Why Choose the Partex ECHS2381YELLOW 2:1 Heat Shrink Tubing?
The Partex ECHS2381YELLOW is a professional 2:1 heat shrink tubing designed for electrical insulation, cable protection, wire identification and cable management. Supplied in yellow, this heat shrink sleeve has a nominal supplied diameter of 38.1 mm and a nominal fully recovered diameter of 19 mm, making it suitable for compatible larger electrical cables, conductors and cable assemblies.
Designed for electrical installation, industrial panel building and cable assembly, the ECHS2381YELLOW contracts when heated to form a close-fitting protective sleeve around appropriately sized cables and components. Its 2:1 shrink ratio means the tubing can reduce to approximately half its original internal diameter, helping provide a neat, professional finish while offering an additional protective covering for electrical wiring.
With a 38.1/19 mm diameter specification and a convenient 30 m pack length, the Partex ECHS2381YELLOW is particularly suitable for electrical panel builders, wiring harness manufacturers, maintenance engineers and OEM production environments. Its yellow finish provides clear visual identification within appropriately designed cable marking systems, while the supplied length allows installers to cut individual sections to suit different applications.

Reliable Electrical Insulation and Cable Protection
Heat shrink tubing provides a practical method of insulating, identifying and protecting electrical cables, wiring assemblies and compatible electrical connections. The Partex ECHS2381YELLOW contracts when heat is applied, allowing the sleeve to conform closely to appropriately sized cables and components. Its 2:1 shrink ratio makes it useful for installations requiring a protective covering and a clean, professional cable finish.
The yellow finish provides clear visual distinction within a planned cable identification system, making the tubing useful for industrial equipment, control panels and wiring harnesses. Yellow sleeving can help identify selected cable groups or circuits where the chosen colour scheme is permitted by applicable wiring regulations. It should not be assumed to indicate a particular conductor function without reference to the relevant electrical standard or installation documentation.
The ECHS2381YELLOW is particularly useful for electrical panel builders, automation engineers and maintenance professionals working with larger cable assemblies that require protective sleeving. Its 30 m supply length enables installers to prepare multiple sections for different applications. For best results, select the tubing according to the cable's outside diameter, ensure it can pass over the component before shrinking and apply heat evenly using a suitable heat gun. Always follow the manufacturer's installation guidance and verify that the tubing meets the electrical and environmental requirements of the intended application.
Typical Applications
- Electrical cable insulation and protection.
- Colour-coded cable and conductor identification where appropriate.
- Industrial electrical control panels and cabinets.
- PLC wiring and industrial automation equipment.
- Wiring harness manufacturing and cable assembly.
- Protective sleeving for compatible larger cable connections.
- OEM electrical equipment and machinery manufacturing.
- Electrical maintenance, repair and workshop applications.
- Cable management in industrial machinery and control systems.
- Professional finishing of suitably sized cable assemblies.

Frequently Asked Questions
What is the Partex ECHS2381YELLOW used for?
The Partex ECHS2381YELLOW is yellow heat shrink tubing used for electrical insulation, cable protection, wire identification and the professional finishing of compatible electrical cables and wiring assemblies.
What does the 2:1 shrink ratio mean?
A 2:1 shrink ratio means the tubing can reduce to approximately half its original internal diameter when fully recovered. The ECHS2381YELLOW has a nominal supplied diameter of 38.1 mm and a specified fully recovered diameter of 19 mm.
What size cable is the ECHS2381YELLOW suitable for?
The tubing has a nominal supplied diameter of 38.1 mm and a fully recovered diameter of 19 mm. It should be selected for cables or components that the tubing can pass over before heating and grip adequately after shrinking. Check the cable's outside diameter, including any connectors or components the sleeve must pass over.
Can the yellow tubing be used for cable identification?
Yes. The yellow finish can help distinguish cables and wiring assemblies within an appropriate colour-coding system. However, conductor identification must comply with applicable electrical wiring regulations and site requirements. Yellow sleeving should not be assumed to indicate a specific electrical function without reference to the relevant wiring standard.
How much heat shrink tubing is supplied in one pack?
The Partex ECHS2381YELLOW is supplied in a 30 m pack, making it suitable for electrical workshops, control panel assembly, wiring harness production and repeated industrial maintenance applications.
