Breakdown

A cap for compatible 1800 series spray bodies
The Rain Bird 1800CAPS is a spray head cap for compatible Rain Bird 1800 series sprinkler bodies. It belongs in service work where an unused spray body needs to be closed as part of a planned irrigation change.
The part is small, so it should live in a labeled sprinkler bin with risers, nozzle screens, removed nozzles, and station tags.
Cap work still needs a live check
A capped head location should be checked while the zone is running. Watch the cap area, nearby soil, and surrounding heads so the service note reflects what happened under water pressure.
Write the station name, capped head location, cap part, and leak-check result before the area is covered or tools are put away.
Store it with the body family
Sprinkler caps can look similar in a small parts case. Keep this cap labeled for Rain Bird 1800 series spray bodies so it does not get mixed with hose caps, drip caps, or rotor parts.
If a removed internal assembly is being saved, bag it with the station name and date.
