Weathermatic B18-H Brass Spray Nozzle, 18 ft Radius, 180°

2017-08-21T10:31:53-07:00

The Weathermatic B18-H is a precision milled-brass spray nozzle (originally part of the 5500 series) engineered for consistent, matched precipitation across an 18 ft radius and a half-circle 180° arc. Its mill-cut design produces fine, uniform droplets that fall closer to the head for improved coverage and water efficiency.

Model: B18-H (B-Series, formerly 5500).

Material: Milled brass construction for durability and long service life.

Radius & Arc: 18 ft radius; 180° (half-circle) spray pattern.

Performance: Designed for low-pressure, efficient operation—optimal performance around 20 psi; operating range typically 20–30 psi; max 30 psi.

Connection & Compatibility: Industry-standard female threads; fits Weathermatic LX sprayheads, LXS, 72/73 shrub adapters and most standard spray head risers.

Water Management: Matched precipitation rates between arcs for uniform coverage and simplified head-to-head spacing.

Maintenance: Single-port brass design resists clogging; can be cleaned in place without risk of damage.

Use the B18-H to upgrade existing spray heads or to specify reliable, long-lasting coverage in new installations. For design reference and nozzle charts, consult the manufacturer’s Brass Nozzles catalog sheet and B-Series technical documentation. The B-Series is identical to the former 5500 line and is widely used where uniform precipitation and durability are required.
