Why Choose the Partex ECHS2381BLACK 2:1 Heat Shrink Tubing?
The Partex ECHS2381BLACK is a versatile 2:1 heat shrink tubing designed for electrical insulation, cable protection and wire identification in industrial, commercial and electrical engineering applications. Supplied in a professional black finish, this heat shrink sleeving provides a practical solution for protecting electrical conductors, insulating cable connections and organising larger wiring assemblies.
Featuring a nominal supplied internal diameter of 38.1 mm and a fully recovered internal diameter of 19 mm, the ECHS2381BLACK offers an approximately 2:1 shrink ratio. When suitable heat is applied, the tubing contracts around appropriately sized cables, conductors and electrical components, forming a close-fitting protective sleeve that supports electrical insulation and mechanical protection.
Supplied in a convenient 30 m pack, the Partex ECHS2381BLACK is particularly suitable for electrical panel builders, wiring harness manufacturers, maintenance engineers and industrial production environments. Its larger diameter makes it useful for sleeving compatible cable bundles, larger conductors and electrical assemblies, while the black finish provides a neat, consistent appearance across electrical installations.

Reliable Electrical Insulation and Protection for Larger Cable Assemblies
Heat shrink tubing provides a convenient method of insulating electrical conductors, covering cable joints and protecting wiring assemblies. The Partex ECHS2381BLACK 2:1 heat shrink tubing contracts when suitable heat is applied, allowing the sleeve to conform closely to appropriately sized cables and electrical components. This helps create a neat, organised installation while providing an additional protective layer against everyday mechanical wear.
The 38.1/19 mm diameter configuration makes this tubing suitable for a range of compatible larger electrical cables, insulated connections, wiring harnesses and cable bundles. Its generous supplied diameter allows it to pass over appropriately sized components and cable assemblies before shrinking, while the black finish is useful where black sleeving is specified or a uniform wiring appearance is preferred.
For effective installation, ensure the tubing fits over the cable or component before heating and has sufficient recovery to grip it securely. Apply heat evenly using a suitable controlled heat source and follow the manufacturer's installation guidance. When covering electrical connections, ensure the completed assembly meets the applicable insulation and installation requirements. Heat shrink tubing should not be assumed to provide a waterproof seal unless the relevant sealing properties have been confirmed.
Typical Applications
- Electrical cable insulation and protection.
- Industrial control panel wiring and cable management.
- Protective sleeving for compatible larger cables and conductors.
- Wiring harness manufacturing and assembly.
- Black colour-coded cable and conductor identification.
- Covering compatible cable joints and electrical connections.
- Industrial automation equipment and machinery wiring.
- Electrical maintenance, repairs and production assembly.
