HSMB48BROWN Partex 2:1 heat shrink tubing, 4.8/2.4mm, brown, pack 12m

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.

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.
