Brand: K-Rain SKU: 78003
Product Overview
The K-Rain 78003 is a 3-inch Pro-S professional pop-up spray body for residential and light-commercial turf and planting beds. Its male-threaded riser accepts compatible female-threaded fixed-arc, adjustable, or rotary nozzles, allowing the watering pattern to be selected independently from the body. A flush cap is installed for line flushing; the watering nozzle is sold separately.
The Pro-S design uses a rugged UV-resistant body and cap, co-molded wiper-seal cartridge, heavy-duty retraction spring, and ratcheting riser. These features support reliable pop-up, retraction, seal cleaning, and final pattern alignment. Current K-Rain specifications rate Pro-S bodies for 20 to 110 PSI with a 1/2-inch female NPT inlet. The 78003 provides approximately 2½ inches of riser travel and a retracted height of about 5 inches.
The standard 78003 does not include a check valve, pressure regulator, nozzle guard, or reclaimed-water marking. Those features are identified by model suffixes. K-Rain also states that the replaceable Pro-S riser assembly fits compatible Rain Bird 1800 Series spray cans, but confirm the exact body and its condition before reuse.

Compatibility and Installation Notes
Choose a compatible female-threaded nozzle and design for head-to-head spacing.

Add a suffix-specific model if pressure regulation, check-valve, guard, or reclaimed-water features are required.
