HS2191BLUE Partex 2:1 heat shrink tubing, 19.100000000000001/9.5mm, blue, pack 50m

Why Choose the Partex HS2191BLUE 2:1 Heat Shrink Tubing?

The Partex HS2191BLUE is a versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection, conductor identification and professional cable management applications. Featuring a distinctive blue 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 HS2191BLUE contracts when heated, forming a close-fitting sleeve around compatible wires, cables and 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 conductor sizes and electrical assemblies.

With a nominal supplied internal diameter of 19.1 mm and a nominal recovered internal diameter of 9.5 mm, the HS2191BLUE is particularly suitable for larger electrical conductors, cable assemblies, wiring bundles and colour-coded identification applications. Supplied in a convenient 50 m pack, it is ideal for electrical panel builders, cable harness manufacturers, maintenance engineers and industrial production environments requiring blue heat shrink tubing.

Key Advantages

• 2:1 heat shrink ratio allows the tubing to contract to approximately half its supplied internal diameter.
• 19.1 mm supplied diameter accommodates compatible larger electrical conductors, cable assemblies and wiring bundles.
• 9.5 mm recovered diameter provides a close-fitting sleeve when correctly applied.
• Blue colour supports visual cable identification, conductor differentiation and organised wiring installations.
• Electrical insulation and mechanical protection help protect compatible conductors and cable components.
• Heat-activated installation provides a neat, conforming finish without mechanical fasteners.
• Cut-to-length flexibility allows individual sleeves to be prepared for different installation requirements.
• 50 m pack quantity provides a practical supply for installation, manufacturing and maintenance tasks.

Reliable Electrical Insulation and Cable Identification

The Partex HS2191BLUE provides an effective method of insulating and protecting electrical conductors 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 conductor diameters, while the distinctive blue finish helps installers visually distinguish wiring groups and cable identification categories within electrical control panels and cable harnesses. Blue tubing can also support neutral conductor identification in installations where this colour convention is required, provided the application complies with relevant electrical wiring standards.

The 50 m pack is particularly useful for repetitive cable preparation, electrical manufacturing and maintenance applications where tubing is cut to individual lengths as required. Its 19.1 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.
