Why Choose the Partex SUP20BLACK Supaflex Braided Sleeving?

The Partex SUP20BLACK Supaflex Braided Sleeving is a flexible, expandable cable protection solution designed to organise, bundle and protect electrical cables, wiring harnesses and industrial cable assemblies. Part of the Partex Supaflex range, this black braided sleeving provides a practical solution for professional cable management in electrical installations, industrial machinery, automation systems and equipment manufacturing.

Designed to accommodate cable bundles within a 15–27 mm diameter range, the SUP20BLACK features an expandable braided construction that adapts to different cable bundle sizes. Its flexible design allows the sleeving to follow bends and curved cable routes, helping maintain organised wiring while providing supplementary protection against rubbing and abrasion.

The black finish provides a discreet, professional appearance suitable for industrial control cabinets, machinery and electrical equipment. With its larger expandable diameter range, the Partex SUP20BLACK is particularly useful for grouping multiple cables into a single organised assembly, improving cable routing and providing additional mechanical protection in demanding installations.

Flexible Cable Protection for Larger Wiring Harnesses and Cable Bundles

The Partex SUP20BLACK Supaflex braided sleeving provides an adaptable protective covering for electrical cables and wiring assemblies. Unlike rigid conduit or fixed-diameter tubing, expandable braided sleeving adjusts to different cable bundle sizes, making it useful where wiring configurations vary or multiple cables need to be grouped together.

With a suitable diameter range of 15–27 mm, the SUP20BLACK is particularly useful for medium to large wiring harnesses, industrial control cables, machinery wiring and equipment assemblies. Its flexible braided structure allows the sleeving to follow cable routes around bends while maintaining coverage over the enclosed bundle.

The black braided finish provides a clean and consistent appearance for control panels, machinery and electrical equipment. It is especially useful for installations where multiple individual cables need to be grouped into a manageable wiring loom, helping simplify cable routing and improve the overall presentation of the installation.

The braided construction helps minimise direct rubbing between enclosed cables and adjacent surfaces, providing supplementary abrasion protection in equipment cabinets, machinery and industrial installations. Its expandable design makes it suitable for cable assemblies requiring flexible routing rather than rigid containment.

For installation, select the correct sleeve diameter, cut the required length and fit the sleeving over the cable bundle. Because expandable braided sleeving can shorten as its diameter increases, installers should allow sufficient material to maintain the required coverage. Cut ends should be finished using a method compatible with the sleeving material to help prevent fraying.

The SUP20BLACK is intended as a cable management and protective sleeving accessory rather than a substitute for primary cable insulation, protective conduit or certified fire protection. Suitability for specific temperatures, chemicals, UV exposure and flame-retardancy requirements should be checked against the applicable manufacturer specifications.

Typical Applications

  • Medium to large electrical cable bundling and organisation.
  • Industrial machinery wiring harness protection.
  • Control panel and switchgear cable management.
  • Industrial automation and control system installations.
  • Electronic equipment and instrumentation cable assemblies.
  • OEM machinery and equipment manufacturing.
  • Production line wiring and cable routing.
  • Building services and electrical engineering installations.
  • Maintenance and refurbishment of industrial electrical equipment.
  • Applications requiring flexible black braided sleeving for 15–27 mm cable bundles.
