Why Choose the Partex ECHS224GREEN 2:1 Green Heat Shrink Tubing?
The Partex ECHS224GREEN is a professional 2:1 heat shrink tubing product designed for electrical wire insulation, cable identification, conductor protection and general wiring applications. Supplied in green, with a nominal diameter of 2.4 mm before shrinking and 1.2 mm after shrinking, this heat shrink sleeving provides a practical solution for smaller electrical wires and cable assemblies.
Featuring a 2:1 shrink ratio, the Partex ECHS224GREEN is designed to reduce its diameter when suitable heat is applied, allowing the tubing to conform around compatible conductors, wire joints and cable components. The tubing is particularly useful for professional electrical installation work where a neat, closely fitting insulating sleeve is required.
Supplied in a generous 150 m pack, this green heat shrink tubing is ideal for electrical contractors, control panel manufacturers, industrial maintenance teams and OEM equipment manufacturers requiring substantial quantities of sleeving for ongoing projects. The extended supply length is particularly convenient for repeated cutting and installation across multiple wire termination and cable assembly tasks.
The green colour also makes the ECHS224GREEN useful for visual cable identification and colour-coded wiring systems. Where green sleeving is used for conductor identification, installers should ensure that the colour is appropriate for the relevant wiring standard and application. Green heat shrink tubing alone should not be assumed to provide an approved protective conductor identification system.

The 2:1 shrink ratio is one of the most important specifications when selecting heat shrink tubing. It indicates that the tubing is designed to recover to approximately half its original nominal diameter when the appropriate heat is applied under suitable conditions.
For the Partex ECHS224GREEN, the nominal starting diameter is 2.4 mm, while the nominal fully recovered diameter is 1.2 mm. This makes the tubing suitable for applications where the component being covered can pass through the unshrunk sleeve and has an outside diameter compatible with the tubing's recovery range.
When choosing heat shrink sleeving, it is important to consider both dimensions. The tubing must initially be large enough to slide over the wire, connector or component being covered, but it must also be capable of contracting sufficiently to achieve the intended fit.
For example, a conductor or cable component with an outside diameter below the tubing's nominal supplied diameter may be a suitable candidate, provided the tubing can recover tightly enough around it. Actual suitability depends on the component dimensions, manufacturing tolerances and the manufacturer's recommended sizing guidance.
It is also important to distinguish between cable outside diameter and conductor cross-sectional area. A wire specified as 0.5 mm² or 1.0 mm² does not necessarily have an outside diameter matching those numerical values, because insulation thickness and construction vary. Always measure or verify the overall diameter before selecting heat shrink tubing.
Heat Shrink Sleeving for Electrical Insulation and Wire Protection
Heat shrink tubing is widely used in electrical installations because it provides a convenient method of covering selected sections of wire and cable. The Partex ECHS224GREEN is intended for applications such as insulating compatible conductor sections, finishing cable assemblies and providing additional sleeving around appropriate wiring components.
Once positioned and heated correctly, the tubing contracts around the underlying component to create a close-fitting sleeve. This helps provide a tidy finish and can assist with protecting the covered area from incidental handling and contact.
In electrical control panels and industrial equipment, heat shrink tubing can be used to organise and finish wire assemblies, particularly where multiple conductors are routed into terminal blocks, electrical connectors and control devices.
However, heat shrink tubing should always be selected according to the installation's electrical and environmental requirements. Its suitability as primary electrical insulation, its voltage rating and its resistance to heat, abrasion, chemicals or moisture depend on the specific product specification. These properties should be confirmed using the manufacturer's technical data before use in safety-critical applications.
Green Heat Shrink Tubing for Colour-Coded Cable Identification
The green colour of the Partex ECHS224GREEN makes it useful for cable identification and organised wiring systems where green has an established and permitted meaning. Colour-coded sleeving can help installers visually distinguish cable groups, wiring functions and individual components during assembly and maintenance.
In busy control cabinets and industrial equipment, consistent colour identification can make wiring layouts easier to inspect and maintain. Heat shrink tubing offers the advantage of remaining positioned around the selected wire or component once correctly shrunk, rather than relying on an adhesive label.
It is essential to follow the applicable electrical wiring identification rules. In UK and European electrical installations, green-and-yellow identification is reserved for protective conductors in relevant applications, and plain green sleeving must not be substituted where green-and-yellow identification is required. Any use of plain green sleeving should be consistent with the installation's wiring standards and documentation.
150 m Pack for Electrical Panel Building and Cable Assembly
The 150 m pack makes the Partex ECHS224GREEN particularly suitable for businesses carrying out repeated electrical wiring tasks. Rather than purchasing small quantities of heat shrink tubing for individual jobs, workshops and maintenance departments can keep a substantial supply available for cutting into application-specific lengths.
For electrical control panel builders, this is useful when producing multiple panels or assemblies that require consistent sleeving dimensions and colour identification. OEM manufacturers can also benefit from keeping a standard heat shrink product available for recurring wiring operations.
In industrial maintenance environments, a bulk supply helps ensure suitable sleeving is available for planned servicing and repairs. The tubing can be cut to the length required for each application, helping minimise unnecessary material use.
Before ordering, users should confirm whether the product's supplied packaging and dispensing format meet their storage and handling requirements. The stated 150 m quantity refers to the total supplied tubing length.
How to Install Partex ECHS224GREEN Heat Shrink Tubing
Correct installation helps ensure the tubing shrinks evenly and fits the intended wire or component. The following general procedure can be used as a guide, subject to the manufacturer's specific instructions.
- Check the dimensions: Confirm that the component fits through the 2.4 mm nominal supplied diameter and that the 1.2 mm nominal recovered diameter is suitable for the intended fit.
- Cut the tubing: Measure and cut an appropriate length, allowing for any longitudinal shrinkage specified by the manufacturer.
- Position the sleeve: Slide the tubing over the conductor or component before completing any connection that would prevent installation.
- Apply controlled heat: Use a suitable heat gun or approved heating method, following the manufacturer's recommended shrink temperature and heating instructions.
- Heat evenly: Move the heat source as necessary to encourage uniform recovery without overheating the tubing or damaging the underlying insulation.
- Allow to cool: Let the tubing cool before handling or placing the cable assembly into service.
- Inspect the result: Check that the tubing is correctly positioned, evenly recovered and free from visible damage.
Never use an uncontrolled flame or excessive heat where it could damage electrical insulation or create a fire hazard. Electrical circuits should be made safe before installation or maintenance work begins.
