Why Choose the Partex HS232BLACK 2:1 Black Heat Shrink Tubing?
The Partex HS232BLACK is a versatile black 2:1 heat shrink tubing product designed for electrical wire sleeving, cable identification and protection of suitably sized wiring and connections. Manufactured by Partex, this heat shrink sleeving provides a practical cable management solution for electricians, control panel builders, industrial maintenance engineers and electrical equipment manufacturers requiring neat, close-fitting cable coverings.
Featuring a 2:1 shrink ratio, the tubing reduces in diameter when heated, allowing it to conform around compatible wires and components. The nominal supplied diameter is 3.2 mm, with a nominal recovered diameter of 1.6 mm. This size provides a practical option for small electrical conductors, cable harnesses and wiring connections where a fitted protective sleeve is required.
The black colour provides a discreet, professional appearance for electrical wiring and cable management, helping maintain a consistent finish across cable assemblies and control panel installations. Supplied in a 150 m pack, the HS232BLACK is suitable for repeated cutting and installation tasks in electrical panel assembly, cable harness production, equipment manufacturing and maintenance operations.
Key Advantages
- 2:1 heat shrink ratio allows the tubing to reduce to approximately half its original diameter when correctly recovered.
- 3.2 mm supplied diameter provides a practical sleeving size for appropriately sized electrical wires and connections.
- 1.6 mm nominal recovered diameter allows a close-fitting sleeve around compatible components.
- Black colour provides a discreet and consistent appearance for electrical installations and cable assemblies.
- Heat-activated recovery provides a fitted sleeve without a separate mechanical fastening mechanism.
- Suitable for wire sleeving, cable organisation and protection against incidental contact and light abrasion when correctly specified.
- Cut-to-length flexibility allows individual sleeves to be prepared for different installation requirements.
- 150 m pack quantity supports repeated use in electrical assembly, installation and maintenance projects.
- Practical for control panel manufacturing, industrial wiring and cable harness production.

Reliable Cable Sleeving and Protection for Electrical Control Systems
Effective cable insulation and identification help maintain organised electrical installations, improve wiring accessibility and simplify equipment maintenance. The Partex HS232BLACK provides a heat-shrinkable sleeve that can be cut to length, positioned over a suitable wire or connection and heated to achieve a close fit. This makes it a practical option for electrical wiring in control panels, industrial automation equipment and machinery assemblies.
The combination of a 3.2 mm supplied diameter, 1.6 mm recovered diameter and 2:1 shrink ratio makes this tubing relevant to small electrical conductors and wiring connections. The supplied diameter must be large enough to pass over the wire or component before heating, while the recovered diameter must be suitable for achieving the intended finished fit. Installers should also consider any terminals, connectors or other components that the tubing must pass over during assembly.
In electrical control panels, heat shrink tubing can help provide a tidy finish to wiring assemblies and protect suitable sections of cable from incidental contact and light mechanical abrasion. The black finish is particularly useful where a consistent appearance is preferred across cable harnesses, machinery wiring and electrical equipment. It can also be incorporated into a documented cable identification scheme where black sleeving is specified.
Before installation, users should confirm the required electrical insulation rating, recovery temperature, operating temperature, material compatibility and environmental suitability against the manufacturer's technical documentation. A suitable heat source should be applied evenly according to the manufacturer's instructions, avoiding overheating or damage to the underlying cable insulation. Black colour alone does not establish UV resistance, weather resistance or outdoor suitability.
Typical Applications
