A sealed joint assembly for transmitting high temperature and high pressure fluid between adjoining ducts in, for example, an aircraft bleed air system, includes a gimbal ring and two annular clevises. Each clevis includes a pair of axially-extending lobes that each includes a bore hole extending therethrough. The bore holes of the clevis lobes may each align with a respective bore hole formed within the gimbal ring, through which a pin may be inserted to couple the clevises to the gimbal ring. The clevises and gimbal ring may be formed using additive manufacturing, and may be optimized to reduce the joint assembly's overall weight, while maintaining or improving its structural integrity. The gimbal ring may include a strut or truss network to enhance structural integrity, and may be comprised of an inner gimbal ring and an outer gimbal ring.
