Why Choose the Partex HS2381RED 2:1 Heat Shrink Tubing?
The Partex HS2381RED is a versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, conductor identification and professional cable management applications. Featuring a distinctive red finish and heat-activated shrinking properties, this tubing provides a practical solution for insulating, protecting and organising electrical conductors in industrial, commercial and general electrical installations.
As part of the Partex HS2 heat shrink tubing range, the HS2381RED contracts when heated, forming a close-fitting sleeve around compatible cables, wiring bundles and electrical components. Its 2:1 nominal shrink ratio allows the tubing to recover to approximately half its original internal diameter, providing flexibility when selecting protective sleeves for different cable sizes and electrical assemblies.
With a nominal supplied internal diameter of 38.1 mm and a nominal recovered internal diameter of 19 mm, the HS2381RED is particularly suitable for larger electrical cables, wiring harnesses, cable bundles and colour-coded identification applications. Supplied in a convenient 30 m pack, it is ideal for electrical panel builders, cable harness manufacturers, maintenance engineers and industrial production environments requiring red heat shrink tubing.

Reliable Electrical Insulation and Cable Identification
The Partex HS2381RED provides a practical method of insulating and protecting electrical cables while supporting clear cable identification. When suitable heat is applied, the tubing contracts around the cable or component, creating a close-fitting sleeve that helps protect the underlying surface against incidental abrasion and contact. Its flexible format makes it suitable for cable preparation, electrical assembly and maintenance work where a protective covering is required.
The 2:1 shrink ratio offers flexibility when working with different cable diameters, while the distinctive red finish helps installers visually distinguish wiring groups and cable identification categories within electrical control panels and cable harnesses. Red tubing may also support positive conductor identification in DC electrical systems where this colour convention is appropriate, subject to the applicable wiring standards and installation requirements.
The 30 m pack is particularly useful for repetitive cable preparation, electrical manufacturing and maintenance applications where tubing is cut to individual lengths as required. Its 38.1 mm supplied diameter makes it a practical choice for compatible larger cable assemblies, wiring bundles and electrical components requiring a neat protective sleeve. The tubing should be selected according to the outside diameter of the component and the required recovered fit.
