Why Choose the Partex HSMB12GREY 2:1 Heat Shrink Tubing?
The Partex HSMB12GREY is a compact 2:1 grey heat shrink tubing designed for electrical insulation, wire identification and cable protection in industrial, commercial and electrical engineering applications. With a nominal supplied internal diameter of 1.2 mm and a nominal recovered diameter of 0.6 mm, this small-diameter sleeving is particularly suitable for fine wires, small electrical connections and precision wiring assemblies.
As part of the Partex heat shrink tubing range, the HSMB12GREY provides a practical solution for protecting and organising electrical conductors. Its 2:1 shrink ratio allows the tubing to contract around the underlying wire or component when heated, creating a close-fitting protective sleeve that helps reduce abrasion, improve insulation coverage and provide a neat, professional finish.
Supplied in a convenient 20 m pack, the Partex HSMB12GREY is ideal for control panel builders, electrical contractors, electronics technicians and industrial maintenance engineers requiring reliable small-diameter heat shrink sleeving. Its grey colour supports visual cable identification and organised wiring installations, while the flexible construction makes it suitable for detailed electrical assembly and maintenance work.

Reliable Insulation for Fine Wires and Electrical Connections
The Partex HSMB12GREY heat shrink tubing provides an effective method of insulating and protecting small electrical conductors, fine wires and compact cable assemblies. When heated using suitable equipment, the tubing contracts around the underlying wire or component, creating a close-fitting protective covering that helps reduce exposure to abrasion and mechanical damage.
Its 2:1 shrink ratio makes it particularly useful for covering small-diameter conductors where a controlled reduction in sleeve diameter is required. The tubing can be cut to the desired length before installation, allowing technicians and engineers to produce neat, consistent protective coverings for electrical connections and wiring assemblies.
The grey finish is useful in industrial control cabinets, electronic equipment and cable identification systems where organised wiring improves inspection and maintenance. Its compact dimensions make the HSMB12GREY suitable for detailed electrical assembly work where larger heat shrink tubing would be impractical. As general-purpose heat shrink sleeving, it should not be assumed to provide a waterproof seal without an appropriate sealing system.
Typical Applications
- Electrical insulation of fine wires and small conductors.
- Protection of compact wire joints and electrical connections.
- Industrial control panel wiring and cable management.
- Grey colour-coded wire and cable identification.
- Electronics assembly and low-voltage wiring applications.
- Industrial automation and machine control wiring.
- Electrical equipment manufacturing and assembly.
- Maintenance and repair of small electrical cable assemblies.
- Protective sleeving for compact wiring harnesses.
- OEM machinery manufacturing and industrial engineering projects.

Frequently Asked Questions
What is the Partex HSMB12GREY heat shrink tubing used for?
The Partex HSMB12GREY is used for electrical insulation, wire protection and cable identification in applications involving fine conductors, small electrical connections and compact wiring assemblies.
What is the shrink ratio of the Partex HSMB12GREY?
The tubing has a 2:1 shrink ratio, meaning its nominal internal diameter reduces from 1.2 mm to approximately 0.6 mm when fully recovered.
How much heat shrink tubing is supplied in one pack?
The Partex HSMB12GREY is supplied in a 20 m pack, allowing installers to cut the tubing into individual lengths for electrical insulation, wire protection and identification applications.
What types of wires can the Partex HSMB12GREY protect?
The tubing is suitable for fine wires and small electrical components that fit within its 1.2 mm supplied diameter and can be securely covered by its nominal 0.6 mm recovered diameter. The correct tubing size should be selected according to the dimensions of the wire or assembly.
How is the Partex HSMB12GREY installed?
Cut the tubing to the required length, position it over the wire or component and apply controlled heat using a suitable hot-air heat gun until the tubing contracts evenly around the surface. Follow the manufacturer's installation instructions and avoid overheating or damaging the underlying wire insulation.
