Why Choose the Partex HSMB64EARTH(GRN/YEL) 2:1 Green/Yellow Heat Shrink Tubing?

The Partex HSMB64EARTH(GRN/YEL) is a professional 2:1 green/yellow heat shrink tubing product designed for protective earth conductor identification, electrical insulation and cable protection. Manufactured by Partex, a specialist in cable marking and identification solutions, this dual-colour heat shrink tubing provides a practical way to identify protective earth conductors while creating neat, organised and professionally finished electrical installations.

Featuring a nominal supplied diameter of 6.4 mm and a nominal recovered diameter of 3.2 mm, the HSMB64EARTH(GRN/YEL) is suitable for appropriately sized protective earth conductors, insulated electrical connections and 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 identification and protective sleeve.

Supplied in a convenient 12 m pack with distinctive green/yellow colouring, the Partex HSMB64EARTH(GRN/YEL) is ideal for protective earth identification in electrical control panels, industrial machinery, distribution equipment and automation systems. The green/yellow colour combination is recognised for protective earth identification under UK and harmonised European electrical wiring standards, helping electricians and maintenance engineers identify protective conductors clearly and consistently.

Key Advantages

  • 2:1 heat shrink ratio provides a close-fitting protective sleeve around suitable electrical conductors.
  • 6.4 mm nominal supplied diameter suitable for appropriately sized protective earth conductors and cable assemblies.
  • 3.2 mm nominal recovered diameter for effective coverage of compatible wiring.
  • Green/yellow dual-colour finish provides clear identification of protective earth conductors.
  • 12 m pack length provides convenient material for multiple electrical installation and maintenance tasks.
  • Supports consistent protective earth (PE) conductor identification in electrical control panels and industrial equipment.
  • Provides additional electrical insulation and mechanical protection when correctly specified and installed.
  • Helps protect conductor insulation against abrasion, handling damage and general mechanical wear.
  • Can be cut to the required length for individual conductor identification and protective sleeving applications.

Key Features

  • Partex HSMB heat shrink tubing for professional electrical identification and cable management.
  • 2:1 nominal shrink ratio.
  • 6.4 mm nominal diameter before shrinking.
  • 3.2 mm nominal recovered diameter.
  • Green/yellow dual-colour tubing for protective earth conductor identification.
  • 12 m supplied pack length.
  • Heat-activated shrinking for a close-fitting identification sleeve.
  • Suitable for protective earth conductors, cable assemblies and compatible insulated connections.
  • Helps provide consistent conductor identification within electrical control panels and distribution equipment.
  • Provides an additional protective layer around appropriately sized electrical conductors.
  • Suitable for industrial automation, electrical machinery and protective bonding applications.

Reliable Protective Earth Identification and Cable Protection

Correct identification of protective earth conductors is an important part of electrical installation safety, inspection and maintenance. The Partex HSMB64EARTH(GRN/YEL) combines the recognised green/yellow protective earth colour combination with the practical benefits of heat shrink tubing, helping electricians and maintenance engineers distinguish protective conductors from other wiring within electrical assemblies.

The tubing features a 2:1 shrink ratio, allowing its nominal diameter to reduce from 6.4 mm to approximately 3.2 mm when heated under appropriate conditions. This shrinking action enables the tubing to conform closely to the underlying conductor insulation, providing a neat identification sleeve with supplementary protection against abrasion and handling.

The green/yellow colour combination is reserved for protective conductor identification under commonly applied UK and European electrical wiring standards. It should therefore be used only for conductors serving the appropriate protective function. The tubing provides identification and supplementary protection but does not itself establish an electrical earth connection or replace the required conductor insulation, protective bonding, continuity testing or other 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 applicable electrical installation standards.

Typical Applications

  • Protective earth (PE) conductor identification in electrical installations.
  • Industrial control panel wiring and earth conductor marking.
  • Electrical distribution boards and switchgear assemblies.
  • Protective bonding conductor identification in industrial machinery.
  • Automation equipment and electrical control systems.
  • Electrical cabinet assembly, installation and maintenance.
  • Protective earth identification within cable harnesses and wiring looms.
  • Electrical equipment manufacturing and refurbishment.
  • Identification of appropriately sized protective conductors at electrical terminals.
  • Industrial electrical repair and maintenance work.

Frequently Asked Questions

What is the Partex HSMB64EARTH(GRN/YEL) used for?

The Partex HSMB64EARTH(GRN/YEL) is a green/yellow 2:1 heat shrink tubing product used primarily for protective earth conductor identification, supplementary electrical insulation and cable protection in industrial and commercial electrical installations.

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 HSMB64EARTH(GRN/YEL) has a nominal supplied diameter of 6.4 mm and a nominal fully recovered diameter of 3.2 mm.

What size and pack length is the Partex HSMB64EARTH(GRN/YEL)?

The tubing has a 6.4 mm nominal supplied diameter, a 3.2 mm nominal recovered diameter and is supplied in a 12 m pack. It can be cut to suitable lengths for individual protective earth identification and cable protection applications.

Why is this heat shrink tubing green and yellow?

The green/yellow colour combination is used to identify protective earth conductors in accordance with commonly applied UK and European electrical wiring standards. This helps distinguish protective conductors from line and neutral conductors, supporting clear identification during installation, inspection and maintenance.

How is the Partex HSMB64EARTH(GRN/YEL) heat shrink tubing installed?

Cut the tubing to the required length, position it over the appropriate protective earth conductor 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 conductor identification complies with applicable electrical standards.

Trusted Cable Identification and Protection Solutions

Partex provides professional cable identification and management solutions for electrical installations and industrial applications. The HSMB64EARTH(GRN/YEL) 2:1 green/yellow heat shrink tubing offers a practical solution for identifying and protecting appropriately sized protective earth conductors, with a convenient 12 m pack suitable for electrical control panel assembly, machinery wiring and maintenance applications.
