Durable 18/4 x 1000 ft irrigation control cable designed for buried low-voltage valve circuits and controller connections. Built for contractors and homeowners who need a long, reliable spool for multi-zone irrigation systems.

  • 18 AWG, 4 conductors: Compact, multi-conductor design for common irrigation and low-voltage control applications.
  • PVC insulation: Individual conductor insulation helps protect against moisture and abrasion.
  • Polyethylene outer jacket with nylon ripcord: Tough outer layer resists soil abrasion; ripcord speeds jacket removal during installation.
  • Listed for direct burial: Suitable for underground installation without separate conduit when installed to local code.
  • 1000 ft spool: Long-length reel reduces joins and splice points on large runs.
  • Low-energy circuit cable: Engineered for valve solenoids, controllers and other irrigation control devices.

Use waterproof connectors or approved splice methods and follow local electrical and irrigation codes when burying. Keep runs free from sharp rocks and high-heat sources; protect connections with sealed junction boxes or approved wire nuts and tape. For best results, plan runs to minimize unnecessary splices and label conductor terminations at both ends of the spool.
