Abstract
The present disclosure is directed to a sprinkler assembly that includes a sprinkler head and a fitting. The fitting has a recess in a distal end for receiving a pipe end. The fitting also has a sealing ring in the recess to provide a fluid-tight seal between the sprinkler head and the pipe end upon installation of the pipe. In one embodiment, the pipe is installed by pushing the pipe end into the fitting (i.e., pushing actuates the fitting). In another embodiment, the pipe is installed by inserting the pipe end into the fitting and using a tool to press-actuate the fitting. During installation, a sharp-edged grip-ring or grab-ring in the recess of the fitting, which in some embodiments has a plurality of teeth, engages the outer surface of the pipe end, holding the pipe securely in place.
