Why Choose the Partex HS212BLACK 2:1 Black Heat Shrink Tubing?
The Partex HS212BLACK is a versatile 2:1 black heat shrink tubing designed for insulating, protecting and identifying small electrical wires, cable joints and electronic connections. Featuring a 1.2 mm nominal supplied diameter and a 0.6 mm nominal recovered diameter, this compact heat shrink sleeve provides a practical solution for applications requiring a neat, close-fitting protective covering around small conductors and components.
With a 2:1 shrink ratio, the HS212BLACK is designed to reduce to approximately half its original diameter when heated under suitable conditions. This allows the tubing to be positioned over a compatible wire or connection before shrinking to form a closely fitting sleeve. Its black finish provides a discreet, professional appearance and makes it particularly suitable for electrical wiring, electronic assemblies, control equipment and cable identification applications.
Supplied in a generous 150 m pack, the Partex HS212BLACK offers a convenient solution for electrical contractors, electronics manufacturers, maintenance engineers and OEM equipment builders requiring repeatable heat shrink protection across multiple installations. Its small diameter, straightforward heat application and continuous cut-to-length flexibility make it an effective choice for precision wiring and professional electrical assembly work.

Reliable 2:1 Heat Shrink Protection for Small Electrical Wires and Connections
Effective electrical insulation and cable finishing are important for maintaining organised, dependable wiring assemblies. The Partex HS212BLACK provides a convenient method of applying a closely fitting sleeve to compatible small conductors, wire joints and electronic connections. Once the tubing has been positioned and exposed to suitable heat, its diameter reduces around the underlying component, helping create a neat protective covering without the need for adhesive tape or separate fastening accessories.
The 1.2 mm to 0.6 mm nominal diameter range is particularly useful for precision wiring applications involving small conductors and electronic assemblies. The tubing should be selected so that its supplied diameter is large enough to pass over the intended component, while its recovered diameter is sufficiently small to achieve the required fit. The 2:1 shrink ratio provides a straightforward relationship between supplied and recovered dimensions, helping installers select suitable tubing for different wiring tasks.
For dependable results, the tubing should be cut cleanly, positioned over the intended wire or connection and heated evenly using appropriate equipment. Excessive or uneven heating should be avoided to prevent damage to the tubing or underlying cable insulation. The HS212BLACK should not be assumed to be adhesive-lined, waterproof, flame-retardant or suitable for a particular operating voltage or temperature without confirmation of the relevant manufacturer specification. For safety-critical electrical insulation, the complete installation must meet the applicable electrical requirements.
