection and wiring assembly applications. It provides a close-fitting protective sleeve around suitably sized wires, cable joints and electrical components.

What does the 2:1 shrink ratio mean?

A 2:1 shrink ratio means that the tubing can reduce to approximately half its original internal diameter when fully recovered. The HSMB64BLACK has a nominal supplied diameter of 6.4 mm and a nominal recovered diameter of 3.2 mm.

How much tubing is supplied in one pack?

Each pack contains 12 m of black heat shrink tubing, which can be cut into shorter sections to suit individual wiring and cable protection requirements.

Can Partex HSMB64BLACK be used for cable joints and electrical connections?

Yes. The tubing can provide additional insulation and mechanical protection around appropriately sized cable joints and electrical connections. The connection must be correctly made, and the tubing must be suitable for the electrical and environmental conditions of the installation.

How is Partex HSMB64BLACK installed?

Cut the tubing to the required length, position it over a suitably sized wire or component and apply controlled heat using an appropriate heat gun. The tubing contracts around the component to provide a close-fitting protective sleeve. Avoid overheating and ensure the installation is suitable for the tubing's specified operating conditions.
