Orbit 54521 - 4 Professional Pop-Up Spray Head Sprinkler with Brass Quarter Pattern Nozzle

The Orbit's professional series spray head is the premium offering in their lineup, featuring a highly innovative pressure regulator that can be adjusted from the bottom or top of the can to 30 or 40 PSI. The 30 PSI setting is recommended for spray nozzles, while the 40 PSI setting is recommended for multi-stream rotator nozzles. This spray head is available in 2-, 3-, 4-, 6-, and 12-in. riser stem heights, making it ideal for a broad range of landscape types.

The spray head's durable metal cap protects it from power equipment damage, making it suitable for placement along sidewalks and driveways. The wiper seal features an over-molded structural support that ensures long-term, smooth retraction and prevents water from blowing by the riser stem. The corrosion-resistant stainless steel riser spring creates the pop-up action, ensuring years of reliable operation.

A ratchet mechanism in the riser stem allows you to adjust the direction of the spray after installation. The bottom of the can has an integral silt trap, while the spray body inlet has standard 1/2-in. female pipe threads (FPT) that connect to Blu-Lock and Riser-Flex fittings, as well as 1/2-in. Schedule 80 PVC and cut-off risers.

The adjustable pattern spray nozzle is engineered to deliver uniform droplet sizes across a 0-to-360-degree arc. It includes a filter and adjustment screw, allowing you to reduce the spray pattern down to 75 percent of its rated distance. Its low-angle trajectory helps improve efficiency by minimizing wind drift, making it suitable for outdoor irrigation use with cold water only and watering areas with up to 15 ft. of spacing between sprinkler heads.

The professional-grade pop-up spray body is available in 2- and 4-in. riser stem heights, featuring a corrosion-resistant stainless steel riser spring for years of reliable operation and a ratcheting riser stem that allows fine-tuning of the spray direction after installation. The precision-molded nozzle ensures consistent quality of the spray pattern, and the spray head is compatible with Orbit, Hydro-Rain, Rain Bird, Hunter, and other major brands.
