Self-Rolling PET Braided Sleeve 38 mm Black, 25 m Spool — EFB Elektronik 801612.1

Self-Rolling PET Braided Sleeve 38 mm Black on a 25 m spool by EFB Elektronik is a flexible cable protection and organization solution for electrical and electronic installations. The sleeve is made from polyethylene terephthalate (PET) braided material that combines abrasion resistance with flexibility and air permeability, enabling neat routing of cable bundles in confined spaces. The self-rolling construction allows quick deployment without additional tools, and the black finish provides a discreet appearance suitable for visible and hidden installations.

Advantages

The PET braided sleeve offers mechanical protection against abrasion and minor impacts while remaining lightweight and bendable. Its self-rolling design speeds up installation: cut to length and let the sleeve expand over the cable bundle. The textile braid permits ventilation around cables, helping to reduce heat build-up. The black color masks wiring for a uniform look and is compatible with a wide range of environments including consumer electronics, industrial cabinets, and vehicle interiors.

Suitable for

• Cable management in desktop PCs and server racks
• Bundling wiring looms in automotive and marine applications
• Organizing harnesses inside industrial control panels and machinery
• Retrofit and repair jobs where quick sleeving of existing cables is needed

When it may not be suitable

This PET braided sleeve provides abrasion resistance and airflow but is not flameproof or rated for direct exposure to high temperatures beyond typical operating ranges of electronic equipment. It is not an electrical insulator replacement for items requiring specific dielectric properties or high-voltage clearances. For situations demanding continuous exposure to oils, aggressive chemicals, or extreme heat, consider materials specifically rated for those conditions.

Key specifications

• Material: braided polyethylene terephthalate (PET)
• Nominal expanded diameter: 38 mm
• Length per spool: 25 m
• Color: black
• Construction: self-rolling (expandable braid)
• Primary properties: abrasion resistant, flexible, breathable

How to use

Measure the length of cable to be protected and cut the required length from the 25 m spool. Compress the braided sleeve and position one end at the start of the cable bundle; the sleeve will expand to accommodate the cables as you slide it along. For fixed terminations, trim edges cleanly and secure with heat-shrink tubing, cable ties, or adhesive tape to prevent fraying. For routing through tight openings, fold the sleeve longitudinally to reduce its profile, insert the cables, then allow it to self-roll around the bundle.

What to consider before purchase

• Confirm that the 38 mm expanded diameter matches the combined diameter of your cable bundle.
• Decide if a self-rolling braid is appropriate for retrofitting existing harnesses versus pre-assembly.
• Evaluate environmental conditions such as temperature, chemical exposure, and flame requirements to ensure PET is suitable.
• Plan for end termination method (ties, heat-shrink, tape) to prevent fraying.

Usage recommendations

For clean installations, cut with sharp scissors and finish ends immediately using heat-shrink or binding. When bundling multiple cables, route larger conductors first and slide the braid over the bundle to minimize strain. Store the spool flat in a dry place to prevent deformation and ensure smooth dispensing during installation.
