K-Rain 60003 RPS Select 4-Inch 3/4-Inch Rotor

K-Rain 60003 RPS Select 4-Inch 3/4-Inch Rotor

Brand: K-Rain    SKU: 60003

Product Overview

The K-Rain 60003 RPS Select is a 4-inch gear-driven rotor with four built-in selectable nozzles. Instead of removing and storing a separate nozzle tree, the installer turns the top selector with a flat-blade screwdriver or compatible adjustment key to choose nozzle 1, 2, 3, or 4. Matching the nozzle selection to the arc helps maintain more consistent precipitation across quarter-, half-, three-quarter-, and full-circle locations.

The rotor adjusts from 40° to 360° and is factory preset near 180° with the #2 nozzle selected. K-Rain’s guidance pairs nozzle #1 with arcs from about 40° to 135°, #2 with 136° to 225°, #3 with 226° to 315°, and #4 with 316° to 360°. Current specifications list an approximate 33- to 46-foot radius, 1.3- to 6.8-GPM flow range, 30- to 70-PSI pressure range, and a 3/4-inch female NPT inlet.

The universal riser assembly fits compatible Hunter PGP and PGP Ultra cans, making the RPS Select useful for certain retrofit applications. All primary adjustments are made from the top, including nozzle selection, arc, and radius. A check valve is not installed in the base 60003 unless the model number includes CV. K-Rain’s box-level check-valve statement should not be interpreted as multiple check valves included with one individual rotor.

Key Features

• Four built-in selectable nozzles
• No loose nozzle tree required for normal selection
• Matched precipitation when nozzle selection is paired with arc
• 40° to 360° adjustable arc
• Approximate 33- to 46-foot radius
• Approximate 1.3- to 6.8-GPM flow range
• 30- to 70-PSI operating range
• Universal riser fits compatible Hunter PGP and PGP Ultra cans

Common Uses

• Residential and light-commercial turf zones
• Installations where multiple arc settings share one zone
• Service fleets seeking fewer loose nozzle racks
• Retrofitting a compatible PGP-style rotor can

Technical Specifications

• Pop-up height: 4 inches
• Inlet: 3/4-inch female NPT
• Arc adjustment: 40°–360°
• Radius: Approximately 33–46 feet
• Flow range: Approximately 1.3–6.8 GPM
• Operating pressure: 30–70 PSI
• Nozzles: Four built-in selectable flow paths

Compatibility & Installation Notes

Confirm the available dynamic pressure and zone flow, then select the nozzle that matches the arc and hydraulic design. The built-in selector does not eliminate the need for head-to-head spacing and matched precipitation. When reusing an existing can, inspect the body, seal surfaces, and threads before installing the riser. Flush the lateral line and complete top adjustments according to current K-Rain instructions.

Frequently Asked Questions

Yes. The nozzle selector changes among four built-in flow paths without removing a conventional nozzle.

Which nozzle is used for a half-circle rotor?
K-Rain recommends nozzle #2 for arcs from approximately 136° to 225°.

Does 60003 include a check valve?
No. Select 60003-CV when a factory check-valve model is required.

Why Buy the K-Rain 60003 RPS Select 4-Inch 3/4-Inch Rotor?

Big Frog Supply organizes the selectable-nozzle ranges, arc, radius, flow, pressure, inlet, retrofit compatibility, and check-valve distinction so homeowners, contractors, and maintenance teams can compare the 60003 with conventional and factory check-valve rotor models before ordering.
