Abstract
A pipe fitting configured for engagement with a coupling can include a first end, the pipe fitting defining a raised lip at the first end; and a second end disposed opposite from the first end, the pipe fitting defining a groove between the raised lip and the second end. A pre-assembled coupling assembly includes a coupling, the coupling defining a coupling bore extending through the coupling, the coupling including a gasket disposed within the coupling bore, the gasket being relaxed and uncompressed when the coupling is in a relaxed position; and a pipe fitting, the pipe fitting defining a first end and a second end, the first end inserted into the coupling bore, the coupling retained on the first end of the pipe fitting when the coupling is in the relaxed position.
