    Description

    Whether you're rewiring lights on your cab, fixing a connection in the dash, or running new circuits for implements, having quality primary wire on hand saves you time and headaches. This 18-gauge white wire is perfect for low-current applications where you need reliable connections that won't let you down when you're miles from the shop.

    What You're Getting

    • Stranded copper core that stays flexible even in cold weather
    • GPT thermoplastic insulation rated for 176°F - handles engine bay heat without cracking
    • Smooth surface coating makes it easy to pull through conduit and wire looms
    • 30-foot length gives you plenty to complete most jobs with some left over for the toolbox
    • Bright white insulation for easy circuit identification and troubleshooting

    Built for Real Farm Work

    This wire meets SAE J1128 automotive specifications, so it's built tough enough for the vibration, temperature swings, and harsh conditions your tractor sees every day. From instrument panels to work lights, this is the same quality wire that OEMs use in their harnesses.

    Made to Last

    The copper conductor is properly annealed so it won't work-harden and break from flexing. The insulation is resistant to oil, grease, and acids - important when you're working around hydraulic fluid and diesel fuel. Made in the USA to professional standards.

    Good to Know

    18-gauge wire handles up to about 16 amps safely, making it ideal for most lighting circuits, sensors, and control switches. If you're not sure about current requirements, it's always better to go one size larger. Keep some electrical tape and butt connectors handy for clean, weatherproof connections.
