Abstract
A connector assembly for a plumbing appliance and for sealingly attaching an air admittance valve in a vent pipe. The connector assembly has an elastomeric sealing gasket with an interior threaded bore which is expanded by a rigid bottom portion of an air admittance valve. The bottom portion of the valve body has exterior threads and an expander portion which cooperates with the lower sealing ring of the sealing gasket to compress the elastomeric body of the sealing gasket against the interior of the vent pipe.
