MTJSWXSY Braided Wire Loom 1/4" Heat-Resistant Split Sleeve

MTJSWXSY Automotive Wire Loom is a 20-foot, 1/4" braided split-sleeve made from heat-retardant PET that protects wiring up to 302°F while self-wrapping for tool-free installation.

This heavy-duty black braided wire loom is engineered to protect, organize, and extend the life of harness wires in vehicles, marine craft, industrial machines, and home projects. The woven PET construction combines abrasion resistance with heat dispersion, and the split, side-entry design lets you install or modify existing cable bundles without disconnecting components. With a 25% overlap for secure coverage and a one-year warranty, it’s built for demanding environments where heat and wear are concerns.

How does this wire loom handle high temperatures?

The MTJSWXSY braided sleeve is manufactured from heat-retardant PET that tolerates continuous exposure and dissipates heat instead of trapping it. That reduces thermal stress on insulation and connectors, making it suitable near engines, exhausts, and other hot zones.

• Rated for heat resistance up to 302°F (150°C).
• Open braided weave encourages heat dispersion, not insulation.
• Protects insulation from heat-related degradation and short-term spikes.

Will it stand up to abrasion, fluids, and road debris?

The woven encryption design delivers durable abrasion resistance and sheds dirt and moisture thanks to its tight but draining weave. It’s meant to protect harnesses from chafing against metal, vibration points, and environmental grime encountered under hoods or beneath vehicles.

• Tightly woven, abrasion-resistant PET fibers resist wear from rubbing and vibration.
• Weave allows drainage to prevent water trapping and mud buildup.
• Ideal for routing along frame rails, engine bays, or exposed wheel wells.

How easy is installation and maintenance with the split/sleeve design?

The split, self-wrapping construction plus side-entry design means you can apply the sleeve around an assembled bundle without disassembling connectors. The 25% overlap keeps the braid closed and prevents twisting, while allowing quick breakouts or additions wherever needed.

• Side-opening split lets you wrap existing harnesses in-place.
• Self-closing braid with 25% overlap reduces need for tape or clamps.
• Cut-to-length flexibility for custom installations; add or remove wires easily.

What length, diameter, and warranty details should I know before buying?

This listing supplies a 20-foot (approx. 6.1 m) length of 1/4-inch (about 6 mm) internal diameter braided loom—useful for multiple runs or longer harness protection. MTJSWXSY backs the product with a one-year warranty covering defects, with replacement or refund policies to simplify after-sale support.

• Length: 20 feet; Diameter: 1/4 inch (6 mm) interior approximate.
• Color: black for low-visibility, OEM-friendly routing.
• One-year warranty: refund and replacement option if issues arise.

Who is this for? Technicians, hobbyists, fabricators, and vehicle owners who need a compact, heat-resistant, and abrasion-proof solution for wiring harnesses will find this sleeve practical. It’s suited to automotive and marine repair, custom wiring projects, vintage restorations, engine-bay routing, and industrial control panels where space is tight and heat exposure is common. Choose this braided split-sleeve when you need reliable protection, easy retrofitting, and a tidy, low-profile finish for critical wiring runs.
