Abstract
An expansion joint includes a pair of tubular fittings joined together by a bellows for accommodating differential movement therebetween. The fittings include balls at respective distal ends thereof which engage complementary sockets fixedly joined to opposite ends of the bellows. The respective ball and sockets additionally accommodate pivotal and rotary movement. The bellows allows pressure and spring forces to engage the sockets against their respective balls for continuously seating the balls in the sockets during operation and maintaining effective seals against leakage.
