Abstract
A fluid swivel coupling device for rotatably interconnecting a pair of fluid conduits. The coupling device includes a plastic swivel housing forming an internal cavity and a fluidly connected first port. The internal cavity includes a cylindrical inner surface having an annular housing retention groove and a spaced apart annular seal groove. A plastic tubular second swivel body portion extends between an internal end and a second port. The internal end is rotatably seated within the internal cavity and includes an annular retention groove opposing the housing retention groove and an annular seal groove opposing the seal groove within the housing. The second swivel body portion is fluidly connected with the first port to define an all plastic fluid passageway between the first and second ports. An annular seal is seated within the internal cavity between the opposing seal grooves for preventing fluid from leaking out of the cavity. A retention bearing is seated within the internal cavity between the opposing retention grooves and adapted to allow rotation of the second body portion while securing the second body portion within the cavity.
