18 Gauge Primary Wire - 500 Feet

Primary wire is commonly considered the go-to wire type for all types of electrical applications. Our 18 gauge wire is manufactured with single copper conductor wire that his housed in a protective polyvinyl chloride (PVC) insulation. This design allows the 18 gauge wire to provide protection against grease, oil, and acids with added strength and durability. The primary wire’s PVC insulation features a smooth surface for ease of use in your application. 18 gauge wire can be ideal for both custom projects and replacements on existing applications. Del City offers our primary 18 gauge wire in a variety of spool sizes and colors to meet the specific needs of your application.
