Rain Bird a37461 6 Inch RD1800 Spray Head 45 Psi

Product Description

The RAIN BIRD a37461 is a 6-inch pop-up spray head from the RD1800 series, designed for residential and commercial irrigation systems. It features a built-in 45 PSI stainless steel pressure regulator that maintains consistent flow and protects downstream components from pressure spikes. The head incorporates Flow-Shield technology, which uses a black cap to help technicians quickly identify and troubleshoot flow-related issues in the field. Installation is handled by irrigation technicians and qualified landscaping professionals.

This spray head is suited for turf and landscape irrigation zones where pressure regulation at the head is required. The 6-inch pop-up height makes it appropriate for taller ground cover or turf applications where a standard 4-inch head would not achieve adequate coverage. The stainless steel regulator resists corrosion in both high-mineral and reclaimed water environments. The black Flow-Shield cap provides a visual indicator that distinguishes regulated heads from non-regulated heads within the same zone or system.

Key Features

• Built-in 45 PSI stainless steel pressure regulator maintains consistent operating pressure at the head
• 6-inch pop-up height suited for taller turf and dense ground cover applications
• Triple-Blade Wiper Seal resists debris intrusion and prevents stem from sticking in the raised position
• Flow-Shield technology uses black cap color-coding to aid in field identification and system diagnostics
• Stainless steel regulator construction offers corrosion resistance in reclaimed and high-mineral water applications

Compatibility

Designed as an OEM-style replacement for RD1800 series pop-up spray heads in residential and commercial irrigation systems requiring integrated pressure regulation.

Installation Notes

Installation should be performed by a licensed irrigation technician or qualified professional in accordance with local plumbing and irrigation codes. Shut off the irrigation system and depressurize the supply line before removing or installing any spray head. Ensure the threaded inlet connection is fully seated and sealed to prevent leaks at the fitting. Do not exceed the rated operating pressure for the zone to avoid damage to the regulator or adjacent components.
