ABSTRACT:
A flexible joint for conduit includes inner and outer conduit members having telescoped end portions. The end portion on one member has a generally spherical surface portion facing toward the end portion of the other member and lying generally on the surface of a sphere having a sphere center intersecting the longitudinal axis of the one member. Sealing means extends from the other conduit member in sealing engagement with the spherical surface portion. Diagonally opposite pivot connections pivotally connect to the two members on a pivot axis which intersects the sphere center. The sealing means remains sealingly engaged with the spherical surface portion during limited pivotal movement of the two conduit members relative to one another about the pivot axis. The pivotal connections include selective adjustment means for moving the two conduit members relative to one another generally parallel to their longitudinal axes for varying the force with which the sealing means and spherical surface portion engage one another.
