Toro Precision O-15-HP 15' Pressure-Compensating Half-Circle Nozzle

The Toro Precision O-15-HP is a pressure‑compensating, half‑circle spray nozzle engineered to deliver uniform coverage with low precipitation rates for efficient landscape irrigation. It pairs Toro’s patented H2O chip technology with an optional factory pressure‑compensating disc (PCD) to reduce runoff and match soil infiltration rates across a 15-foot radius.

• Designed radius: 15 ft (4.6 m) half‑circle (180°) coverage.
• Thread type: Female-threaded connection for standard spray bodies and retrofit installations.
• Pressure compensation: Elastomeric PCD maintains consistent output at higher inlet pressures (factory PCD typically performs well near 40–50 psi).
• H2O chip technology: Produces uniform droplet size and clean edge definition for improved distribution and wind resistance.
• Low precipitation rate: Matched precipitation at approximately 1"/hour (25 mm/hr) to minimize runoff and improve watering efficiency.
• Compatibility: Works with common spray bodies and is available in multiple arcs and radii for mixed‑zone design.

Installation is straightforward: press the nozzle into the spray body and verify arc and radius at design pressure. Because the Precision family reduces flow compared with many conventional nozzles, it can lower overall system demands and allow more efficient valve and station sizing. Consult the Toro Precision Series performance data for detailed flow vs. pressure tables and arc performance when planning mixed‑radius zones.

Ideal for irrigation professionals and contractors who need reliable, water‑saving spray performance in turf and landscaped areas. Use factory performance tables to select matching nozzles for uniform precipitation across each zone and to confirm recommended operating pressures for PCD and non‑PCD models.
