Brand: K-Rain SKU: P15H
Product Overview
The K-Rain P15H is a male-threaded fixed half-circle spray nozzle for watering along straight boundaries, sidewalks, driveways, walls, and property edges. Its nominal 180-degree pattern fits compatible female-threaded spray risers, including K-Rain K-Spray bodies.
K-Rain’s performance data lists an approximate 13-foot radius and 1.20 GPM flow at 20 PSI. At 30 PSI, the published radius is approximately 16 feet with 1.80 GPM flow. At 40 PSI, the radius reaches approximately 17 feet with 2.20 GPM flow. The pressure-specific values should be used when sizing the zone and establishing head-to-head spacing.
The arc is fixed at half circle. A compatible radius-adjustment screw can reduce the throw, but it does not convert the nozzle to another arc. Actual coverage depends on pressure at the nozzle, wind, elevation, spacing, and landscape conditions.

Frequently Asked Questions
Can the arc be adjusted?
No. P15H is a fixed half-circle nozzle, although the radius may be reduced.
What is the published flow at 30 PSI?
Approximately 1.80 GPM with about a 16-foot radius.
Does it fit a K-Spray body?
Yes, when the body has the compatible female-threaded riser.
Why Buy This K-Rain P15H from Big Frog Supply?
Big Frog Supply lists the exact half-circle pattern and pressure-specific flow, helping customers distinguish it from the quarter- and full-circle models that look similar but place very different demand on the zone.
