PET (Polyethylene Terephthalate) Braided Sleeving is a lightweight, high-performance wire harness protection sleeve precision-braided from PET monofilament or multifilament yarns. It provides superior abrasion protection, extreme flexibility, flame retardancy, and excellent thermal dissipation.
1. Product Overview & Key Specifications
Technical Feature | Description & Parameters |
Material | Polyethylene Terephthalate (PET Monofilament / Multifilament) |
Operating Temp. Range | -50°C to +150°C (Melting Point: 240°C ± 10°C) |

Certifications | RoHS, REACH, Halogen-Free, ISO 9001, ISO 14001, EN 45545-2 |
Key Advantages | 1. High Expandability: Expands 150%–300% to fit easily over large plugs & connectors. 2. Abrasion & Chemical Resistance: Shields against wear, friction, oils, and UV exposure. 3. Open-Mesh Design: Lightweight, breathable (prevents heat buildup), and highly flexible. |
Structure Options | Closed Expandable Braided Sleeving, Split Self-Wrapping Sleeving (for retrofitting). |
2. Primary Application Scenarios
• Automotive & EV Industry: Engine bay harnesses, high-voltage battery cables, charging infrastructure, and turbocharger tubing proximity protection.
• Industrial Automation & Robotics: Cable drag chains, dynamic robotic arms, and automated equipment requiring frequent movement and wear resistance.
• Railway & Transit: Flame-retardant and low-smoke cable bundling inside train control cabinets, railcars, and aerospace transit equipment.
• Telecom & Data Centers: Server rack cable management, patch cord bundling, and fiber optic cable protection.
• Home Electronics & Audio/Visual: Desktop PC cable organizing, high-end audio wiring protection, and pet-chew prevention.
3. Step-by-Step Installation Guide
1 Measurement & Sizing Selection:
◦ Measure the maximum outer diameter (OD) of your wire harness including connectors.
◦ Note: Braided sleeving shortens lengthwise by approximately 20%–30% when expanded. Always cut the sleeving slightly longer than the cable length.
2 Hot Cutting (Fraying Prevention):
◦ PET monofilaments will fray if cut with standard scissors.
◦ Use a Hot Knife Cutter to melt and seal the ends simultaneously. If using standard shears, singe the cut edge lightly with a heat gun or lighter to seal the strands.
3 Accordion Push-and-Feed Method:
◦ Compress the sleeving lengthwise to expand its inner diameter, then push the wire harness through.
◦ Once positioned, smooth and pull the sleeving taut along the bundle for a snug fit.
4 End Termination & Fixing:
◦ Secure both open ends to prevent retraction or slipping.
◦ Use adhesive-lined heat shrink tubing, cable ties, or electrical tape to firmly clamp the ends to the main cable jacket.
