Brand: K-Rain SKU: P15F
Product Overview
The K-Rain P15F is a male-threaded fixed full-circle spray nozzle for interior lawn and planting areas that require a nominal 360-degree pattern. It fits compatible female-threaded spray risers, including K-Rain K-Spray bodies.
K-Rain’s performance data lists an approximate 13-foot radius and 2.40 GPM flow at 20 PSI. At 30 PSI, the listed radius is approximately 16 feet with 3.60 GPM flow. At 40 PSI, the published radius reaches approximately 17 feet with 4.40 GPM flow. These values are model-specific and should be used when calculating total zone demand and head spacing.
The arc is fixed at full circle. A compatible radius-adjustment screw can reduce throw, but it does not change the 360-degree pattern. Actual coverage varies with pressure at the nozzle, elevation, wind, spacing, and system hydraulics.

Frequently Asked Questions
Can P15F be adjusted to half circle?
No. It is a fixed full-circle nozzle. Only the radius may be reduced on a compatible installation.
What is the published flow at 30 PSI?
Approximately 3.60 GPM with a radius of about 16 feet.
Does it fit Pro-S?
Pro-S uses a male-threaded riser for female-threaded nozzles. P15F is male threaded and requires a female-threaded riser such as K-Spray.
Why Buy This K-Rain P15F from Big Frog Supply?
Big Frog Supply lists the exact thread direction, fixed arc, and pressure-based radius and flow so customers can calculate the zone correctly instead of assuming every 15-foot nozzle has the same water demand.
