HSMB254BLACK Partex 2:1 heat shrink tubing, 25.4/12.7mm, black, pack 5m

Why Choose the Partex HSMB254BLACK 2:1 Black Heat Shrink Tubing?

The Partex HSMB254BLACK is a versatile and reliable black heat shrink tubing designed for electrical insulation, cable identification and protection of wires and electrical connections. Featuring a 2:1 shrink ratio, this tubing contracts when heated to provide a neat, close-fitting protective covering around compatible cables, conductors and electrical components.

As part of the Partex HSMB heat shrink tubing range, it provides a practical solution for electrical installers, maintenance engineers and control panel builders requiring effective cable protection and insulation. Its black colour provides a discreet, professional finish for electrical wiring assemblies, while its heat-activated shrinking action enables a close-fitting protective sleeve around appropriately sized cables and connections.

With a nominal supplied diameter of 25.4 mm, a recovered diameter of 12.7 mm and a 5 m pack length, the HSMB254BLACK is suitable for insulating and protecting larger cables, cable bundles and electrical connections in industrial machinery, electrical control panels and general wiring applications.

Key Advantages

• 2:1 heat shrink ratio provides a close-fitting protective sleeve around compatible cables and electrical connections.
• 25.4 mm nominal supplied diameter accommodates larger cables and appropriately sized wiring assemblies.

Reliable Cable Insulation and Protection for Industrial Electrical Systems

Heat shrink tubing is widely used in electrical engineering to provide insulation, protect conductors and improve the organisation of cable assemblies. When suitable heat is applied, the tubing contracts around the underlying cable or component, creating a close-fitting sleeve that helps reduce exposure to abrasion and everyday handling damage.

The Partex HSMB254BLACK is designed for applications where black cable insulation and heat shrink protection are required. Its 2:1 shrink ratio makes it suitable for appropriately sized cables and electrical connections, while the convenient 5 m pack allows electrical engineers and installers to cut the tubing to the required length for each installation. The larger nominal supplied diameter makes it particularly useful for cable bundles, larger conductors and electrical wiring assemblies where smaller heat shrink tubing would not provide sufficient clearance before shrinking.

Typical Applications

• Electrical cable insulation and wire protection.
• Control panel wiring and electrical cabinet assembly.
• Industrial machinery and automation wiring.
• Protection and identification of larger cables and cable bundles.
• Insulation of compatible cable joints and electrical terminations.
• Electrical maintenance, servicing and repair applications.
• OEM equipment manufacturing and cable harness assembly.
