Dependable 18/7 irrigation control wire designed for professional sprinkler and landscape systems. Each 500 ft roll contains seven 18 AWG solid copper conductors insulated with PVC and cabled beneath a durable polyethylene (PE) jacket for outdoor and underground installations.

  • Seven conductors, 18 AWG: Color-coded conductors provide a common plus six zone wires—ideal for multi-valve systems and controller connections.
  • Durable construction: Solid copper conductors with PVC insulation and PE outer jacket resist moisture, UV exposure, and abrasion in valve boxes and direct-burial applications.
  • Direct-burial rated: Built for below-grade runs and wet locations; suitable for low-voltage (30V) irrigation control circuits.
  • 500 ft roll: Long spool reduces splices and speeds installation on medium-to-large landscapes.
  • Easy identification: Color-coded insulation and footage markings help speed terminations and troubleshooting.

Compatible with standard irrigation controllers and solenoid valves, this 18/7 spool is a reliable choice for contractors and homeowners who need a sturdy, weather-resistant control cable for valves, controllers, and field wiring.
