Abstract: A connector is described for connecting a pipe to a plate through an opening in the plate. The connector includes a resilient gasket sleeve with an internal bore wall that is slidably receivable over the pipe, and an external wall that is receivable through the plate opening. A rim and a retainer wall member are provided on opposite ends of the gasket sleeve, interconnected by a number of threaded fasteners. The entire unit can be inserted through the plate opening from the top side thereof so the gasket sleeve is received over the pipe and the rim abuts the top surface of the plate. The fasteners can then be tightened drawing cam surfaces on the rim and retainer together axially to deform the gasket sleeve. In doing so, the internal wall of the sleeve is expanded inwardly to securely seal and grip the pipe while the external wall is expanded outwardly to securely grip and seal against the plate.
