Why Choose the Partex HS2127RED 2:1 Heat Shrink Tubing?
The Partex HS2127RED is a versatile 2:1 heat shrink tubing solution designed for electrical insulation, wire identification, cable protection and professional electrical installations. Featuring a nominal expanded internal diameter of 12.7 mm and a nominal fully recovered internal diameter of 6.3 mm, this red heat shrink sleeving is suitable for appropriately sized electrical conductors, cable connections, wiring harnesses and electrical assemblies.
With its 2:1 shrink ratio, the Partex HS2127RED can contract to approximately half its original internal diameter when correctly heated, creating a close-fitting protective sleeve around compatible cables and components. This makes it a practical choice for insulating electrical connections, providing light abrasion protection and maintaining a neat, professional finish on wiring installations in electrical control panels, machinery and industrial equipment.
The distinctive red finish supports visual wire identification, colour-coded cable management and organised electrical installations. Supplied in a convenient 50 metre pack, the HS2127RED provides electricians, electrical panel builders, OEM manufacturers and industrial maintenance engineers with a practical supply of heat shrink tubing for installation, assembly and maintenance work.

Professional Heat Shrink Insulation and Red Cable Identification for Electrical Installations
The Partex HS2127RED 2:1 heat shrink tubing is designed for applications requiring a protective sleeve around suitably sized electrical cables, conductors and components. Its 12.7 mm nominal expanded internal diameter allows the tubing to be positioned over compatible cables and connections, while its 6.3 mm nominal fully recovered internal diameter enables it to contract around suitable underlying surfaces when correctly heated.
During installation, a suitable length of tubing is cut and positioned over the cable or component before controlled heat is applied. As the tubing shrinks, it conforms to the underlying surface, helping provide electrical insulation and protection against incidental contact, light abrasion and handling damage. Correct sizing is essential: the tubing must pass over the component before shrinking and recover sufficiently to achieve the required finished fit. The stated recovered diameter refers to nominal unrestricted recovery rather than a guaranteed final diameter when fitted over a cable.
The red colour provides a clear visual identification option for selected conductors, cable groups and electrical assemblies. Red heat shrink sleeving can support site-specific cable identification systems and organised wiring arrangements. It may also be useful in applications where red is assigned to a particular circuit or cable function. However, sleeve colour alone must not be used to establish a conductor's electrical function, and installers should always follow applicable wiring regulations and identification requirements.
With 50 metres supplied per pack, the HS2127RED is a practical choice for electrical panel building, industrial equipment manufacturing and maintenance departments. The tubing can be cut into individual sleeves of the required length, allowing installers to prepare consistent cable protection and identification solutions for repeated wiring tasks while reducing unnecessary material waste.
For installations requiring a specified insulation voltage, operating temperature range, flame-retardancy classification, chemical resistance or moisture sealing, the relevant Partex technical specifications should be confirmed before use. The 2:1 shrink ratio describes dimensional recovery and does not independently establish these additional performance characteristics or confirm an adhesive lining.

Frequently Asked Questions
What is the Partex HS2127RED heat shrink tubing used for?
The Partex HS2127RED is designed for insulating, identifying and protecting electrical wires and components. It is particularly useful for electrical control panels, industrial equipment wiring, cable harnesses and electrical assemblies.
What size is the Partex HS2127RED heat shrink tubing?
The tubing has a nominal 12.7 mm expanded internal diameter and a 6.3 mm fully recovered internal diameter, making it suitable for appropriately sized electrical conductors, connections and components.
What does a 2:1 heat shrink ratio mean?
A 2:1 shrink ratio means the tubing can recover to approximately half its original internal diameter when correctly heated. For the HS2127RED, this corresponds to a nominal reduction from 12.7 mm to 6.3 mm.
What colour is the Partex HS2127RED tubing?
The HS2127RED is red, making it useful for visual wire identification, colour-coded cable management and electrical installations requiring red heat shrink sleeving.
How much heat shrink tubing is supplied in one pack?
Each pack contains 50 metres of red 2:1 heat shrink tubing, providing a practical quantity for electrical installation, equipment manufacturing and maintenance applications.
Can the Partex HS2127RED tubing be cut to length?
Yes. The tubing can be cut to the required length before installation, allowing individual sleeves to be prepared for different wires, connections and cable identification tasks.
How is the Partex HS2127RED heat shrink tubing installed?
Cut a suitable length of tubing, slide it over the cable or component, then apply heat evenly using an appropriate controlled heat source until the sleeve contracts to the required fit. Avoid overheating the tubing or damaging the underlying cable insulation.
Can this tubing be used for electrical insulation?
Yes. Heat shrink tubing is commonly used for electrical insulation and protective sleeving. However, the HS2127RED should only be used where its confirmed electrical and environmental ratings meet the requirements of the installation.
Can red HS2127RED heat shrink tubing be used for cable identification?
Yes. The red finish can be used to identify selected wires, distinguish cable groups and support organised electrical installations. Always follow applicable wiring standards and identification conventions when assigning colours to conductor functions.
Is the HS2127RED adhesive-lined or waterproof?
The supplied product information does not confirm an adhesive lining or waterproof sealing rating. For applications requiring moisture-resistant or waterproof joints, select heat shrink tubing with a specifically confirmed sealing specification.
