Why Choose the Partex HS295BLUE 2:1 Heat Shrink Tubing?
The Partex HS295BLUE is a versatile 2:1 heat shrink tubing solution designed for electrical insulation, wire identification, cable protection and professional electrical installations. Featuring a nominal expanded internal diameter of 9.5 mm and a nominal recovered internal diameter of 4.7 mm, this blue heat shrink sleeving is suitable for appropriately sized electrical conductors, cable connections and wiring assemblies.
With its 2:1 shrink ratio, the Partex HS295BLUE contracts to approximately half its original internal diameter when correctly heated, creating a close-fitting protective sleeve around compatible cables and components. This makes it a practical choice for insulating electrical connections, providing light abrasion protection and maintaining a neat, professional finish on wiring installations in electrical control panels, machinery and industrial equipment.
The distinctive blue finish supports visual wire identification, colour-coded cable management and organised electrical installations. Supplied in a convenient 75 metre pack, the HS295BLUE provides electricians, electrical panel builders, OEM manufacturers and industrial maintenance engineers with a practical supply of heat shrink tubing for installation, assembly and maintenance work.

Professional Heat Shrink Insulation and Blue Cable Identification for Electrical Installations
The Partex HS295BLUE 2:1 heat shrink tubing is designed for applications requiring a protective sleeve around suitably sized electrical cables, conductors and components. Its 9.5 mm nominal expanded internal diameter allows the tubing to be positioned over compatible cables and connections, while its 4.7 mm nominal recovered internal diameter enables it to contract around suitable underlying surfaces when correctly heated.
During installation, a suitable length of tubing is cut and positioned over the wire or component before controlled heat is applied. As the tubing shrinks, it conforms to the underlying surface, helping provide electrical insulation and protection against incidental contact, light abrasion and handling damage. Correct sizing is essential: the tubing must pass over the component before shrinking and recover sufficiently to achieve the required finished fit.
The blue colour provides a clear visual identification option for selected conductors, cable groups and electrical assemblies. Blue heat shrink sleeving can support site-specific cable identification systems and organised wiring arrangements. In UK and European electrical installations, blue is commonly associated with neutral conductors, but sleeve colour alone must not be used to establish a conductor's function. Installers should always follow the applicable wiring regulations and identification requirements.
With 75 metres supplied per pack, the HS295BLUE is a practical choice for electrical panel building, industrial equipment manufacturing and maintenance departments. The tubing can be cut into individual sleeves of the required length, allowing installers to prepare consistent cable protection and identification solutions for repeated wiring tasks while reducing unnecessary material waste.
For installations requiring a specified insulation voltage, operating temperature range, flame-retardancy classification, chemical resistance or moisture sealing, the relevant Partex technical specifications should be confirmed before use. The 2:1 shrink ratio describes dimensional recovery and does not independently establish these additional performance characteristics or confirm an adhesive lining.
