Orbit Underground Sprinkler Wire 7-Strand 100 ft 18-Gauge — UV-Resistant, Direct-Burial for 6 Valves

Orbit 7-strand, 100-foot 18-gauge underground sprinkler wire delivers color-coded, UV-resistant conductors to reliably carry 24 VAC from your controller to up to six valves.

Built for buried irrigation systems, this 7-conductor cable by Orbit combines durable 18-gauge copper cores with a UV-resistant PVC jacket so you can run zones, commons, and splices underground without frequent maintenance. The seven individually insulated strands include a white common and six color-coded wires for easy mapping to controller station terminals. Rated for direct burial, the cable tolerates moisture and freezing conditions commonly found in outdoor landscapes.

How do I use this wire with my sprinkler controller?

Connect each colored conductor to a separate station terminal on your controller and run the white wire to the controller’s common (C) terminal. Keep runs neat and labeled so future troubleshooting or expansion is straightforward. For splices, always use waterproof connectors or gel-filled splice kits to prevent corrosion at valve manifolds.

• Connect each colored strand to one valve station terminal.
• White strand serves as the common/ground returning to controller C terminal.
• Use waterproof wire nuts or heat-shrink gel connectors at splices and valves.
• Strip insulation with wire cutters; avoid nicking conductors.

What installation conditions is this wire designed for?

The Orbit cable is made for direct burial and outdoor irrigation use with cold water only. Its PVC jacket is UV-resistant and resists moisture and freeze-thaw cycles; still, keep wire connectors protected from standing water to extend service life. Typical installations include residential lawn systems, drip irrigation manifolds, and commercial landscapes.

• Direct burial-rated with UV-resistant outer jacket.
• Resists underground moisture and freezing temperatures.
• Not for hot-water or indoor mains wiring.
• Works with standard buried conduit runs and valve boxes.

How many valves and how far can this cable reach?

A 7-strand bundle lets you control up to six individual valves using the white conductor as the shared common, plus one conductor per valve. Each 18-gauge conductor can reliably transmit a 24 VAC signal up to about 800 feet to a valve solenoid, though actual distance depends on solenoid draw and controller output.

• Supports up to six valve solenoids plus a common return.
• 18-gauge conductors transmit 24 VAC up to ~800 feet (typical).
• For long runs check valve solenoid current to avoid voltage drop issues.
• Color-coded insulation simplifies zone mapping and maintenance.

Which brands and components is this compatible with?

This Orbit 7-conductor wire is compatible with major irrigation controllers and valves including Orbit, Hydro-Rain, Rain Bird, Hunter, and other common brands. The wiring standard—color-coded, 18-gauge conductors with a common return—matches industry norms so it integrates smoothly with existing systems.

• Works with Orbit, Hydro-Rain, and most major irrigation controllers and valves.
• Color coding reduces installation errors and speeds setup.
• Use standard waterproof connector kits at valve solenoids and splices.
• Fits valve boxes, manifolds, and conduit runs used in landscape irrigation.

Who this is for: Landscapers, irrigation technicians, and DIY homeowners who need a reliable, direct-burial control cable for multi-zone irrigation systems. Choose this Orbit 100 ft, 7-strand 18-gauge cable when you want clear conductor identification, weather-resistant protection for underground runs, and compatibility with common valves and controllers. For longer runs or higher-current solenoids, check gauge and distance requirements before specifying the cable.
