MTJSWXSY Braided Split-Sleeve Wire Loom 3/8" 16ft

MTJSWXSY Automotive Wire Loom is a 16-foot, 3/8-inch braided, split sleeve designed to protect and organize vehicle wiring with high-temperature resistance and self-wrapping convenience.

Built from heat-retardant woven PET polyethylene, this black braided wire loom is engineered for automotive and industrial harness protection where heat, abrasion, and tight routing are common. The split-sleeve design opens along its length so you can wrap it around existing cable bundles without disconnecting connectors. Its tightly woven construction sheds dirt and moisture while the braided structure helps disperse heat, extending the useful life of wires routed near hot engine components or tight spaces.

How hot can this braided wire loom handle?

The MTJSWXSY loom resists elevated temperatures thanks to its PET polyethylene weave and braided construction. It withstands continuous exposure up to 302°F (150°C) while allowing heat to dissipate along the braid, reducing hot spots around cables.

• Rated heat resistance up to 302°F (150°C)
• Braided weave promotes heat dispersion
• Suitable for close-proximity routing near engines and exhaust components
• Helps reduce thermal stress on cable insulation

Is it easy to install on existing harnesses?

Yes. The split-sleeve and side-entry design allow you to wrap the loom over assembled wiring without removing terminals or reconnecting harness plugs. The self-closing wrap reduces the need for additional tape or clamps for many installations.

• Side-entry split for fast retrofits and maintenance
• Self-wrapping action with 25% overlap for secure coverage
• Can be cut to length for custom runs and individual breakouts
• Permits cable add/removal without full disassembly

How does it protect cables from wear and environmental damage?

The dense woven construction offers abrasion resistance against wire chafing and shields bundles from dirt and debris. The braided sleeve also drains moisture while keeping contaminants away from delicate insulation, extending harness durability in demanding conditions.

• Abrasion-resistant woven material for long-term wear protection
• Tight weave design repels mud, grit, and road grime
• Drainage-friendly structure to avoid trapped water
• Maintains flexibility for routed, contoured harnesses

Will this loom stay closed and prevent unraveling?

The loom features a 25% overlap in the braid and a self-closing wrap that minimizes the need for extra fasteners. This overlap helps keep the sleeve aligned around bundles, reducing slippage and preventing the braid from twisting free under vibration.

• 25% overlap mesh for consistent, extended coverage
• Self-closing wrap reduces need for tape or zips
• Resists separation under vibration and flexing
• Easy to secure further with zip ties if desired

Who this is for: Automotive DIYers, mechanics, fabricators, and equipment technicians who need a compact, heat-resistant, and abrasion-proof sleeve for wiring harnesses. It’s ideal for engine bays, off-road vehicles, trailers, marine applications, and any project where existing cables must be protected without full disassembly. The 16-foot length and 3/8-inch diameter fit small to medium bundles and allow multiple runs or spare length for complex harness routing. MTJSWXSY includes a one-year warranty for replacement or refund if issues arise within the first year.
