Why Choose the Partex HS2191BLACK 2:1 Black Heat Shrink Tubing?

The Partex HS2191BLACK is a versatile and practical black heat shrink tubing designed for electrical insulation, cable protection, wire identification and professional cable management. Featuring a 2:1 shrink ratio, this tubing reduces from a nominal supplied internal diameter of 19.1 mm to 9.5 mm when fully recovered, providing a close-fitting protective sleeve around appropriately sized cables, wire bundles and electrical components.

Manufactured by Partex, a recognised specialist in cable identification and electrical installation products, this black heat shrink tubing provides an effective solution for protecting electrical connections and improving the finish of cable assemblies. Its black colour provides a discreet, professional appearance, making it particularly suitable for electrical control panels, industrial machinery, cable harnesses and maintenance applications where a consistent finish is required.

Supplied in a convenient 50 m pack, the HS2191BLACK is well suited to electrical contractors, control panel builders, industrial manufacturers and maintenance engineers requiring a bulk supply of protective sleeving. With its 19.1 mm supplied diameter and 9.5 mm nominal recovered diameter, it is particularly useful for larger conductors, cable bundles, electrical terminations and protective sleeving applications in industrial and commercial environments.

Key Advantages

  • 2:1 heat shrink ratio provides a close fit around appropriately sized cables and electrical components.
  • 19.1 mm supplied diameter reducing to approximately 9.5 mm when fully recovered.
  • Black finish provides a neat, professional appearance for cable assemblies and electrical installations.
  • 50 m bulk pack suitable for professional installations, manufacturing and maintenance environments.
  • Helps provide electrical insulation and mechanical protection for suitable conductors and connections.
  • Protective sleeving helps reduce exposure to abrasion and everyday mechanical wear.
  • Suitable for covering appropriately sized cable bundles and electrical terminations.
  • Can be cut to the required length for individual insulation and cable protection tasks.

Reliable Electrical Insulation and Cable Protection

Heat shrink tubing is widely used in electrical and industrial installations to provide protective sleeving around conductors, cable connections and electrical components. When suitable heat is applied, the tubing contracts around the underlying component, creating a neat, close-fitting covering that helps protect against abrasion and provides additional electrical insulation where appropriate.

The Partex HS2191BLACK combines a practical 2:1 shrink ratio with a larger 19.1 mm supplied internal diameter, making it particularly useful for applications involving larger cables, grouped conductors and electrical connections. Its black finish provides a consistent appearance across cable assemblies while helping protect the underlying wiring against minor mechanical damage.

Black heat shrink tubing is commonly selected for general-purpose protective sleeving, cable harness assembly and electrical maintenance applications. It can help organise cable bundles, cover suitable connection areas and provide a tidy finish to electrical equipment. Unlike dedicated colour-coded identification sleeving, black tubing is particularly useful where a neutral appearance is preferred and specific conductor identification colours are not required.

For effective installation, select tubing with a supplied internal diameter large enough to pass over the intended cable, connector or component and a recovered diameter suitable for the required fit. Cut the tubing to length and apply controlled, even heat using an appropriate heat gun, following the manufacturer's installation recommendations and avoiding excessive heating of the underlying cable insulation. Where a moisture-resistant seal or environmental barrier is required, a suitably specified sealing product should be selected rather than assuming standard heat shrink tubing is waterproof.

Typical Applications

  • Electrical wire and cable insulation.
  • Protective sleeving for larger conductors and cable bundles.
  • Electrical control panel wiring and assembly.
  • Industrial automation and machine control systems.
  • Protection of suitable cable joints and electrical connections.
  • Wire harness manufacturing and cable management.
  • Electrical equipment manufacturing and assembly.
  • Maintenance and repair of electrical wiring.
  • Protective covering for appropriately sized cable terminations.
  • Commercial and industrial electrical installations.

Frequently Asked Questions

What is the Partex HS2191BLACK used for?

The Partex HS2191BLACK is used for electrical insulation, cable protection and protective sleeving. Its larger supplied diameter makes it particularly useful for appropriately sized cable bundles, electrical connections, control panel wiring and industrial cable management applications.

What is the shrink ratio of the Partex HS2191BLACK?

The tubing has a 2:1 shrink ratio, with a nominal supplied internal diameter of 19.1 mm and a nominal recovered internal diameter of 9.5 mm when fully shrunk under suitable heating conditions.

How much heat shrink tubing is supplied?

The HS2191BLACK is supplied in a 50 m pack, providing a convenient bulk quantity for electrical contractors, control panel builders, industrial manufacturers and maintenance applications.

Can Partex HS2191BLACK be used for cable bundles and electrical connections?

Yes. The 19.1 mm supplied internal diameter allows the tubing to be positioned over suitably sized cable bundles, conductors and electrical connections. When heated, it contracts towards a nominal recovered diameter of 9.5 mm, helping provide a close-fitting protective sleeve. The tubing should be selected according to the dimensions of the application and the required level of insulation and protection.

How is Partex HS2191BLACK heat shrink tubing installed?

Cut the tubing to the required length, position it over a suitably sized cable, conductor bundle or electrical component and apply controlled, even heat using an appropriate heat gun. The tubing contracts around the component to provide a close-fitting black protective sleeve.
