Why Choose the Partex HSMB191BLUE 2:1 Blue Heat Shrink Tubing?
The Partex HSMB191BLUE is a professional 2:1 blue heat shrink tubing product designed for electrical insulation, cable protection, conductor identification and professional cable management. Manufactured by Partex, a specialist in cable marking and identification solutions, this heat shrink tubing provides a practical way to protect electrical conductors, insulated connections and cable assemblies while creating neat, organised wiring installations.
Featuring a nominal supplied diameter of 19.1 mm and a nominal recovered diameter of 9.5 mm, the HSMB191BLUE 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 blue finish, the Partex HSMB191BLUE is ideal for electrical control panels, industrial automation, machinery wiring, cable harness manufacturing and general electrical maintenance. Blue sleeving can also support neutral conductor identification where required by the applicable wiring standards, making it a useful choice for professional electrical installations.

Reliable Insulation and Blue Cable Identification
Heat shrink tubing provides a convenient method of protecting electrical cables, insulated connections and wiring assemblies. The Partex HSMB191BLUE features a 2:1 shrink ratio, allowing its nominal diameter to reduce from 19.1 mm to approximately 9.5 mm when heated under appropriate conditions.
The larger supplied diameter makes this tubing particularly useful where a protective sleeve must pass over a cable joint, insulated connector or suitably sized bundle of conductors before shrinking. Once heated, the tubing contracts around the underlying surface to provide a neat protective covering.
The blue finish offers an effective visual identification option for electrical conductors and cable assemblies. In UK and harmonised European electrical installations, blue is commonly used to identify neutral conductors. However, conductor colour conventions can vary between installation types, voltage systems and equipment standards. The HSMB191BLUE should therefore be used only where blue identification is appropriate for the intended application.
When correctly selected and installed, the 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 HSMB191BLUE is intended for applications where standard heat shrink sleeving is appropriate. Do not assume that it provides an adhesive-lined seal, waterproof joint or specific environmental resistance unless those properties are confirmed in the manufacturer's technical documentation.
