SKU: SMA-141-185F Primary Wire Green 18 Gauge - 30 Foot Coil for Tractor and Equipment Wiring

When you're tracing down electrical gremlins or adding new accessories to your tractor, having the right wire makes all the difference. This 18-gauge green primary wire gives you 30 feet of reliable, flexible wiring that's built to handle the demanding conditions of farm equipment. Whether you're wiring up new work lights, fixing a faulty connection, or adding equipment to your setup, this wire gets the job done right.

What You're Getting

• Stranded copper construction that stays flexible even in cold weather and won't crack from vibration
• Thermoplastic insulation rated for 176°F that resists grease, oil, and acids common around farm equipment
• Bright green color coding makes circuit identification easy when you're troubleshooting later
• Smooth surface that pulls easily through conduit or protective tubing
• Meets S.A.E. J1128 specifications for automotive and equipment use

Built for Real Farm Work

This is the same type of basic wire used for autos, trucks and numerous other wiring projects, making it perfect for tractors, combines, implements, and other farm equipment. The 18-gauge size handles most accessory circuits like lights, gauges, and control switches without being bulky or hard to work with in tight spaces.

Made to Last

Farm equipment wiring takes a beating from heat, cold, moisture, and constant vibration. This wire's thermoplastic insulation is engineered to stand up to temperature extremes while the stranded copper core stays flexible and conductive season after season. It's resistant to the oils, hydraulic fluid, and chemicals you'll encounter around equipment.

Good to Know

At 30 feet, this coil gives you enough length for most wiring jobs without waste. The green color is perfect for ground circuits or any application where you want consistent color coding. Keep the wire protected from sharp edges and moving parts, and always use proper gauge wire for your electrical load—18-gauge is great for low-amperage accessories but step up to heavier wire for high-draw equipment.
