HS248BLUE Partex 2:1 heat shrink tubing, 4.8/2.4mm, blue, pack 75m

Why Choose the Partex HS248BLUE 2:1 Blue Heat Shrink Tubing?

The Partex HS248BLUE is a versatile blue 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 4.8 mm, with a nominal recovered diameter of 2.4 mm. This size provides a practical option for electrical conductors, cable harnesses and wiring connections where a fitted protective sleeve is required.

The blue colour offers a clear visual identification option for electrical wiring and cable management, helping installers distinguish selected conductors or cable groups within an established colour-coding system. Supplied in a 75 m pack, the HS248BLUE 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.
• 4.8 mm supplied diameter provides a practical sleeving size for appropriately sized electrical wires and connections.
• 2.4 mm nominal recovered diameter allows a close-fitting sleeve around compatible components.
• Blue colour supports visual cable identification and colour-coded wiring arrangements.
• Heat-activated recovery provides a fitted sleeve without a separate mechanical fastening mechanism.
• Useful 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.
• 75 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 Identification for Electrical Control Systems

Effective cable insulation and identification help maintain organised electrical installations, improve wiring accessibility and simplify equipment maintenance. The Partex HS248BLUE 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 4.8 mm supplied diameter, 2.4 mm recovered diameter and 2:1 shrink ratio makes this tubing relevant to electrical conductors and wiring connections requiring a larger sleeve than smaller heat shrink sizes. 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 blue finish is particularly useful where a documented colour-coding system is used to distinguish conductors, cable groups or wiring functions. It can support efficient identification during installation, inspection and maintenance, although the colour alone does not establish the electrical function of a conductor.

For example, blue sleeving may be selected for a designated group of control wiring within a documented panel identification scheme. Where conductor colours are prescribed by applicable electrical standards, the installer must ensure that the finished identification remains compliant. Blue sleeving should not be assumed to identify a neutral conductor unless that use is appropriate to the installation and its applicable requirements.

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.
