18 Gauge Primary Wire - 100 to 6,000 Foot Spools

Primary wire, or AWG wire, is commonly used in automotive, marine, industrial, and general electrical applications. 18 gauge wire is manufactured with a single copper conductor wire and polyvinyl chloride (PVC) insulation. This construction allows the 18 gauge wire to provide added strength while being highly resistant to grease, oil, and acids. The primary wire PVC insulation features a smooth surface making it easy to work with. 18 gauge wire can be ideal for both custom projects and replacement needs on existing applications. Del City offers 18 gauge primary wire in a variety of spool sizes and colors to meet the needs of your application.
