Abstract
An all metal ball and socket joint for connecting two misaligned conduits in fluid-tight communication utilizes a metal seal ring having a substantially conical bore which provides a relatively flush bore profile to fluid flowing through the seal ring. The cone angle of the conical bore is chosen in accordance with the maximum misalignment expected. The seal ring is attached to the nose of the ball member preferably by bolts. Seals are pressure energized by fluid flow. An annular o-ring groove and a pressure port can be provided to allow a back seal test to be carried out during installation.
