Abstract: A seal assembly for accommodating misaligned conduits includes a first conduit, a second conduit, and a cup member. The first conduit has a first end and an opposed second end with a core. The core includes a spherical portion includes two separate seals axially spaced apart from one another relative to a longitudinal axis defined by the first conduit. An internal passage extends through the first conduit from the first end to the second end. The second conduit has opposed first and second ends. The first end of the second conduit defines a first socket portion and an internal passage extends through from the first end to the second end of the conduit. A cup member defines a second socket portion, which together with the first socket portion, defines a socket for sealably capturing the core spherical portion and accommodating axial misalignment of the first and second conduits.
