Primary wire is commonly used in automotive, marine, industrial, and general electrical applications. 18 gauge wire features a single copper conductor wire and polyvinyl chloride (PVC) insulation. This construction provides added strength to the 18 gauge wire, while making it highly resistant to grease, oil, and acids. Primary wire features a smooth surface which makes it easy to work with and simple to pull through conduit. Ideal for both original projects and replacement needs, 18 gauge wire is available in a variety of spool sizes and colors to meet the demands of your unique project or application.
