Orbit 5-Strand Underground Sprinkler Wire, 50 ft 18-Gauge — UV-Resistant Direct-Burial, Color-Coded

This Orbit irrigation control cable is built for outdoor, direct-burial use and made to resist moisture, freezing and sunlight exposure. Each of the five insulated strands contains an 18-gauge copper conductor and is sheathed in a UV-resistant PVC jacket, so you can run zone wiring from a controller to individual valves or a valve manifold. The multi-colored conductors simplify identification during installation and the white conductor serves as the common return to the controller’s “C” terminal.

How does this wire simplify wiring multiple irrigation valves?

The 5-strand configuration provides four individually colored conductors for separate zones and a dedicated white common conductor that ties all valve solenoids back to the controller. Using a single bundled cable reduces trenching and keeps runs neat at the valve manifold.

• Four color-coded conductors for individual zone connections.
• One white common conductor to connect all solenoids to the controller C terminal.
• Single bundled run replaces multiple separate cables for cleaner trenches.
• 50-foot length ideal for short- to mid-range installations, available in longer lengths elsewhere.

Is this cable durable enough for direct burial and outdoor conditions?

Yes — the jacket is formulated from UV-resistant PVC and the construction is rated for direct burial, resisting moisture and freeze-thaw cycles common in outdoor irrigation systems. Still, use waterproof connectors where splices occur to prevent corrosion and ensure long-term reliability.

• UV-resistant PVC jacket shields conductors from sunlight and surface exposure.
• Rated for underground burial and outdoor moisture exposure.
• Designed to tolerate freezing conditions without cracking.
• Recommendation: use waterproof connectors at valve solenoids and splice points.

What electrical range and compatibility can I expect from an 18-gauge conductor?

Each 18-gauge conductor in this Orbit cable is appropriate for carrying the standard 24 VAC control signal used by most irrigation controllers and valves. According to manufacturer guidance, a single 18-gauge run will reliably carry the control signal to a solenoid at distances up to about 800 feet, depending on load and system configuration.

• 18-gauge copper conductors suitable for 24 VAC sprinkler control signals.
• Manufacturer notes reliable performance to approximately 800 feet under typical conditions.
• Works with Orbit and major irrigation brands including Hydro-Rain.
• Wire cutters/strippers recommended for clean conductor preparation.

What installation tips ensure a trouble-free irrigation connection?

Plan routes to minimize splices and keep cable slack for future valve access. Strip each colored strand carefully, identify the white common, and secure waterproof connectors at every solenoid and splice to avoid corrosion and intermittent faults.

• Label colored conductors at both ends before burying for easy troubleshooting.
• Leave service loops at the valve manifold for future repairs or expansions.
• Use waterproof wire connectors and heat shrink for exposed joins.
• Test continuity and controller outputs before final backfill.

Who is this for: Landscapers, irrigation contractors, and DIY homeowners who need a compact, color-coded cable for running up to four irrigation zones plus a common return in short to medium-length installations will find this Orbit 5-strand, 18-gauge, 50-foot cable practical and dependable. It’s especially useful when direct-burial runs and tidy valve manifolds are priorities, and when compatibility with common 24 VAC controllers and valve brands matters.
