Brand: Hunter Industries SKU: PSU0417A
Product Overview
The Hunter PSU-04-17A is a 4-inch PS Ultra pop-up sprinkler supplied with a factory-installed gray 17A Pro Adjustable spray nozzle. The Big Frog Supply SKU is stored as PSU0417A. Unlike a body-only spray head, this assembly arrives with the watering nozzle installed and is designed to provide an adjustable pattern from shutoff through a full 360-degree arc with a nominal radius of approximately 17 feet at Hunter’s recommended 30 PSI nozzle pressure.
The compact PS Ultra body uses a male-threaded riser, two-piece ratchet, durable cap, and a large inlet filter screen. The 4-inch model provides double filtration through the nozzle screen and body filter to help reduce clogging. Its adjustable arc allows the installer to shape coverage around turf edges, planting beds, corners, and irregular landscape boundaries without changing the nozzle.
Hunter lists an operating pressure range of approximately 20 to 70 PSI for the PS Ultra assembly. Actual radius and flow vary with pressure, arc setting, wind, spacing, and field adjustment. The installed 17A nozzle has an approximately 28-degree trajectory. Where pressure is higher than the nozzle’s recommended operating point, system-level or body-level regulation may be needed to reduce misting and maintain the intended pattern.
