1. A method for using a pre-assembled coupling assembly, the method comprising:
providing a pipe fitting comprising a raised lip, a sealing surface, and a groove, the pipe fitting defining an inner end and an outer end, the pipe fitting defining an axis;
axially inserting the inner end of the pipe fitting into a gasket comprising a center ridge, wherein:
the sealing surface of the pipe fitting is within the gasket and is positioned radially outward from the groove of the pipe fitting;
the raised lip of the pipe fitting extends radially outward from the sealing surface and into the center ridge of the gasket; and
the sealing surface of the pipe fitting is defined between the groove and the raised lip of the pipe fitting; and
assembling a housing around the gasket, the housing defining a gasket groove to receive the gasket, and the raised lip of the pipe fitting compressing the center ridge of the gasket within the gasket groove of the housing, the housing and the gasket being retained on the inner end of the pipe fitting when the coupling is in a relaxed position.
