Partex ECHS2381BROWN brown 2:1 heat shrink tubing with a 38.1 mm supplied internal diameter and 19 mm recovered internal diameter, supplied in a 30 m pack for electrical insulation, cable protection and colour-coded conductor identification.
£121.65
The Partex ECHS2381BROWN is a versatile 2:1 brown heat shrink tubing designed for electrical insulation, cable protection and colour-coded conductor identification in industrial and commercial electrical installations. Part of the Partex ECHS heat shrink tubing range, this protective sleeving provides a practical solution for covering electrical cables, protecting insulated connections and achieving a neat, professional finish on wiring assemblies, cable harnesses and electrical equipment.
Featuring a nominal supplied internal diameter of 38.1 mm and a nominal fully recovered internal diameter of 19 mm, the ECHS2381BROWN offers an approximately 2:1 shrink ratio. When suitable heat is applied, the tubing contracts around appropriately sized cables and components, creating a close-fitting protective covering that helps reduce abrasion, mechanical wear and damage caused by routine handling. Its larger diameter makes it particularly useful for sleeving compatible multicore cables, cable bundles, insulated joints and wiring harness assemblies.
The distinctive brown finish supports clear conductor identification and organised cable management. Brown is commonly used for line conductor identification in UK and European harmonised electrical installations, making this tubing suitable for appropriate conductor marking applications. Supplied in a convenient 30 m pack, the ECHS2381BROWN is an excellent choice for electrical contractors, control panel manufacturers, industrial maintenance engineers and OEM equipment builders requiring practical heat shrink sleeving for cable preparation, electrical assembly and maintenance work.
Heat shrink tubing is widely used in electrical engineering, industrial automation and control panel manufacturing to provide an insulating and protective covering around cables, electrical connections and wiring assemblies. When heated using a suitable controlled heat source, the tubing contracts in diameter to fit around the underlying cable or component. This creates a neat protective sleeve that helps reduce exposure to abrasion, handling damage and mechanical wear while supporting professional cable management.
The Partex ECHS2381BROWN 2:1 brown heat shrink tubing has a nominal internal diameter of 38.1 mm before shrinking and a nominal fully recovered diameter of 19 mm. These dimensions make it suitable for appropriately sized larger electrical cables, insulated joints, cable bundles and wiring assemblies. The brown finish provides a consistent appearance and can support conductor identification in electrical systems where brown denotes a line conductor, including suitable three-phase distribution equipment and control panel installations.
For dependable results, the tubing should have sufficient initial diameter to pass over the largest part of the assembly and an appropriate recovered diameter to achieve the required fit. Apply heat evenly using suitable equipment and avoid excessive temperatures that could damage the tubing or underlying insulation. In UK harmonised wiring systems, brown is commonly used for the line conductor in single-phase circuits and the L1 line conductor in three-phase circuits. However, conductor identification must always follow the applicable wiring standards and installation requirements. Standard heat shrink tubing should not be assumed to provide a waterproof seal unless a suitable sealing construction is specified.

The Partex ECHS2381BROWN is used for electrical insulation, cable protection, connection sleeving and colour-coded conductor identification. Its nominal 38.1 mm supplied internal diameter makes it suitable for appropriately sized larger cables, insulated connections and cable harness assemblies.
A 2:1 shrink ratio means the tubing can reduce to approximately half its original internal diameter when fully recovered under suitable heating conditions. The ECHS2381BROWN has a nominal supplied internal diameter of 38.1 mm and a nominal recovered internal diameter of 19 mm.
Brown heat shrink tubing can be used for conductor identification where brown is the required colour. In UK harmonised electrical wiring systems, brown is commonly associated with the line conductor in single-phase circuits and the L1 line conductor in three-phase circuits. The selected identification method must comply with applicable electrical wiring standards and installation requirements.
Cut the tubing to the required length, slide it over the cable or component and apply controlled heat evenly using a suitable heat gun. The tubing contracts around the component as it heats. Ensure the selected tubing dimensions are compatible with the assembly and avoid overheating the tubing or underlying cable insulation.
The Partex ECHS2381BROWN is supplied in a 30 m pack, providing a practical quantity for industrial wiring, cable harness manufacturing, electrical panel assembly, conductor identification and maintenance applications.
Partex cable identification and installation accessories provide practical solutions for electrical engineers, industrial maintenance teams and control panel manufacturers. The ECHS2381BROWN brown 2:1 heat shrink tubing combines convenient installation, clear conductor identification and practical cable protection for professional electrical wiring, cable harness production and industrial maintenance applications.
