MTJSWXSY Automotive Braided Split Wire Loom 3/4" 16ft

MTJSWXSY Automotive Wire Loom is a 16ft, 3/4-inch braided split sleeve that protects wiring from heat, abrasion, and wear while allowing fast side-entry installation.

This braided split-sleeve is designed for automotive harnesses, marine wiring, motorsports, and any application where cables face high temperatures and mechanical wear. Made from a heat-retardant woven PET material, the loom balances flexibility and toughness so you can route, protect, and service bundles without tearing or adding bulky tape. The design includes a self-closing overlap that secures cables while permitting easy breakouts and modifications.

How hot can this wire loom handle?

The MTJSWXSY split-sleeve is engineered to resist elevated temperatures, safeguarding wires in engine bays and other hot zones. The braided PET weave helps spread heat along the sleeve and away from concentrated points.

• Rated heat resistance up to 302°F (150°C).
• Heat-dispersing braided construction reduces hotspots.
• Suitable for near-engine, exhaust-adjacent, and high-current areas.

Will it protect wiring from abrasion and dirt?

The tightly woven, abrasion-resistant construction blocks scuffs, road debris, and contaminants while allowing moisture to drain rather than collect. That makes it practical for underbody harnesses, ATV rigs, and exposed cable runs.

• Durable woven PET resists wear from vibration and rubbing.
• Design prevents mud and grime accumulation and drains moisture.
• Maintains flexibility for tight bends and complex routing.

How easy is installation and service with the split design?

The side-entry split lets you apply the sleeve to already-assembled wiring bundles without disconnecting connectors. A self-wrapping overlap secures the braid, eliminating the need for extra tape or zippers and simplifying future changes.

• Split-sleeve side access enables retrofit over existing harnesses.
• Approximately 25% overlap keeps the braid closed under movement.
• Quick access for cable breakouts, repairs, or additions along the run.

What sizes and practical features does this product include?

This listing is for a 16-foot length with a 3/4-inch internal diameter, a common size for engine bay harnesses and grouped wire runs. The material and overlap ratio were chosen to balance coverage, flexibility, and secure containment.

• Length: 16 feet — ample for multiple harness routes or repairs.
• Diameter: 3/4 inch — fits many multi-conductor bundles and grouped cables.
• Self-closing braided mesh with 25% overlap prevents unraveling.

Who is this product for? Technicians, DIYers, and fleet maintenance staff who need a resilient, heat-tolerant solution for protecting wiring will find this braided split loom valuable. It’s well suited to automotive restorations, performance builds, marine installations, industrial machinery, and any situation where wiring must be bundled, shielded, and regularly accessed. Backed by a one-year warranty, MTJSWXSY provides a practical, service-friendly cable management sleeve for demanding environments.
