Advantages
Braided Self-Wrapping Sleeving provides fast installation, excellent abrasion protection and a clean, professional wiring finish. It is perfect for OEM harness makers, automotive manufacturers, electrical panel builders and industrial machinery wiring.

Textile Sleeve is a flexible, lightweight protective sleeving made from woven or braided textile fibers such as polyester, nylon, cotton, or blended technical yarns. It is designed to offer excellent abrasion resistance, vibration protection, cable bundling support and mechanical protection for wires, hoses, conduits and harnesses in automotive, electrical, industrial and machinery applications.

The woven or braided structure allows the sleeve to expand and contract, making installation easy even over connectors, joints or irregular cable shapes. Textile Sleeves offer superior flexibility and are ideal for cable routing, harness wrapping, noise-dampening, anti-scratch protection and surface protection in dynamic environments.

These sleeves are preferred for wiring harnesses, automotive dashboards, interior cable looms, EV wiring bundles, robotics, CNC machines, household appliances, control panels and consumer electronics. Textile Sleeves are also used as an aesthetic solution because of their clean, soft and professional finish.
