K-RAIN PRO-S SPRAY 4 INCH

A compact 4-inch pop-up spray sprinkler body designed for K-Rain nozzles, built for residential irrigation zones requiring low-profile installation and reliable spray performance.

The K-Rain Pro-S 4 inch Spray is a professional-grade pop-up sprinkler body used in residential and light commercial irrigation systems. It provides a 4-inch (≈10 cm) pop-up height, making it suitable for turf areas, lawns, and low vegetation zones where minimal obstruction is expected.

This spray body is designed to accept all standard female-thread spray nozzles, including fixed-pattern, adjustable, and rotary nozzle types. It features a rugged housing, a heavy-duty retraction spring, and a co-molded wiper seal to ensure reliable sealing and consistent pop-up operation even in dirty or low-pressure conditions.

Some versions include optional upgrades such as a pressure regulator (typically 30 or 40 PSI), check valve to prevent low-head drainage, and nozzle guard protection. The 4-inch model is one of the most widely used spray body sizes due to its versatility and simple installation depth.

K-Rain Pro-S sprays are engineered for durability and compatibility with standard irrigation fittings and are often used interchangeably with other major brand spray bodies.
