HS2381GREEN Partex 2:1 heat shrink tubing, 38.1/19mm, green, pack 30m

Why Choose the Partex HS2381GREEN 2:1 Green Heat Shrink Tubing?

The Partex HS2381GREEN is a versatile green heat shrink tubing designed for electrical insulation, cable protection, conductor identification and professional cable management. Featuring a 2:1 shrink ratio, this tubing reduces from a nominal supplied internal diameter of 38.1 mm to 19 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 green heat shrink tubing provides a practical solution for protecting electrical connections while supporting clear and consistent cable identification. Its distinctive green colour is useful for custom colour-coded wiring systems, helping electricians, control panel builders and maintenance engineers distinguish designated cable groups and components within industrial installations.

Supplied in a convenient 30 m pack, the HS2381GREEN is suitable for electrical contractors, industrial manufacturers, automation engineers and maintenance professionals requiring a bulk supply of heat shrink sleeving. With its 38.1 mm supplied diameter and 19 mm nominal recovered diameter, it is particularly useful for larger conductors, cable bundles, electrical terminations and protective sleeving applications in industrial and commercial environments.

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 HS2381GREEN combines a practical 2:1 shrink ratio with a larger 38.1 mm supplied internal diameter, making it particularly useful for applications involving larger cables, grouped conductors and electrical connections. Its green finish provides a clearly identifiable appearance across cable assemblies while helping protect the underlying wiring against minor mechanical damage.

Green heat shrink tubing can support custom cable identification systems where the colour is appropriate for the installation. It may be used to distinguish designated cable groups, equipment wiring or components during assembly and maintenance. However, plain green tubing must not be used as a substitute for the required green/yellow identification of protective earth conductors in UK and European harmonised electrical installations. The selected identification method must comply with applicable wiring regulations and must not create confusion about conductor function.

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.
