>> Product Introduction
Polyester self-rolling textile sleeve is made of polyester monofilament and multifilament yarns, featuring a quarter-inch overlap that provides excellent flame retardancy, wear resistance, and heat dissipation. These sleeves are designed to wrap around plugs, connectors, and joints and can easily be folded and bent thanks to their inherent elasticity. Their open-ended design allows for easy addition or removal of wires without disassembly, facilitating modifications, reinstallation, maintenance, and inspection of the inner wiring harness.
>> Product Advantage

>> Application Scenarios
● Automotive industry: protection for irregular‑shaped vehicle internal wire harness
● High‑speed rail & rail transit: rolling‑stock instrument and cable harness wrapping
● Communication equipment: wiring harness maintenance‑friendly cable protection
● Industrial automation equipment: flexible cable and instrument cable bundling & protection
● Flat wire harness & flexible tubing protection for machinery equipment
>> Selection Guide
● Measure the maximum outer diameter of bundled wire harness, select the sleeve nominal outer diameter slightly larger than harness OD for good self‑closing wrapping effect.
● Confirm working ambient temperature shall be kept within‑40℃ ~150℃.
● Choose hot‑knife cutting for clean‑cut ends when cutting to avoid fraying.
● Black & orange in stock; custom colors, sizes and printing available for large‑quantity orders.
>> FAQ
Q: What is the main advantage of self‑wrapping split braided sleeving?
A: Self‑closing split‑open structure, you can add or remove wires without disconnecting finished cables, ideal for harness modification and maintenance.
