Why Choose the Partex HSMB32BLACK 2:1 Black Heat Shrink Tubing?
The Partex HSMB32BLACK is a professional black 2:1 heat shrink tubing designed for electrical insulation, wire protection and the finishing of cable connections. Featuring a nominal supplied diameter of 3.2 mm and a nominal recovered diameter of 1.6 mm, this heat shrink tubing contracts when heated to provide a close-fitting protective covering around appropriately sized conductors and electrical components.
Designed for professional electrical installation, cable management and maintenance applications, Partex heat shrink tubing is suitable for industrial control panels, machinery wiring, electronic equipment and electrical assemblies. Its black finish provides a neat, discreet appearance while helping protect compatible wiring against everyday handling and abrasion.
Supplied in a convenient 15 m pack, the HSMB32BLACK provides material for repeated cable insulation, wiring repairs and electrical assembly tasks. Its 3.2/1.6 mm nominal dimensions make it particularly useful for small-diameter cables, individual conductors and electrical connections where a compact, professional finish is required.
Key Advantages
- 2:1 heat shrink ratio allows the tubing to recover to approximately half its original nominal diameter.
- 3.2 mm supplied diameter accommodates appropriately sized small conductors and electrical connections.
- 1.6 mm nominal recovered diameter provides a close-fitting covering around compatible wires.

Reliable Cable Insulation for Industrial Control and Automation Systems
Heat shrink tubing provides a practical method of insulating and protecting electrical wiring by contracting around a conductor or component when controlled heat is applied. The Partex HSMB32BLACK features a nominal 2:1 shrink ratio, allowing its diameter to reduce from approximately 3.2 mm to 1.6 mm when fully recovered. This makes it useful for small cable connections, conductor coverings and wiring assemblies where a close-fitting protective sleeve is required.
In industrial automation and electrical control systems, heat shrink tubing can help protect exposed connection areas, organise wire harnesses and provide a tidy finish to completed electrical assemblies. The black colour is particularly useful where a discreet appearance is preferred. Installers should ensure that the tubing passes over the largest part of the connection before shrinking and can recover sufficiently around the smallest section. Applications requiring a specified voltage rating, temperature resistance, flame classification or environmental sealing should be checked against the applicable Partex technical documentation.
Typical Applications
- Electrical wire insulation and conductor protection.
- Industrial control panel wiring and assembly.
- Small cable joints and electrical connection coverings.
- Machinery wiring and industrial automation equipment.
- Wire harness assembly and cable organisation.
- Electrical maintenance and cable repair work.
- Electronic equipment wiring and small cable assemblies.
- Professional finishing of electrical terminations and compatible conductors.
