• Pressure regulator factory-set to 30 PSI, adjustable to 40 PSI (70 PSI max operating pressure)
• Corrosion-resistant stainless steel riser spring
• Ratcheting riser stem allows fine-tuning of spray direction after installation
• Dual radial and face seals on cap plus over-molded wiper seal for reliable retraction
• Gravity-activated silt trap in the bottom of the body helps prevent nozzle clogging

Tip: Match nozzle patterns within a single irrigation zone so all heads deliver a similar precipitation rate per square foot. Mixing Full, Half, Quarter, and Center Strip patterns on the same zone causes uneven coverage and over-watering in the shorter-arc segments.
