Abstract
A submersible large diameter pipe swivel is provided with seal means which is designed and adapted to allow small radial and axial relative movements (wobble) between the pipe and the swivel joint, while maintaining full integrity of the seal and which, being unaffected by such wobble, therefore offers minimum resistance to rotation.
