Overview

The Hunter PRS40 4-inch Pop-Up Sprinkler Body (PROS04PRS40) delivers precise, pressure-regulated irrigation for residential lawns, gardens, and light commercial landscapes. Factory-set to 40 psi, it is optimized for MP Rotator nozzles to promote even water distribution while helping reduce misting and runoff. The 4-inch pop-up height ensures uniform coverage even when turf is taller or denser. A rugged housing, stainless steel spring, and chlorine-resistant co-molded wiper seal are built to withstand debris, chemicals, and harsh weather. The gray cap aids quick field identification of the 40 psi model, and the standard 1/2 inch FNPT inlet supports quick, straightforward installs. Nozzle sold separately, and it fits all female-thread nozzles including Hunter MP Rotator.
