Why Choose the Partex HS248GREY 2:1 Heat Shrink Tubing?
The Partex HS248GREY 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 4.8 mm and a fully recovered internal diameter of 2.4 mm, this grey heat shrink sleeving is suitable for appropriately sized electrical conductors, wiring connections and cable assemblies.
With its 2:1 shrink ratio, the Partex HS248GREY can contract to approximately half its original internal diameter when correctly heated, creating a close-fitting protective sleeve around compatible wires and components. This makes it a practical choice for insulating electrical connections, protecting cable sections against light abrasion and providing a neat, professional finish to wiring installations in control panels, machinery and industrial equipment.
The professional grey finish supports visual wire identification, colour-coded cable management and organised electrical installations. Supplied in a convenient 75 metre pack, the HS248GREY provides electricians, panel builders, electronics technicians, 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 Grey Cable Identification for Electrical Installations
The Partex HS248GREY 2:1 heat shrink tubing is designed for applications requiring a protective sleeve around appropriately sized electrical wires and components. Its 4.8 mm nominal expanded internal diameter allows the tubing to be positioned over compatible conductors and connections, while its 2.4 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 grey colour provides a discreet, neutral appearance that works particularly well in industrial control panels, machinery wiring and electrical equipment assemblies. It can also support colour-coded cable identification systems where grey is assigned to a particular wiring group or function. Installers should follow applicable electrical wiring regulations and site-specific identification conventions rather than relying on sleeve colour alone.
With 75 metres supplied per pack, the HS248GREY 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.
