A swivel for transmitting fluid between a male housing and female housing includes a bearing assembly and seal ring assembly. The seal ring assembly comprises a pair of seal rings each including a plastic ring having a generally U- shaped cross-sectional configuration defining a stop leg for static sealing engagement with a stop surface of one housing and an opposing dynamic leg. Each seal ring member also includes an elastomeric ring which is fitted within the cavity for urging the dynamic leg axial away from the stop leg, and for maintaining a static seal with a static sealing surface on the respective housing. The swivel of the present invention is particular well suited for use between a hose and a fill valve of a propane or LPG gas tank. The swivel of the present invention is able to withstand jarring and shock, and has surprisingly long life and low maintenance.
