Weathermatic B12-Q Brass 5500 Spray Nozzle - 12 ft, 90°

The Weathermatic B12-Q is a B-Series (formerly 5500 series) brass quarter-circle spray nozzle engineered for consistent, matched precipitation in residential and commercial irrigation systems. Its milled brass construction delivers durability and highly uniform water distribution across arcs and angles.

• 12 ft spray radius at standard operating pressures, suitable for turf and shrub borders.
• 90° quarter-circle pattern designed for corners and edge runs where matched precipitation is required.
• Milled brass body and precision orifice for long life, corrosion resistance, and even precipitation.
• Compatible with 5500 series spray bodies and industry-standard fittings: fits LX/LXS heads, 72/73 shrub adapters, and standard male-thread risers; 1/2" female inlet connection.
• Recommended operating pressure 20–30 PSI (maximum 30 PSI); precipitation and performance measured to ASAE industry standards.
• Provides matched precipitation rates between arcs within the radius; typical full-circle precipitation around 1.2"/hr at 20 PSI (see catalog for complete tables).

Easy to install and service, the B12-Q is ideal for precise edge watering, corners, and irregular landscape layouts where reliable, uniform coverage is critical.
