WireGarage GXL 18 AWG Stranded Wire — 12 Solid Colors, 10 ft Each, XLPE High-Temp Automotive

WireGarage GXL 18 AWG stranded wire is a high-temperature, cross-linked polyethylene (XLPE) insulated automotive wire supplied in twelve solid colors, 10 feet each (120 feet total).

This automotive-grade GXL wire is made for electrical systems that need durable, heat-resistant conductors. The smooth XLPE jacket resists abrasion, oil, gasoline, solvents and moisture, and the stranded copper core makes the wire flexible for routing in tight engine bays, motorcycles, boats or custom electrical projects. The bundle contains twelve distinct solid colors to simplify circuit identification and meets SAE J1128 practices for automotive wire construction.

What environments is this GXL wire rated for?

The insulation is chemically cross-linked polyethylene, which preserves flexibility while holding up to elevated temperatures and common automotive contaminants. Use it where heat, oil and abrasion are concerns but avoid applications outside the listed temperature range.

• Temperature range: -40°C (-40°F) to 125°C (257°F)
• Resistant to gasoline, oil, solvents, grease and most acids
• Designed for engine compartments, motorcycle harnesses and similar areas
• Meets SAE J1128 wiring construction expectations

How does the 18 AWG stranded conductor perform in installations?

Stranded copper in 18 AWG offers a balance of current capacity and flexibility, making it easier to route through connectors and around bends than solid wire. It reduces the risk of fatigue from vibration and repeated movement in automotive or motorcycle applications.

• Stranded copper conductor for improved flexibility
• Simplifies routing in tight spaces and around components
• Better resistance to vibration-induced breakage than solid wire
• Compatible with common 18 AWG terminals and crimp connectors

How will the 12-color pack help with wiring projects?

Having twelve distinct solid colors in 10-foot lengths streamlines identification, reduces wiring errors and speeds troubleshooting. The colors are intended for straightforward color-coding of circuits in harnesses, panels or custom builds.

• 12 solid colors—10 feet per color, 120 feet total per pack
• Color coding simplifies circuit mapping and repairs
• Suitable for building harnesses, splices and multi-run bundles
• Colors may vary slightly by package batch

Can I use this wire for non-automotive electrical work?

Yes — the characteristics that make this wire suitable for vehicles also benefit many other applications that require heat and chemical resistance. Always confirm that temperature, voltage and local electrical codes are met before using it in stationary or building wiring.

• Appropriate for marine, powersports and industrial control wiring with similar conditions
• Check voltage ratings and code compliance for household or permanent building circuits
• Useful for prototyping, custom harnesses and equipment repairs
• Keep wire away from sharp edges and use proper grommets where needed

Who is this for: Technicians, hobbyists and DIY mechanics who need flexible, high-temperature automotive wire for engine compartments, motorcycles, boats and custom electrical work. If you build harnesses, retrofit components or maintain vehicles and small equipment, this 18 AWG GXL pack gives you a range of colors and the chemical and temperature resistance expected for harsh-duty environments.
