HSMB254YELLOW Partex 2:1 heat shrink tubing, 25.4/12.7mm, yellow, pack 5m

Why Choose the Partex HSMB254YELLOW 2:1 Yellow Heat Shrink Tubing?

The Partex HSMB254YELLOW is a professional 2:1 yellow heat shrink tubing product designed for electrical insulation, cable protection, wire identification and organised cable management. Manufactured by Partex, a specialist in cable marking and identification solutions, this heat shrink tubing provides a practical way to protect electrical cables, insulated connections and cable assemblies while creating neat, clearly identifiable wiring installations.

Featuring a nominal supplied diameter of 25.4 mm and a nominal recovered diameter of 12.7 mm, the HSMB254YELLOW is suitable for appropriately sized electrical cables, insulated joints, wiring bundles and electrical components. 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 cables and connections.

Supplied in a convenient 5 m pack with a distinctive yellow finish, the Partex HSMB254YELLOW is ideal for electrical control panels, industrial automation, machinery wiring, cable harness manufacturing and general electrical maintenance. The highly visible yellow colour helps distinguish designated cable groups, circuits and equipment connections, supporting efficient identification and organised electrical installations.

Reliable Insulation and High-Visibility Cable Identification

Heat shrink tubing provides a convenient method of protecting electrical cables, insulated connections and wiring assemblies. The Partex HSMB254YELLOW features a 2:1 shrink ratio, allowing its nominal diameter to reduce from 25.4 mm to approximately 12.7 mm when heated under appropriate conditions.

The larger supplied diameter makes this tubing particularly useful where a protective sleeve must pass over an insulated cable joint, connector or suitably sized bundle of conductors before shrinking. Once heated, the tubing contracts around the underlying surface to provide a neat protective covering. Its diameter range makes it a practical option for cable assemblies that require more coverage than smaller heat shrink tubing sizes.

The yellow finish provides a highly visible identification option for designated cable groups, wiring assemblies and equipment connections. This can be particularly useful in industrial control panels, machinery and maintenance environments where clearly distinguishable cable groups help technicians identify wiring during installation, inspection and servicing.

Plain yellow heat shrink tubing should not be confused with green/yellow protective earth identification sleeving. In UK and harmonised European electrical installations, the green/yellow colour combination is reserved for protective conductors. Plain yellow tubing does not provide equivalent protective earth identification and should only be used where the selected colour is appropriate under the applicable wiring standards and installation requirements.

When correctly selected and installed, heat shrink tubing helps provide supplementary insulation and protection against abrasion and general mechanical wear. It can also improve the appearance of wiring assemblies by covering suitable insulated connections and 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 with a supplied diameter large enough to pass over the widest part of the cable or component and 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.

The HSMB254YELLOW should be selected according to the electrical and environmental requirements of the intended application. Do not assume that the tubing provides an adhesive-lined seal, waterproof joint or a specific temperature, voltage or chemical resistance rating unless these properties are confirmed in the manufacturer's technical documentation.
