Brand: Hunter Industries SKU: PROS-04
Product Overview
The Hunter PROS-04 is a professional-grade 4-inch pop-up sprinkler body for residential and commercial spray-irrigation systems. It accepts compatible female-threaded spray nozzles and MP Rotator nozzles, allowing the installer to select the pattern, radius, and flow required for the landscape. This product is the sprinkler body only; a watering nozzle is sold separately.
The PROS-04 uses a pressure-activated, co-molded wiper seal to help limit flow-by and keep debris away from the riser. A heavy-duty spring supports reliable retraction after the zone shuts off, while the two-piece ratchet allows the riser position to be aligned after installation. The included directional flush plug helps keep debris out of the body during system flushing and installation.
