摘要： A fire protection sprinkler with a push-in connection includes a sprinkler body having an input orifice for receiving fluid and an output orifice for outputting the fluid, the body having a push-in connection at the input end and a base portion. The push-in connection is adapted to be connected to a pipe fitting by insertion and has a plurality of recesses, a first recess having a first gasket, a second recess having a second gasket, and a third recess having a retaining clip. A frangible element is held in place by a set screw and a stopper. The frangible element is designed to fail at a predetermined temperature to release the stopper. A deflector is positioned on the base portion and configured to direct the output fluid toward the output end, upon activation of the sprinkler by failure of the frangible element at the predetermined temperature.
