Brand: K-Rain SKU: PFSA
Product Overview
The K-Rain PFSA is a fixed shrub adapter with male nozzle threads for installing compatible female-threaded spray or rotary nozzles on a rigid 1/2-inch riser. It provides above-grade nozzle mounting for shrub beds, groundcover, planters, and other locations where a pop-up body is unnecessary or where the nozzle must remain elevated above vegetation.
The lower connection accepts a 1/2-inch male NPT riser, while the upper male thread accepts female-threaded K-Rain Pro-S-compatible nozzles, including approved fixed, adjustable, or rotary models. The adapter itself has no pop-up movement, pressure regulation, check valve, filter, or watering pattern. The nozzle and riser are purchased separately.
Fixed shrub risers remain exposed above grade and should be placed where they will not create a trip, mower, or impact hazard. Confirm local irrigation requirements, protect the installation from mechanical damage, and use pressure regulation appropriate for the selected nozzle.
