Abstract
A fire suppression sprinkler adapted to receive arcuate surfaces of a grooved coupling is retainable to the coupling in a pre-assembled state. The coupling joins the sprinkler in facing axial end-to-end relation directly to grooved pipe. The sprinkler has a monolithic body which defines a bore having an inlet and an outlet. A groove, positioned between the inlet and the outlet extends around the body. A gap between the inlet and the grooved pipe to ensure the sprinkler and the pipe are joined by the coupling spaced apart in facing end-to-end relationship.
