ABSTRACT:
A fluid swivel coupling is provided for interconnecting two fluid conduits so that they may swivel or rotate about their common axis. The coupling includes a swivel body connected to one fluid conduit and adapted to accept for rotational movement therein a spindle which is connected to a second fluid conduit and which is provided with an axial fluid bore which communicates between the two fluid conduits. The swivel coupling further includes a packing seal for preventing leakage between the swivel body and spindle. That part of the coupling moving with respect to the packing seal is formed of a very hard, wear resistant material in order to prevent leaking as a result of wear.
