摘要 A misalignment ball joint fitting includes first and second body portion coupled together and having spherical inner surfaces. A ball secured inside the body portions has a passage therein. The passage has a funnel shaped portion in a first end portion of the ball. The ball is allowed to at least partially rotate when secured inside the first and second body portions. A guide sleeve is coupled to the first body portion. The guide sleeve is coaxial with the ball passage. A recess is in an inner surface of the ball near a center of the ball. An end of the guide sleeve extends into at least a portion of the recess when the ball is in a neutral position with walls of the passage in the ball parallel to walls of the guide sleeve.
