Brand: Irritrol SKU: 533
Product Overview
The Irritrol 533 is a hand-adjustable flood bubbler for localized watering around shrubs, roses, flower beds, groundcovers, and individual plants. Its twist-top design lets the user adjust the water output by hand without a tool, including a true zero-flow shutoff for temporary maintenance or seasonal changes.
The bubbler uses a 1/2-inch female NPT connection and is designed for approximately 1.36 to 5.90 GPM. Irritrol recommends an operating range of 20 to 40 PSI and lists a maximum operating pressure of 75 PSI. The adjustable flood pattern is intended to apply water close to the plant rather than project a long spray radius. Heavy-duty ABS construction supports outdoor irrigation use, and a lavender version may be available for reclaimed-water identification.
