Why Choose the Partex HS224GREY 2:1 Heat Shrink Tubing?
The Partex HS224GREY 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 2.4 mm and a fully recovered internal diameter of 1.2 mm, this grey heat shrink sleeving is particularly suitable for small electrical conductors, wiring connections and compact cable assemblies.
With its 2:1 shrink ratio, the Partex HS224GREY contracts to approximately half its original internal diameter when correctly heated, creating a close-fitting protective sleeve around appropriately sized wires and components. This makes it a practical choice for insulating conductors, protecting small electrical joints, providing light abrasion protection and maintaining neat wiring arrangements in control panels, electronics and industrial equipment.
The professional grey finish supports visual wire identification, colour-coded cable management and organised electrical installations. Supplied in a generous 150 metre pack, the HS224GREY provides a convenient solution for electricians, electrical panel builders, electronics technicians, OEM manufacturers and industrial maintenance engineers who require consistent access to heat shrink tubing for installation, assembly and maintenance work.

Professional Heat Shrink Insulation and Grey Cable Identification for Electrical Installations
The Partex HS224GREY 2:1 heat shrink tubing is designed for applications requiring a compact, close-fitting protective sleeve around electrical wires and components. Its 2.4 mm nominal expanded internal diameter allows installation over appropriately sized conductors and connections, while its 1.2 mm nominal recovered internal diameter enables the tubing to contract around suitable underlying surfaces.
During installation, a suitable length of tubing is positioned over the wire or component before controlled heat is applied. As the tubing shrinks, it conforms to the shape of the underlying material, helping provide electrical insulation and protection against incidental contact, light abrasion and handling damage. Correct sizing is important: the tubing must fit over the component before shrinking and recover sufficiently to achieve the required finished fit.
The grey colour offers 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.
The generous 150 metre supply makes the HS224GREY particularly suitable for electrical panel building, industrial equipment manufacturing and maintenance departments. The tubing can be cut into individual sleeves of the required length, helping installers work efficiently across repeated wiring tasks while minimising unnecessary material waste.
For applications requiring a specific insulation voltage, operating temperature range, flame-retardancy classification, chemical resistance or moisture sealing, the relevant Partex technical specifications should be confirmed before installation. The 2:1 shrink ratio describes the dimensional recovery of the tubing and does not independently establish these additional performance characteristics.
