MTJSWXSY Automotive Wire Loom – High-Temp Braided Split-Sleeve, 20ft x 1/8in

Overview

Meet MTJSWXSY’s automotive wire loom, a rugged protective sleeve designed to tidy and guard wiring harnesses in demanding vehicle environments. Crafted with a heat-retardant woven material, this black split-sleeve wrap supports organized, accessible cabling while resisting the stresses of under-hood use.

Engineered for heat and wear

The loom uses a heat-retardant woven PET polyethylene construction, delivering reliable performance even where wires face elevated temperatures. It tolerates temperatures up to 302 °F, helping maintain cable integrity and prolong the life of electrical runs in hot engine bays and high-load electrical circuits.

In addition to heat tolerance, the tightly woven fabric provides abrasion resistance. The protective sleeve helps shield cables from grime, mud, and mechanical wear, while still allowing drainage to prevent water buildup in crowded wiring paths. This makes it well suited for intricate harness routes where cleanliness and protection are essential.

Secure, flexible protection

The loom features a self-closing wrap-around design with a 25% overlap, delivering extended coverage without the need for extra tape, zippers, or fasteners. The overlapping braid helps prevent the wrap from loosening or twisting, while preserving flexibility for bends and turns along the harness.

Easy installation and maintenance

Designed with a side-entry opening, this heat-resistant loom installs smoothly on assembled bundles. It supports breakouts at any point, enabling quick adjustments, additions, or removals without dismantling nearby components. This user-friendly approach is ideal for ongoing wiring projects or future upgrades.

Real-world uses and possibilities

This rugged sleeve is well-suited to aftermarket builds, performance restorations, and off-road or industrial settings where heat, vibration, and space constraints are factors. While it does not promise guarantees, the loom aims to keep harnesses neater and more serviceable, potentially reducing maintenance time and helping you stay organized during upgrades.

Warranty and support

MTJSWXSY backs this product with a one-year warranty. If any issue arises, a replacement can be arranged through support within the warranty period.
