18/3 x 500 ft irrigation control wire engineered for low‑voltage sprinkler and irrigation systems. This 18 AWG, three‑conductor cable combines durable PVC insulation and an extruded polyethylene (PE) outer jacket with a nylon rip cord so you can install and splice quickly and confidently. It’s designed for direct burial and outdoor use where long runs between the controller and valves are required.

  • Three color‑coded 18 AWG conductors for easy identification and consistent performance.
  • PVC insulation protects each conductor and withstands typical burial and valve box conditions.
  • Extruded PE outer jacket resists sunlight and moisture; integrated nylon rip cord speeds cable access.
  • Suitable for low‑voltage irrigation circuits (typical controller outputs such as 24 V); ideal for valve control wiring.
  • 500 ft spool reduces the need for splices on large residential or commercial sites.
  • Listed for direct burial and intended for underground low‑energy circuit applications.

Use this multi‑conductor spool when you need a reliable, easy‑to‑install connection between your irrigation controller and remote solenoid valves. Follow local code and manufacturer recommendations for splicing and protection in valve boxes; for best results use weatherproof connectors and maintain proper separation from high‑voltage cables. Store the spool in a cool, dry place prior to installation and avoid sharp bends to preserve conductor integrity.

Frequently Asked Questions

What voltage is this irrigation wire rated for?
This 18/3 cable is intended for low‑voltage irrigation control circuits (typical controller outputs such as 24 V) and is listed for direct burial.
Can I bury this wire directly without conduit?
Yes—the cable is listed for direct burial with a PE jacket, but follow local code for depth and use conduit where required or for added protection.
How should I splice and protect irrigation wire connections?
Use weatherproof wire connectors or manufacturer‑recommended splicing kits in a valve box; avoid exposed joints and keep good separation from high‑voltage wiring.
