HS21016GREY Partex 2:1 heat shrink tubing, 101.6/50.8mm, grey, pack 15m

Why Choose the Partex HS21016GREY Heat Shrink Tubing?

The Partex HS21016GREY is a versatile grey 2:1 heat shrink tubing designed for electrical insulation, cable identification and protective sleeving in industrial and commercial electrical installations. Supplied in a convenient 15 m pack, this tubing provides a practical solution for protecting large cables, wiring bundles and electrical components.

Featuring a nominal supplied diameter of 101.6 mm and a nominal fully recovered diameter of 50.8 mm, the tubing contracts when suitable heat is applied, forming a close-fitting protective covering around compatible cables and assemblies. Its 2:1 shrink ratio allows the tubing to reduce to approximately half its original diameter, making it suitable for larger cable protection applications.

The distinctive grey colour supports visual identification and organised cable management in industrial wiring systems. As part of the Partex heat shrink tubing range, the HS21016GREY offers a practical solution for electrical contractors, panel builders, maintenance engineers and cable assembly specialists requiring protective sleeving and professional cable identification.

Reliable Protection for Large Electrical Cables and Assemblies

Heat shrink tubing provides a practical way to protect, insulate and organise electrical wiring. When suitable heat is applied, the tubing contracts around the underlying cable or component, creating a neat protective covering that helps reduce exposure to abrasion and general mechanical wear.

The Partex HS21016GREY is particularly useful for larger cable assemblies requiring a wide initial opening. Its 101.6 mm supplied diameter allows installation over suitably sized cables and components, while its 2:1 shrink ratio provides a nominal fully recovered diameter of 50.8 mm. The grey finish also supports clear visual identification within cable management systems.

For professional installations, the tubing should be selected according to the cable diameter, required insulation properties and operating environment. Grey is also recognised as a line conductor identification colour in applicable UK and European wiring conventions, although its use must comply with the identification requirements of the particular installation.

Typical Applications

• Large electrical cable insulation and protective sleeving.
• Industrial cable bundles and wiring harnesses.
• Grey colour-coded cable and conductor identification.
• Electrical control panels and distribution equipment.
• Protective covering for compatible cable joints and connections.
• Industrial machinery wiring and electrical maintenance.
• Cable assembly, preparation and general installation work.
