Abstract
The swivel joint comprises a housing holding a resilient annulus which in one embodiment sealingly engages an upper portion of a tubular head at the top of the dip tube, and an inward annular lip in the lower part of the housing swivelly supports the head from below. In another embodiment the resilient annulus in the housing serves to both seal and swivelly support the dip tube by its head.
