Orbit 5-Pack 54028 Plastic Pop-Up Flush Heads with Brass Half-Pattern Nozzle

Overview

The Orbit 5-Pack 54028 combines durable plastic pop-up flush heads with a brass half-pattern nozzle, designed to keep aging irrigation systems in service. The pop-up action adds a touch more spray height, making it easier to cover lawn areas while maintaining a low-profile profile for shrubs and flowerbeds. These heads suit older installations where a compact footprint matters, offering reliable performance without a complete system overhaul.

With compatibility in mind, the flush heads use a 1/2" female pipe thread and are typically mounted on a 1/2" male pipe thread riser or rigid PVC. This makes them a practical upgrade for existing lines from major brands, including Orbit and Champion. A handy flush head wrench is available as an accessory, simplifying removal and replacement in landscaped areas that require minimal digging.

How the Brass Nozzle Works

The brass nozzle includes an adjustment screw that lets you reduce the spray pattern to about 75% of its maximum radius, which is 15 feet. This capability helps tailor coverage to narrow sections or edging without sacrificing overall zone performance. The nozzle is designed to be easily replaceable with a brass flush head spray nozzle featuring male threads, supporting straightforward maintenance or upgrades.

Usage and Safety Notes

These heads are non-pressure regulating, so local codes may require different equipment or configurations. They are intended for outdoor irrigation using cold water and are recommended to operate around 30 PSI. If your project involves Californias or other areas with strict regulations, verify code requirements before installation.
