K-Rain RPS50 4-Inch 1/2-Inch Gear-Drive Rotor
Brand: K-Rain | SKU: RPS50
Product Overview
The K-Rain RPS50 is a compact 4-inch gear-driven rotor for smaller lawn and landscape zones that need more reach than many conventional spray heads. Its 1/2-inch female NPT inlet can suit compatible mini-rotor and spray-body replacement projects when the piping, pressure, flow, and spacing support rotor operation.
The RPS50 provides adjustable part-circle or full-circle coverage and uses interchangeable nozzles to help match the zone’s hydraulic requirements. Before ordering, confirm the connection size, available dynamic pressure, total zone flow, required radius, and precipitation rate of the other heads operating on the same valve.

Compatibility & Installation Notes
Confirm that the zone can supply the required pressure and flow for every operating rotor. Use head-to-head spacing based on the chosen nozzle and actual site conditions. Install the body level with finished grade and flush the lateral line before inserting the nozzle. Avoid mixing it with unmatched sprays or rotors unless precipitation rates are intentionally coordinated.
Frequently Asked Questions
What radius can the RPS50 cover?
Its approximate radius is 18–33 feet, depending on the nozzle, pressure, and site conditions.
Can the RPS50 replace a standard spray body?
It may fit some 1/2-inch connections, but the zone must also provide suitable rotor pressure, flow, spacing, and matched precipitation.
Can it water a full circle?
Yes. Its arc adjusts from 40° through 360°.
Is a check valve included?
Do not assume one is included unless the selected model specifically states that configuration.
Why Buy the K-Rain RPS50 Rotor?
Big Frog Supply organizes the connection, radius, flow, arc, and installation details so homeowners, contractors, and maintenance teams can compare the RPS50 with spray heads and larger rotor SKUs before ordering.
