Abstract
A multi-component flow passage assembly is disclosed which incorporates an improved sealing adaptor structure. The adaptor includes a generally-cylindrical adaptor body with a rim for seating on the periphery of a first flow passage section, e.g. a vacuum cleaner horn. The adaptor body is made to include a bead which is received within a lip on the horn. The rim includes a sealing ring section in the shape of an O-ring for sealingly engaging the perimeter of a second flow passage section, which is connected to e.g. a vacuum cleaner attachment. The present assembly provides a better seal and simplified construction over previous devices.
