The RAIN BIRD X51000 is a spray head adapter designed for use with XBA-1800 series pop-up spray heads in residential and light commercial irrigation systems. This adapter provides a 10/32 threaded connection, allowing technicians and irrigation installers to attach nozzles or other compatible components to the spray head body. At 0.01 pounds, it is a lightweight fitting built for straightforward field installation. Licensed irrigation contractors and experienced DIYers alike rely on this type of adapter when servicing or retrofitting existing sprinkler zones.
This adapter is suited for in-ground irrigation applications where XBA-1800 series spray heads are already installed. It fits into standard spray head replacement and retrofit scenarios, making it a practical component to stock for routine service calls on residential lawns, garden beds, and small commercial turf areas. It is typically used when replacing worn nozzle seats or adapting a spray body for a specific nozzle thread pattern.
Designed for use with RAIN BIRD XBA-1800 series pop-up spray heads. Confirm thread pattern and spray body model before installation.
Installation is performed by irrigation technicians or qualified landscape professionals. Shut off the irrigation zone and relieve system pressure before removing or replacing any spray head components. Hand-tighten the adapter to the spray body to avoid cross-threading the 10/32 connection. Follow local plumbing and irrigation codes as applicable.
