Why Choose the Partex ECHS2191BLACK 2:1 Black Heat Shrink Tubing?
The Partex ECHS2191BLACK is a professional black 2:1 heat shrink tubing designed for electrical cable insulation, wire protection, cable sleeving and general electrical installation applications. Featuring a nominal supplied diameter of 19.1 mm and a nominal fully recovered diameter of 9.5 mm, this heat shrink sleeving provides a neat, close-fitting protective covering around suitably sized electrical cables, wire bundles, conductor connections and cable assemblies.
The 2:1 shrink ratio allows the tubing to recover to approximately half its original internal diameter when heated correctly. This makes it suitable for covering compatible cables and components where a protective insulating sleeve is required. Its heat-activated recovery helps the tubing conform to the underlying surface, providing an additional layer of electrical insulation while helping protect covered areas against abrasion and general handling wear.
Supplied in a practical 50 m pack, the ECHS2191BLACK is suitable for electrical contractors, control panel manufacturers, industrial equipment builders and maintenance engineers requiring larger-diameter heat shrink sleeving for regular installation work. Its black finish provides a discreet, professional appearance for electrical cables, machinery wiring, equipment connections and cable management applications.
Key Advantages
- 2:1 heat shrink ratio enables controlled diameter reduction for compatible cables and components.
- 19.1 mm nominal supplied diameter accommodates suitably sized electrical cables, wire bundles and connections.
- 9.5 mm nominal fully recovered diameter provides a close-fitting sleeve after correct heat application.
- Black colour creates a discreet, professional finish for electrical installations and cable assemblies.
- Provides an additional insulating covering around compatible electrical conductors and connections.
- Helps protect covered cable surfaces against abrasion and general mechanical handling.
- Suitable for larger cable sections and assemblies than smaller-diameter heat shrink tubing.
- Flexible tubular sleeving can be cut to the required length for individual applications.
- Heat-activated recovery produces a neat finish without conventional tape wrapping.
- 50 m pack quantity supports electrical installation, equipment manufacturing and maintenance work.

Reliable 2:1 Heat Shrink Protection for Larger Electrical Cables and Connections
The Partex ECHS2191BLACK provides a practical solution for insulating and protecting compatible electrical cables, wiring assemblies and conductor connections. The tubing is positioned over the required cable section before controlled heat is applied evenly using suitable hot-air equipment. As the tubing warms, it contracts around the underlying surface, helping create a close-fitting covering that improves the appearance and physical protection of the completed cable assembly.
With a nominal supplied diameter of 19.1 mm and a nominal fully recovered diameter of 9.5 mm, the ECHS2191BLACK is suited to applications requiring a larger-diameter heat shrink sleeve. The tubing should be selected so that it can pass over the cable or connection before heating and recover sufficiently to fit securely afterwards. The 50 m supply length allows installers to prepare individual sleeves for electrical assembly, equipment manufacturing and maintenance work.
The black finish makes this tubing a practical choice for cable assemblies requiring a consistent, discreet appearance. Heat shrink sleeving can provide supplementary insulation and abrasion protection, but it should not be assumed to offer a particular voltage rating, environmental sealing performance or waterproof protection without confirmation of the relevant product specifications.
Typical Applications
- Electrical cable insulation and protection.
- Industrial machinery and equipment wiring.
- Control panel cable management and assembly.
- Protection of compatible cable joints and conductor connections.
- Electrical equipment manufacturing and installation.
- Industrial automation and power distribution wiring assemblies.
- Protective sleeving for compatible cable terminations.
- Wire bundle covering and electrical harness assembly.
- Electrical maintenance, repair and refurbishment.
- Workshop cable preparation and general electrical installation work.

Frequently Asked Questions
What is the Partex ECHS2191BLACK used for?
The Partex ECHS2191BLACK is black heat shrink tubing used for electrical cable insulation, abrasion protection, protective sleeving and covering compatible cable joints, conductor connections and wiring assemblies.
What does the 2:1 shrink ratio mean?
A 2:1 shrink ratio means the tubing can recover to approximately half its original internal diameter when heated correctly. The ECHS2191BLACK has a nominal supplied diameter of 19.1 mm and a nominal fully recovered diameter of 9.5 mm.
What size is the Partex ECHS2191BLACK tubing?
The tubing has a nominal diameter of 19.1 mm before shrinking and 9.5 mm after full recovery. Select it for cables or components that fit inside the tubing before heating and can be gripped securely after shrinking.
How much heat shrink tubing is supplied?
The Partex ECHS2191BLACK is supplied in a 50 m pack. The tubing can be cut into individual lengths to suit electrical installation, cable assembly, manufacturing and maintenance requirements.
How is the ECHS2191BLACK heat shrink tubing installed?
Cut the tubing to the required length, slide it over the compatible cable or component, and apply controlled heat evenly using suitable hot-air equipment until the tubing contracts around the surface. Avoid overheating, protect nearby components and follow appropriate electrical safety procedures.
Is the Partex ECHS2191BLACK suitable for larger electrical cables?
Yes. With a nominal supplied diameter of 19.1 mm and a nominal fully recovered diameter of 9.5 mm, the ECHS2191BLACK is suitable for larger compatible cables and wiring assemblies than smaller-diameter heat shrink products.
