ABSTRACT OF THE DISCLOSURE. A rotary joint for introducing or removing a heat exchanging medium, such as steam, from a rotary dryer drum characterized by its ability to accommodate significant axial expansion or contraction with respect to the axis of drum rotation. A rod supported housing includes an axially displaceable nipple having an end engaging an annular seal ring associated with a drum journal mounted wear plate. Axial movement between the wear plate and joint housing is accommodated by relative movement between the housing and nipple, and preferably, springs axially bias the nipple into engagement with a self-aligning seal ring to maintain a fluid tight connection under all thermal and pressure conditions.
