Reliable 18/5 x 500 ft irrigation control wire for sprinkler and irrigation systems. This multi-conductor cable provides five separate 18 AWG conductors on a convenient 500 foot spool for routing between controllers and valve solenoids.

  • 500 ft spool reduces joins and speeds installation over long runs.
  • Five 18 AWG conductors supply individual valve circuits to standard irrigation controllers.
  • Flexible jacket and stranded conductors allow easier routing through trenches and conduit.
  • Color-coded conductors simplify wiring and reduce installation errors.
  • Designed for low-voltage control use with solenoids, timers, and zone controllers.

Keep a spool on hand for repairs, new installations, or expansion projects. If you need help selecting the right gauge or routing method, contact our technical support before installing to ensure compatibility with your controller and local codes.

Frequently Asked Questions

What devices is 18/5 control wire compatible with?
Works with most low-voltage irrigation controllers and solenoid valves; confirm terminal requirements before installation.
Can I run 18/5 wire in conduit or underground?
Yes. Route through conduit or direct-bury with protection where required by code; follow local burial depth and conduit rules.
How many valves can I run on one 5-conductor cable?
One conductor per valve plus a shared commonā€”an 18/5 cable typically supports four valves plus the common conductor.
What length considerations should I keep in mind for voltage drop?
Long runs can cause voltage drop and affect solenoid performance; keep runs short or consult controller specs or use larger gauge for long distances.
