ABSTRACT OF THE DISCLOSURE The invention pertains to a rotary joint wherein pres- sures imposed upon the joint by the pressurized medium therein are internally compensated. The joint is characterized by its ability to accomodate axial drum expansion, minimize rotative friction and the major joint components are self-aligning with respect to rotary motion. The basic components include a body member receiving an end of a nipple member, one of the members being fixed against axial displacement. A single annular nip- ple seal mounted upon the nipple member within the body member chamber engaging a seal ring constitutes the sole mechanical connection between the body and nipple members, and the fact that the nipple seal is axially displaceable upon the nipple member permits an internal compensation of axial forces pro- duced within the joint, permits accomodation of axial thermal expansion of the joint components, and the spherical configur- ation of the nipple seal provides self alignment between the body and nipple members.
