Hunter Pro-Spray PRS pressure-regulated spray bodies

A pressure-regulated spray body holds the outlet at a fixed PSI — 30 PSI on the brown-cap PRS30, 40 PSI on the gray-cap PRS40 — regardless of what the supply line is doing. Pick PRS30 for traditional fixed-arc and Pro Adjustable nozzles; pick PRS40 for Hunter MP Rotator zones. Both come in 4", 6", and 12" risers, with or without check valves.
