When you’re fixing a broken wire on your tractor or rigging up new work lights, you need wire that’s going to hold up to the job. This 18-gauge primary wire gives you the flexibility to handle lighter electrical loads like instrument panels, warning lights, and accessory circuits without the bulk of heavier gauge wire.
What You’re Getting
- 18 AWG stranded copper wire that’s easy to work with and route through tight spaces
- Bright red insulation makes it simple to trace circuits and follow wiring diagrams
- Thermoplastic insulation that stays flexible in cold weather and won’t crack in the heat
- Oil, grease, and acid resistant coating that handles whatever the farm throws at it
- 30-foot coil gives you plenty to complete most repair jobs with some left over
Built for Real Farm Work
This wire is perfect for tractors, combines, balers, and other farm equipment where you need reliable connections for lighter electrical loads. Whether you’re replacing damaged harness wires, adding new gauges to your cab, or wiring up work lights, this wire handles the voltage without being overkill for the application.
Made to Last
The smooth surface makes it easy to pull through existing looms and conduit, while the durable insulation resists the oils, fuels, and chemicals you’ll find around farm equipment. It’s built to handle the vibration and temperature swings that come with outdoor work.
Good to Know
18-gauge wire is ideal for circuits drawing up to about 16 amps, making it perfect for most accessory and instrument applications. The stranded copper core is much easier to work with than solid wire when you’re making connections in tight spaces. Always use proper connectors and heat shrink tubing for connections that’ll last.
