Orbit underground sprinkler wire 5-strand 18‑gauge, 100 ft — color‑coded, UV‑resistant for irrigation control

Orbit 5-strand 18-gauge underground sprinkler wire delivers five insulated copper conductors in a UV-resistant jacket to reliably connect your controller to up to four valves plus a common return.

This 100-foot roll is built specifically for irrigation control wiring: each colored strand carries 24 VAC from the controller to valve solenoids while the white strand serves as the common (ground) return. The cable is designed for direct burial, resists moisture and freezing, and provides a tidy color-coded solution for new installs or repairs.

How does this wire simplify wiring multiple sprinkler zones?

The five-strand configuration groups four isolated valve leads plus a shared common conductor into one compact cable, cutting trenching and routing time. Color-coded insulation helps you match each valve to its station terminal quickly, reducing installation errors.

• Four colored conductors for individual valve runs
• White conductor used as the common/return
• Color coding minimizes miswiring during hookup
• Single bundle replaces multiple individual runs

Is this cable suitable for burial and outdoor conditions?

Yes—the jacket is a UV-resistant PVC designed for direct burial, so it stands up to sunlight exposure at the surface and to damp underground environments. The insulation protects the copper conductors from moisture and freezing conditions common in outdoor irrigation trenches.

• UV-resistant PVC outer jacket for surface exposure
• Moisture-resistant insulation for buried runs
• Rated for outdoor cold-water irrigation systems
• Use waterproof connectors at splices to reduce corrosion risk

What electrical performance and compatibility should I expect?

Each conductor is 18 AWG copper sized to carry 24 VAC signals from controllers to valves; under typical conditions a single conductor will reliably carry a solenoid connection up to the distances recommended by the manufacturer. The product is compatible with Orbit controllers and valves as well as most major irrigation brands that accept 18-gauge control wiring.

• 18-gauge copper conductors for standard 24 VAC solenoids
• Each conductor supports long runs per manufacturer's guidance
• Works with Orbit, Hydro-Rain and other common controllers/valves
• Recommended waterproof connectors at valve solenoids and splices

How do I handle splices, grounding and installation best practices?

Strip each insulated strand with wire cutters and use waterproof wire connectors at valve manifolds and any buried splices to prevent corrosion. Tie the white wire to the controller’s common (C) terminal and route each colored conductor to the corresponding zone or station terminal for straightforward troubleshooting.

• Strip each conductor carefully with wire cutters
• Attach colored wires to station terminals, white to common (C)
• Seal splices with waterproof connectors or gel-filled caps
• Avoid running parallel to high-voltage lines to reduce interference

Who this is for: Landscapers, irrigation installers, and DIY homeowners who need a compact, weather-resistant control cable to manage multiple sprinkler valves will find this Orbit 5-strand 18-gauge wire practical and reliable. It’s ideal for new lawn or garden systems, retrofit projects where fewer trenches are preferred, and maintenance work where durable, color-coded conductors streamline valve identification and repair.
