Abstract
A method for using a pre-assembled coupling assembly, the method including providing a 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, a portion of the pipe fitting within the gasket positioned radially outward from a portion of the gasket; and assembling a housing around the gasket, the housing and the gasket forming a coupling, the coupling retained on the inner end of the pipe fitting when the coupling is in a relaxed position.
