HS21016RED Partex 2:1 heat shrink tubing, 101.6/50.8mm, red, pack 15m

Why Choose the Partex HS21016RED 2:1 Red Heat Shrink Tubing?

The Partex HS21016RED is a professional red heat shrink tubing designed for electrical insulation, cable protection and colour-coded identification of cables, conductors and electrical connections. Featuring a 2:1 shrink ratio, this tubing contracts when heated to provide a close-fitting protective sleeve around compatible cables, cable bundles and electrical components.

Designed for professional cable management and electrical installation applications, Partex heat shrink tubing is suitable for industrial control panels, electrical distribution assemblies, machinery wiring and maintenance work. Its distinctive red finish provides clear visual identification, making it particularly useful for colour-coded cable management and applications where specific conductors or cable groups need to be easily distinguished.

With a nominal supplied diameter of 101.6 mm, a recovered diameter of approximately 50.8 mm and a 15 m pack length, the HS21016RED provides a practical solution for large cable assemblies, electrical terminations, wire harnesses and industrial wiring applications requiring a protective heat shrink covering.

Reliable Cable Insulation and Identification for Industrial Electrical Systems

Heat shrink tubing provides a convenient method of insulating and protecting electrical cables by contracting around conductors and components when heat is applied. The Partex HS21016RED features a nominal 2:1 shrink ratio, allowing the tubing to reduce from approximately 101.6 mm to 50.8 mm in diameter when fully recovered. This makes it suitable for covering appropriately sized cable joints, large wiring assemblies and electrical terminations.

The red finish is particularly useful in industrial automation systems, electrical control panels and equipment wiring where colour coding helps maintenance personnel identify designated cables and circuits. The tubing can help protect cable insulation and connection areas while supporting organised cable management. Its large nominal diameter makes it suitable for substantial cable bundles and conductor assemblies. Red identification should be used in accordance with the applicable electrical wiring standards and site-specific identification requirements. For best results, the tubing should be selected according to the dimensions of the cable or component and installed using a suitable controlled heat source.

Typical Applications

• Electrical cable insulation and connection protection.
• Industrial control panel wiring and cable management.
• Colour-coded cable and conductor identification.
• Large cable joints and electrical termination coverings.
• Wire harness assembly and cable bundling.
• Industrial machinery and automation wiring.
• Electrical distribution and switchgear assemblies.
• Electrical maintenance, repair and installation work.
