MTJSWXSY 1" Automotive Braided Split Wire Loom 20ft

This heavy-duty braided wire loom is engineered for automotive and industrial wiring harnesses where elevated temperatures, abrasion, and tight routing demand durable protection. Made from heat-retardant woven PET, the sleeve resists temperatures up to 302°F and disperses heat across its braided construction. Its split, wrap-around design simplifies retrofits and maintenance—no disassembly of connectors required—while the 25% overlap prevents unraveling and keeps bundles tidy.

How does the loom resist high temperatures and reduce heat buildup?

The braided PET material is formulated for heat retardancy and spreads heat across the sleeve instead of letting it concentrate on a single point. This lowers thermal stress on individual wires and on the insulation over time without adding heavy insulation bulk. Use it where engine bays, exhaust routing, or other hot zones threaten cable longevity.

• Heat-retardant woven PET material rated to 302°F (150°C).
• Open braided construction for efficient heat dispersion.
• Lightweight compared to thick thermal wraps—adds minimal bulk.

Will this braided split sleeve stand up to abrasion, dirt, and moisture?

The precision-woven, abrasion-resistant braid shields harnesses from rubbing, road debris, and grime while permitting drainage so water won’t pool inside the sleeve. The tight weave prevents fraying and resists punctures from sharp edges. It’s a practical protective layer for under-hood wiring, chassis runs, and exposed connectors.

• Tightly woven pattern resists wear from vibration and rubbing.
• Drainage-friendly braid avoids trapped moisture.
• Works well around bends and tight routing paths without splitting.

How easy is it to install and maintain wiring with the split, self-wrapping design?

The split-sleeve profile opens for side-entry so you can wrap existing harnesses without disconnecting connectors. The 25% overlap of the braid keeps the wrap secure and reduces the need for extra tape or clamps. Add or remove wires at any point for quick maintenance and customization.

• Side-entry split allows retrofit over assembled harnesses.
• Self-closing wrap design keeps the sleeve in place without extras.
• Cut-to-length flexibility for custom runs and branch points.

What length, size, and warranty information should buyers know?

This listing includes a continuous 20-foot length of 1-inch diameter braided split sleeve suitable for most small-to-medium harness bundles. The material balances flexibility and coverage for neat routing through tight spaces. MTJSWXSY backs the product with a one-year warranty—defective items will be refunded and replaced without return hassles.

• Length: 20 feet continuous; Diameter: 1 inch (approx. 25 mm).
• Ideal for small-to-medium wire bundles and harness branch points.
• One-year warranty with refund and replacement policy.

Who is this for: Technicians, DIY automotive enthusiasts, and industrial maintenance teams who need a reliable, heat-resistant protective sleeve for wiring harnesses. If you retrofit harnesses often or route cables near hot components, this split, braided loom provides robust abrasion resistance, straightforward installation, and predictable thermal performance without bulky insulation.
